(BDI) to prepare a Wastewater and Stormwater Facilities Plan (Plan) meeting the requirements of Chapter 62-503 for the State Revolving Fund (SRF) Loan Program. This Plan has been prepared to provide the necessary information required by the Florida Department of Environmental Protection (FDEP) in support of the SRF loan. The plan addresses ten individual projects previously identified by the City. Three projects are located at the wastewater treatment plant and are intended to provided redundancy, increased reliability, and better usability of reuse water. One project involves upgrades to an aging over capacity portion of the sanitary sewer collection system. Six projects involve improvement to the stormwater system to provide better treatment, reliability and conveyance capacity. Existing Conditions The City is located in northeast Brevard County along the east coast of Florida. The City encompasses an area of approximately 1.9 square miles with approximately 93% of the available land within the City already developed. The wastewater service area includes the entire incorporated limits of the City. The wastewater system consists of gravity collection, pumping (lift) stations, force mains, and a wastewater treatment facility with a permitted average daily flow (ADF) capacity of 1.8 million gallons per day (MGD). The original wastewater treatment facility was constructed in the late 1960’s. The WWTF was upgraded and expanded to the current 1.8 MGD in 1995. The 1995 improvements upgraded the facility to a 5-stage nutrient removal process that allowed the City to discharge effluent to both the public access reuse water distribution system and the Banana River. Additional facility improvements were made in 2005 to make more reuse water available and to switch disinfection to sodium hypochlorite. The City’s stormwater service area also includes the entire incorporated limits of the City. During the late 1950’s and through the 1960’s, the City and the Florida Department of Transportation (FDOT) constructed stormwater drainage systems that conveyed stormwater runoff from State Road A1A to the Banana River Lagoon. Outfall culverts are located at the following locations: Holman Road, Center Street, International Drive, and Central Boulevard. Additional stormwater outfalls are located at the Canaveral Drainage Canal, and the City’s Wastewater Treatment Facility. The stormwater system has historically demonstrated it has the capacity to prevent significant flooding. However, it was constructed prior to the implementation of water quality rules, and water quality treatment facilities are limited. City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 1-1 February 2013 1 INTRODUCTION 1.1 Background The City of Cape Canaveral (City) is located in northeast Brevard County along the east coast of Florida. The location of Cape Canaveral is shown on Figure 1-1. The City encompasses an area of approximately 1.9 square miles with approximately 93% of the available land within the City already developed. The wastewater service area includes the entire incorporated limits of the City. The wastewater service area for Cape Canaveral is shown on Figure 1-2. The wastewater system consists of gravity collection, pumping (lift) stations, force mains, and a wastewater treatment facility with a permitted average daily flow (ADF) capacity of 1.8 million gallons per day (MGD). The original wastewater treatment facility was constructed in the late 1960’s. The location of the Cape Canaveral Wastewater Treatment Facility is shown on Figure 1-3. The system is operated as a cascading lift station system, that is, the wastewater flows by gravity to a pumping station where it is pumped (lifted) into another gravity collection system until it reaches the treatment facility. The WWTF was upgraded and expanded to 1.8 MGD in 1995. This expansion effort upgraded the WWTF to a 5-stage nutrient removal process that allowed the City to discharge effluent to both the public access reuse water distribution system and the Banana River (Condition Assessment for the Cape Canaveral Wastewater Treatment Facility, June 2006, Brown and Caldwell). In 2005, additional upgrades were made including the construction of additional reuse water pumps, a cover on the reject storage tank to allow this tank to serve as reuse water storage, piping and automatic valving to allow the equalization tank to serve as reject effluent storage, and a sodium hypochlorite storage and feed system to allow the City to discontinue the use of gaseous chlorine. Dechlorinated effluent not used for reuse is discharged to the Banana River. Effluent water is transferred from the wet well to two reuse ground storage tanks by effluent transfer pumps. A 1.0 million gallon (MG) and a 1.4 MG ground storage tank store treated effluent or substandard effluent. The reuse water distribution system includes effluent transfer and reuse distribution pumps and distribution system piping (Capacity Analysis Report, Tetra Tech). The City’s stormwater service area also includes the entire incorporated limits of the City as shown on Figure 1-4. During the late 1950’s and through the 1960’s, the City of Cape Canaveral and the Florida Department of Transportation (FDOT) constructed stormwater drainage systems that conveyed stormwater runoff from State Road A1A to the Banana River Lagoon. Outfall culverts are located at the following locations: Holman Road, Center Street, International Drive, and Central Boulevard. Additional stormwater outfalls are located at the Canaveral Drainage Canal, and the City’s Wastewater Treatment Facility.

In the 1980’s, new projects that were constructed by the City included additional stormwater criteria approved by the SJRWMD. During the 1990’s the City underwent increased development and many areas that experienced growth tied into the City’s existing stormwater outfalls. Fortunately, the City’s existing drainage outfall system has the capacity to minimize flooding within the City. However, the pollutants that exist within the stormwater runoff have been discharged directly into the Banana River Lagoon (City of Cape Canaveral Stormwater Master Plan, Stottler Stagg & Associates). In 1987, Congress passed a series of amendments to the Clean Water Act. One of the provisions contained in the Act included the establishment of the National Storm Water Program and the reclassification of certain nonpoint sources of pollution as point sources subject to regulation under the Environmental Protection Agency (EPA) National Pollutant Discharge Elimination System Program (NPDES). By the year 2000, the Florida Department of Environmental Protection (FDEP) obtained state financing to assume control of the program. Today, the changing regulatory environment and increasingly stringent regulations governing the discharge of stormwater runoff into the Banana River Lagoon necessitate decreasing the pollutant and nutrient loading present in stormwater runoff into this protected water body. The City has identified six (6) projects in its Capital Improvement Plan shown on Figure 1-5 that would satisfy this condition and increase the water quality of future stormwater discharge in order to comply with regulatory criteria.

(BDI) to prepare a Wastewater and Stormwater Facilities Plan meeting the requirements of Chapter 62-503 for the State Revolving Fund Loan Program. This plan provides recommended improvements to the City’s existing facilities and additional facilities and improvements to meet the City’s future needs. The purpose of this report is to describe the City’s existing wastewater and reuse system and stormwater system then recommend specific improvements. In order to add redundancy and to improve aging equipment for the City’s wastewater and reuse system, improvements to the Oxidation Ditch and replacement of the belt filter press are needed. Sanitary sewer line rehabilitation is needed along Holman Road. Additional reuse storage capacity is needed to reduce treated effluent discharge to the Banana River. Stormwater improvements are needed including construction of a ditch culvert, construction of stormwater improvement along a new streetscape corridor, drainage pipe replacement, ditch dredging, and construction of a regional stormwater system at a city park. 1.3 Demographics Cape Canaveral is an urban community with a population of 9,912 per the 2010 Census. The median age is just over 51 years of age. The per capita income is reported as $32,440 versus a Florida/U.S. average of $26,551/$27,334. The nearest metropolitan area is Melbourne. Of the developed land within the existing corporate limits, 54.4% is Residential, 23.4% Commercial and 9.5% Industrial according the City’s Future Land Use map. It is anticipated that the City corporate boundaries will not significantly change in the future. 1.4 Document Contents This report is intended to provide the necessary information for the planning documentation required for the SRF loan program.

Rainfall for the area can be characterized by data available from the NOAA 085612 gauging station located at Melbourne International Airport. The 30-year average rainfall was 52.0, inches with the highest monthly rainfall, 7.7 inches, occurring in August and the lowest monthly rainfall, 2.1 inches, occurring in April (NOWData NOAA Online Weather Data web site). 2.2 Topography, Hydrology and Hydrogeology Cape Canaveral is primarily located within the Eastern Valley and Atlantic Coastal Ridge physiographic areas with little local relief and dune like ridges and swales parallel to the Atlantic Ocean. Elevations range from 0 feet NAVD 88 to 13 feet NAVD 88 within the City limits. For example, the City’s wastewater treatment facility has an elevation of 0 feet along the west property line and 13 feet NAVD 88 in the vicinity of Ocean Park Lane in the northeast corner of the City. According to the Soil Survey of Brevard County, Florida, prepared by the United States Department of Agriculture – Soil Conservation Service, the soils in the area are of the Canaveral soil series which are moderately well drained soils composed of sand mixed with shell fragments up to 80 inches in depth. The lower portion of the south end of Cape Canaveral is located within the Atlantic Coastal Ridge physiographic area which consists of sand ridges and swales and the remaining portion is located within the Eastern Valley physiographic province which includes lowlands with scattered marsh and wetland areas. The Cape Canaveral area is mainly comprised of soils of the Canaveral-Palm Beach-Welaka association with nearly level and gently sloping, moderately well drained to excessively drained soils of the Canaveral and Palm Beach soil series. This soil association is “made up of nearly level and gently sloping ridges interspersed with narrow wet sloughs that generally parallel the ridges” (Soil Survey of Brevard County, Florida). Soil borings performed by Ardaman & Associates, Inc. in 2010 at Manatee Sanctuary Park north and adjacent to the City’s wastewater treatment facility, showed that the ground water table is within 12 inches of the ground surface for 1 to 4 months and recedes to a depth of 36 inches and more for the remaining months of the year. City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 2-2 February 2013 The geologic formations in the Cape Canaveral area consist of fine to medium sand, coquina, and sandy marl with approximate thickness of 0 to 110 feet. The underlying Upper Miocene deposits are composed of gray to greenish-gray sandy shell marl, green clay, fine sand, and silty shell with approximate thickness of 20 to 90 feet. The next underlying formation is the Hawthorn Formation which includes light green to greenish-gray sandy marl, streaks of greenish clay, phosphatic radiolarian clay, black and brown phosphorite, thin beds of phosphatic sandy limestone. The soils within these stratigraphic units are of low permeability and generally serve as a confining unit for the Floridan Aquifer. The geologic formations underlying the Hawthorn Formation are the Ocala Group consisting of the Crystal River Formation approximately 0 to 100 feet in thickness, the Williston Formation approximately 10 to 50 feet in thickness, and the Inglis Formation approximately 70 feet or more in thickness. Generally, these formations consist of white coarse limestone containing coquina to fossiliferous fragments as depth from land surface increases. Beneath the Ocala Group lies the Avon Park Formation generally described as dense chalky limestone. The Floridian Aquifer is the major water producing aquifer for Brevard County and lies within these formations (Water Resources of Brevard County, Florida, Report of Investigations No. 28). According to the U.S. Geological Survey Water Resources of Brevard County, Florida Investigations No. 28, the Atlantic Coastal Ridge forms the thickest part of the surficial (non- artesian) aquifer. The surficial aquifer thins eastward and westward from the crest of the Atlantic Coastal Ridge. Sandy ridges that form a substantial portion of the barrier islands are sources of surficial water for local residents and commercial establishments. In Brevard County, the water table of the surficial aquifer ranges in depth from 0 to 22 feet below land surface but occurs generally at depths of less than 10 feet. The top of the Floridian Aquifer is approximately 75 feet below sea level in the northwestern part of Brevard County and more than 300 feet below sea level in the southeastern part (Soil Survey of Brevard County Florida). 2.3 Plant and Animal Communities A list of endangered, threatened, and other species of concern that may be found within Cape Canaveral as defined by the US Fish and Wildlife Service (USFWS) is provided in Table 2-1. The status for plants and animal communities listed can be identified as: • Endangered = E • Threatened = T • Candidate = C • Threatened (FFWCC) = ST City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 2-3 February 2013 Table 2-1 State and Federal Threatened, Endangered, and Candidate Species Status Common Name Scientific Name (State) (Federal) Birds: Audubon’s Crested Caracara Polyborus plancus audubonii T T Everglade Snail Kite Rostrhamus sociabilis plumbeus E E Florida Scrub-Jay Aphelocoma coerulescens T T Wood Stork Mycteria americana E E Mammals: Southeastern Beach Mouse Peromyscus polionotus niveiventris T T West Indian (Florida) Manatee Trichechus manatus E E Reptiles: Atlantic Salt Marsh Snake Nerodia clarkii taeniata T T Eastern Indigo Snake Drymarchon corais couperi T T Gopher Tortoise Gopherus polyphemus ST C Green Sea Turtle Chelonia mydas E E Hawksbill Sea Turtle Eretmochelys imbricata E E Leatherback Sea Turtle Dermochelys coriacea E E Plants: Carter’s Warea Warea carteri E E 2.4 Wetlands and Floodplain The City of Cape Canaveral contains few wetland bodies identified by the National Wetlands Inventory (NWI) as shown on Figure 2-1. NWI wetlands are grouped into five major categories: Estuarine, Lacustrine, Marine, Palustrine, and Riverine. The wetlands in the vicinity of Cape Canaveral are Palustrine, which are non-flowing wetlands that are small in size (less than 20 acres), shallow in depth, and contain vegetation including emergent plants within shallow ponds, marshes, swamps, and sloughs.

The proposed work for the collection and transmission system (including lift stations) will be completed within state and county maintained road right-of-ways and already developed land. Improvements for the wastewater treatment system will be conducted on existing sites already developed without wetlands present. As shown in Figure 2-2, Cape Canaveral is located primarily within Zone X on the flood maps and outside the 500-year flood plain. Other portions are within Zone AE along the Atlantic Ocean shoreline and the Banana River shoreline. Zone AE represents areas that are subject to inundation by 100-year flooding for which base flood elevations (BFE) have been determined. A small area within Zone AO exists along the east side of the city adjacent to the Atlantic Ocean. Zone AO is an area inundated by 100-year flooding (flood depths from 1 to 3 feet) for which average depths have been determined. The existing wastewater treatment facility site (WWTF) site is located within Zone X according to the FEMA Flood Insurance Rate Map (Panel 12009C0313 E – April 1989). 2.5 Archeological and Historical Sites There are no known historical sites for the planning area based on the Historic American Buildings Survey (HABS) and Historic American Engineering Record (HAER) collections from the National Park Service (NPS). The Director of the Division of Historical Resources is also the State of Florida’s State Historic Preservation Officer (SHPO) serving as liaison with the NPS. The location of structures identified by the Office of Cultural and Historical Programs (OCHP) within the Florida Department of State is shown on Figure 2-3. Based on the data available from OCHP, five (5) structures were identified as historical or archaeological sites within the existing Cape Canaveral City limits. Table 2-2 provides a listing of structures identified from the OCHP within the Cape Canaveral City limits. The elements of this project will have no impact on the archaeological and historical sites identified by the State. An inquiry was made to the Florida Department of State’s Division of Historical Resources to determine the existence of cultural resources within the planning area. The Florida Master Site File produced by the Division of Historical Resources lists nine (9) archeological sites within the planning area. These sites are shown on Figure 2-4. Table 2-3 provides a listing of the archeological sites within the existing Cape Canaveral City limits.

The population for the City has increased from 8,829 in 2000 to 9,912 in 2010. This population increase of 1,083 over this 11 year period results in a 12 percent increase or 1.1 percent average annual growth rate. Throughout these years, the City has seen five years with declining population (2006-2010) with 2010 having the greatest decline in population of 169 people. The largest increase was from 2004 to 2005 with a 6.7 percent increase in population.

The largest percentage of land is dedicated to residential land uses (54.4%). There are three (3) land use categories for residential lands: R-1 Low Density Residential (6.6%), R-2 Medium Density Residential (23.0%), and R-3 High Density Residential (24.7%). Commercial lands account for 29.8% with land use categories for C-1 Commercial (23.4%) and C-2 Commercial/Manufacturing (6.4%). %. Commercial development exists primarily along the City’s main corridor, State Road A1A. Commercial development contains retail businesses, offices, restaurants, convenience stores, automobile service stations and repair facilities. The remaining land use categories include industrial lands (9.5%) that are clustered along the City’s northern border, conservation lands (3.1%) along the northwest edge of the City, and public/recreation lands (3.2%) scattered throughout the City.

Within the City, most of the residential land use falls into two categories: R- 3, Duplex/Multi-Family/Townhouse Apartments (24.7%) with a maximum of fifteen (15) units per acre, and R-2, Medium Density Residential and Townhouse Apartments (23.0%), both with a maximum of fifteen (15) units per acre. The remaining residential land use category is R-1, Low Density Residential (6.6%) with a maximum density of 5.808 lots per acre. The Commercial land use categories C-1 and C-2, Commercial, have zoning regulations that impose a variety of requirements, depending upon type of use with land use percentages of 23.4% and 6.4%, respectively. The land use category, M-1, Light Industrial (9.5%) requires a maximum of 4.356 lots per acre. The land use category PUB, Public and Recreation Facilities land use category includes parks and playgrounds. Conservation lands (CON, Conservation) include private or public lands that are conservation easements, wetlands, or water bodies. 2.7.2 Population and Flows Population projections were obtained from the Capacity Analysis Report (CAR) for the Cape Canaveral Water Reclamation Facility submitted to the City by Tetra Tech in 2011. Population projections in the CAR were obtained from earlier reports by Brevard County and Miller Legg. Historical population data from 2001 through 2009 was obtained from the U.S. Census Bureau. The projected population for 2010, 11,137, was obtained from previous reports by Brevard County and Miller Legg. The U.S. Census Bureau actual population for 2010 is 9,912. The difference between the values for the 2010 population is 1,225 or 12 percent. The higher population estimate, 11,137 was used as a basis for the population estimate for the years 2011 through 2020. The population projections from 2011 to 2020 presented in the CAR are therefore conservative as are the estimates for population determined in this report for 2021 through 2028. Average flows per capita were calculated in the CAR using FDEP Monthly Operating Reports whereby Annual Average Daily Flow (AADF) values were calculated for each year of the study period from 2001 through 2010. An average flow per capita value of 103 gallons per day (GPD) was calculated from the AADF values for the years 2001 through 2010.The projected AADF was calculated by multiplying the projected population values by 103 GPD, the average flow per capita. The maximum three (3) month AADF was calculated by multiplying the AADF by 1.2, the average value calculated for the ratio of the average maximum three month AADF to the AADF for the each of the years 2001 through 2010 as shown in Table 2-6. Table 2-7 shows the Historical Average Flow per Capita and with population, AADF and maximum three month AADF values projected to 2028. This table extends projections for the aforementioned values to 2028 using methodologies presented in the CAR. Population, AADF, and maximum three (3) month AADF values for 2006 through 2020 were excerpted from the CAR. The years 2006 through 2010 include population data derived from statistics and estimates and average flow data obtained from FDEP monthly Operating Reports. Population estimates from 2021 through 2028 were derived by utilizing the rate of growth in population given for the years 2019 and 2020 in the CAR. This rate of growth was applied consecutively to each year in order to obtain an estimate of the City’s population in 2028. The City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 2-14 February 2013 AADF values for the years 2021 through 2028 were calculated by multiplying the population by 103 GPD, the average flow per capita. The maximum three (3) month values for the same time period were calculated by multiplying the AADF by 1.2, the average value calculated for the ratio of the average maximum three month AADF to the AADF for each year as shown in Table 2-6. Table 2-6 Three Month Average Daily Flows (2001-2011) Year Max 3 Month AADF (MGD) Month of Maximum Flow Annual Average Daily Flow (AADF) (MGD) Maximum Three Month AADF: AADF Ratio 2001 1.10 November 0.83 1.3 2002 1.20 August 0.97 1.2 2003 0.95 January 0.89 1.1 2004 1.06 September 0.91 1.2 2005 1.32 October 1.06 1.2 2006 1.09 March 1.05 1.0 2007 1.27 October 1.06 1.2 2008 1.61 September 1.15 1.4 2009 1.16 July 1.08 1.1 2010 1.25 March 1.09 1.1 Average 1.2 Minimum 1.0 Maximum 1.4 The population projections used in this report are conservative and they utilize the methodology presented in the CAR. Consequently, the estimated flows from 2021 through 2028 are also conservative reflecting the impact of these population projections. The AADF values from 2021 through 2028 were obtained using population projections and the average flow per capita obtained from the CAR. The projected maximum three (3) month AADF for 2028 is 1.75 which meets the permitted capacity of 1.8 MGD for the water reclamation facility. In the CAR, linear regression was used to extrapolate when the facility would reach the permitted capacity of 1.8 MGD based upon population estimates and projected flows. This estimate is confirmed in this report. The reuse water distribution is permitted for 1.45 MGD based upon AADF values. If the water reclamation facility sends all of the effluent for reuse storage and distribution then the projected maximum three (3) month AADF value of 1.75 MGD would exceed the permitted limit. This projection confirms the need for the construction of a reuse water storage tank.

The original wastewater treatment facility (WWTF) was constructed in the late 1960’s. At present, the sludge holding tank, filtration/chlorination/maintenance building, and the oxidation ditch remain from the original plant construction. The WWTF was upgraded and expanded to 1.8 MGD in 1995. This expansion effort upgraded the WWTF to a 5-stage biological nutrient removal (BNR) process whose discharge meets the FDEP criteria for public access reuse of the reclaimed water. A previous engineering study had determined that full reuse of the treated effluent within the City of Cape Canaveral was not financially feasible. This conclusion combined with the state requirement to cease discharge to the Banana River left the City with little to no options with respect to effluent disposal. However, in 1994, the City was approached by the City of Cocoa Beach to pursue an inter- local agreement to transfer treated effluent to supplement the City of Cocoa Beach's reclaimed water supply. This request for 750,000 gallons per day of reclaimed water on an annual average daily basis finally made a reclaimed water system feasible for the City of Cape Canaveral. Thus the City currently discharges its reclaimed water to the nearby City of Cocoa Beach, and its own city-wide reclaimed water distribution system. Any remaining surplus reclaimed water is discharged to the Banana River. The 1995 expansion of the WWTF included a new pretreatment facility, an activated sludge process tank No. 1 (anaerobic, anoxic and equalization tanks), upgrade of the oxidation ditch including an internal recycle pumping system, upgrade of an existing tank to the activated sludge process No. 2 tank (second anoxic and reaeration tanks), two secondary clarifiers with associated return and waste sludge pumping systems, three tertiary filters, two chlorine contact tanks, effluent pumping station with dechlorination facilities for surface water discharge, a 1.0MG reclaimed water storage tank and pumping system, a 1.4MG reject effluent storage tank, a sludge holding tank and a sludge dewatering facility. In addition, an operations building was constructed (Condition Assessment for the Cape Canaveral Wastewater Treatment Facility, June 2006, Brown and Caldwell). In 2005, additional upgrades were made including the construction of additional reclaimed water pumps, a cover on the 1.4MG reject storage tank to allow this tank to also serve as reclaimed water storage, piping and automatic valving to allow the equalization tank to serve as reject effluent storage, a sodium hypochlorite storage and feed system to allow the City to discontinue the use of gaseous chlorine (Condition Assessment for the Cape Canaveral Wastewater Treatment Facility, June 2006, Brown and Caldwell).

As indicated by the Process Flow Diagram of Figure 3.2, the biological process is preceded by mechanical screening of the raw wastewater influent and plant return flows followed by vortex grit removal by a JETA grit removal unit with an associated grit classification unit. These units remove the larger undissolved debris and much of the sand from the influent flows. Flow splitting between the treatment train and a flow equalization tank also occurs ahead of the biological process through the use of a splitter box and a 0.4MG flow equalization tank. The flow equalization tank also provides some of the facility’s capacity for storage of substandard effluent. The BNR process follows the screening, grit removal and flow splitting. It includes two anaerobic basins (fermentation basins), two anoxic treatment basins, a single aeration basin (oxidation ditch), two second anoxic basins and two re-aeration basins. Except for the lack of a second aeration basin, the process would act as two independent parallel trains. Following the BNR process, flow is pumped to two clarifiers acting in parallel where biomass is separated from the effluent flows. Those flows are piped to three Parkson Dynasand filters acting in parallel which then discharge to the two chlorine contact tanks where chlorine is added for the disinfection of the filtered effluent to meet the standards of High Level disinfection per Rule 62- 600.440. Following chlorination, flows are pumped to the facility’s 1.0MG reclaimed water storage tank. Additionally, the 1.4MG storage tank is utilized for reclaimed water storage which limits its use as a substandard flow storage tank. The biosolids removed from the clarifiers is either returned to the influent splitter box to mix with the facility influent or diverted to the 0.17MG sludge holding tank as appropriate to maintain the solids inventory of the facility. Biosolids in the sludge holding tank are aerated and then pumped for dewatering by the facility’s single belt filter press. The belt filter press combines the thickened biosolids from the digester with a polymer and then essentially squeezes out the water to produce a “cake” that is approximately 16% solids. This cake is accumulated and then disposed of in a landfill. A more detailed discussion of each component of the treatment facility and its ancillary components is available in the 2011 Capacity Analysis Report by TetraTech or the 2006 Condition Assessment by Brown & Caldwell. City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 3-5 February 2013 3.2.1 Influent and Effluent Data As previously indicated, the facility produces a permitted discharge that does not surpass the FDEP criteria for public access reuse of the reclaimed water. This discharge is permitted under the facility’s FDEP Florida Domestic Wastewater Facility Permit (Permit Number FL0020541) up to 1.45MGD annual average with an alternate discharge to the Banana River permitted at up to 0.99MG annual average. As discussed in Section 2.72, the facility is operating well within its permitted wastewater discharge parameters and well below its permitted flows. In fact, very conservative population projections included in the report do not show the facility exceeding its permitted capacity until 2028. The population estimates presented in the CAR and extrapolated from 2021 through 2028 are higher than might be expected given the actual U.S. Census population recorded in 2010. The flows estimated in this report do approach the permitted threshold of 1.8MGD AADF. The flows calculated are directly correlated with the conservative population estimates for each year. Therefore, existing process treatment levels and capacity are expected to be adequate for a planning period of twenty years (2008 through 2028). Since the proposed facility modifications would not alter the treatment process, capacity, or levels of treatment; the primary goal associated with the discharge criteria is to maintain the existing level of treatment while addressing the facility’s physical shortcomings. This establishes the design parameters for any proposed process modifications as the existing discharge parameters. For the surface water discharge to the Banana River, the parameters of primary interest are the CBOD5, TSS, Total Nitrogen and Total Phosphorus which may not exceed 6.25, 6.25, 3.75 and 0.62 mg/L respectively on a monthly average basis. The FDEP Wastewater Facility Permit also presents annual average, weekly average, and single sample limits for these parameters and these values are also presented in the Capacity Analysis Report. The permit places less stringent limits on CBOD5 for discharge to the reclaimed water distribution system at 20, 30, 45, and 60mg/L for the annual average, monthly average, weekly average and single sample results respectively. The TSS has a more stringent limit of 5mg/l for any single sample. Both discharges have chlorine residual requirements of 1.0mg/l residual after disinfection with the surface water discharge being limited to 0.01 residual prior to discharge to the river. Again, as the contemplated changes to the system would not be expected to impact these treatment levels, these parameters are provided primarily to establish the context of the design options. 3.2.2 Goals of Improvements In the preceding discussion of the facility configuration, it should be noted that all the process critical treatment components of the facility occur in multiples with the exception of the single aeration basin or oxidation ditch and the single belt press. The availability of a parallel treatment unit could reduce the potential for discharge of substandard effluent if a failure in the aeration basin occured. Also, failure of its mechanical components would result in a rapid degradation of the facility’s treatment ability and if not corrected within a day or two would also result in the discharge of partially treated effluent into the Banana River. This situation is compounded by the fact that the City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 3-6 February 2013 1.4M storage tank is currently being used routinely for reclaimed water storage and the 0.40MG substandard effluent tank is also serving as the influent equalization tank. This aspect is discussed in later sections. The existence of only a single belt filter press is less problematic in that it is a mechanical unit which can be readily accessed and its flows may be shut off to allow repairs. In that case, solids can be accumulated within the treatment facility for a few days or they could be trucked off site for treatment at an alternate facility. However, neither measure is desirable. The accumulation of solids within the facility would tend towards upsetting the treatment process and would degrade the reclaimed water quality over time. Alternately, the trucking of liquid biomass to alternate facilities for treatment would be very expensive and could not be financially supported for significant periods of time. In order to minimize the possibility of discharging substandard effluent associated with the aeration basin failure or the belt filter press failure, the City of Cape Canaveral wishes to pursue the following remedies: 1) Provide a parallel redundant path of treatment to the existing single aeration basin. 2) Provide an alternate biosolids dewatering system or minimize the potential for problems with the existing singe belt press. City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 3-7 February 2013 3.3 Reuse Water Supply As indicated in previous sections, the effluent from the City of Cape Canaveral WWTF meets the FDEP permit requirements for unrestricted public access reuse under the Rule 62-611. Therefore, the reclaimed water from the facility is considered by the City to be a commodity with value. Accordingly, the City has developed a reclaimed water user base to maximize the value of the reclaimed water and ensure a reliable demand for the reclaimed water to minimize the need for the use of the alternative surface water discharge to the Banana River. In the mid 1990’s, lacking an established residential customer demand for the reclaimed water, the City of Cape Canaveral entered into an interlocal agreement with the City of Cocoa Beach whereby for a twenty year period Cape Canaveral supplied Cocoa Beach with up to 750,000 gpd on an annual average basis of reclaimed water at no cost. Since December 1996, this agreement has provided Cape Canaveral with a reliable demand for a large portion of its reclaimed water. In the meantime, Cape Canaveral has developed its reclaimed water customer base throughout its service area and has recently instituted a rate structure for the delivery of reclaimed water to its customers excluding Cocoa Beach. The anticipated revenues from this rate structure are now an integral component of the City’s financial statements starting at $165,900 annual income in 2012/13 and growing by 2015/16 to $192,400 according to the Cape Canaveral Sewer System Rate Study February 2012 prepared by Raftelis Financial Consultants, Inc. The development of the reclaimed water customer base has progressed to the point that demand now routinely outstrips available supply and reclaimed water is now only made available six days a week. The elements of the reuse system include the storage and pumping components located at the treatment facility, the transmission main to Cocoa Beach and the distribution system throughout the City of Cape Canaveral. At the treatment facility, the reuse components include a 1.0MG storage tank dedicated to reclaimed water storage and a set of reclaimed water pumps which act to pressurize the reclaimed water system on operating days. Additionally, the City has utilized its 1.4MG storage tank primarily for reclaimed water storage. Off site, the reclaimed water distribution system consists of a network of distribution mains throughout the City ranging in size from 4 inches through to 16 inches in diameter. The distribution does not have any off-site reclaimed water storage. 3.3.1 Flow and Usage Data As previously indicated, Cape Canaveral and Cocoa Beach are operating under an interlocal agreement which gives Cocoa Beach first rights to up to 750,000 gpd of reclaimed water from Cape Canaveral. As indicated by Figure 3.3, these flows represent a significant component of the reclaimed water available from Cape Canaveral. Additionally, due largely to unavailability of reclaimed water storage, Cape Canaveral has been forced to discharge significant quantities of reclaimed water to Banana River as also illustrated by Figure 3.3. If the City were to keep the water sent to Cocoa Beach and to the Banana River in storage tanks, additional revenue could be generated by transmitting reuse water to existing customers. Using the newly enacted 2012 reclaimed water flat rate of $6.33 per month per ERIC (Equivalent Residential Irrigation Customer) effective October 1, 2012, allowing 5,000 gallons per month per ERIC, and assuming a realization of 80%, these City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 3-8 February 2013 projected revenues would average approximately $95,000 per year from 2009 through 2011 using data found in the FDEP Monthly Operating Reports. It is also possible that additional costs could be incurred establishing transmission lines to new customers.

However, in practice, the tank is routinely used for reclaimed water storage thus limiting its availability for emergency storage. This dominant use of the 1.4MG tank for reclaimed water storage reduces the facility’s available substandard water storage to that of the 0.40MG influent flow equalization/substandard water storage tank. As indicated by its name, this basin is also configured as a dual-use basin. Therefore, during periods of high flow, the capacity of this basin is at least partially utilized in the role of influent flow equalization thereby further reducing the available storage capacity for substandard effluent. City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 3-9 February 2013 Concurrent with the challenges associated with the unavailability of substandard effluent storage capacity, the City is missing the opportunity to maximize its sale of reclaimed water to its paying customers. As indicated in the previous section, significant quantities of reclaimed water are either being sent to Cocoa Beach or to the Banana River. These reuse water flows represent a potential revenue source for the City of approximately $95,000 per year as stated in Section 3.1.1. Meanwhile, the use of the City’s reclaimed water customers is being limited to six days a week due to the lack of availability of reclaimed water. Finally, with the Banana River being used as a backup discharge location for the reclaimed water not used by Cape Canaveral customers or by Cocoa Beach, the regulatory authority of discharging to a surface water body must be considered. In this context, statewide trends to limit or eliminate surface water discharges are likely to be enacted by regulatory agencies in the future. Thus the long term viability of current permitted discharging of reuse water to the Banana River should be considered tenuous and is likely destined to be limited or possibly ended. With the expiration of the interlocal agreement with Cocoa Beach set at December 31, 2016, the City has an opportunity to regain control of the reclaimed water previously dedicated to Cocoa Beach. With the recent enactment of a user fee to the Cape Canaveral reclaimed water users, the City also has an opportunity to maximize its revenue stream and also to minimize the discharge of reclaimed water to Banana River. Finally, the City needs to regain the use of its 1.4MG tank to be primarily for substandard flow storage to minimize the possibility of a discharge of substandard effluent. In order to take advantage of these opportunities, the City must upgrade its reclaimed water system to maximize the availability of reclaimed water to its paying customers. In order to regain the substandard flow storage volume, the City must increase the available storage volumes for either reclaimed water or for substandard water. Based upon the preceding discussion of the facility’s configuration and the examination of the site and system components, the addition of reclaimed water storage will both meet the need for more substandard water storage and maximize the availability of reclaimed water to the paying customers of Cape Canaveral. City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 4-1 February 2013 4 PROPOSED WASTEWATER AND REUSE PROJECTS 4.1 General As presented in Section 3, three areas of the wastewater treatment system and the reclaimed water distribution system threaten the ability of the facility to reliably maintain the required levels of treatment with the redundancy as appropriate for their level of service. This section presents the identified options for the resolutions of those circumstances determined to be the most cost effective approaches. Additionally, the Holman Road Sanitary Sewer Improvements is presented as a proposed component of the project. The presented options address the needs for each of the identified project areas along with a qualitative comparison and a presentation of their associated cost considerations. Following this presentation of the evaluated options, Section 5 presents the recommended option along with additional information related to that option. 4.2 Oxidation Ditch Reconfiguration As concluded in Section 3.2.2, the existence of a sole aeration basin within the treatment train where all other processes are divided among redundant basins is undesirable. Therefore, the proposed project will provide a parallel redundant path of treatment to the existing single aeration basin. Examination of the existing wastewater treatment plant site indicates that there is not a readily available location for an additional aeration basin. The remaining open area on the west side of the plant is not easily accessible without the addition of intermediate pumping and this location is also needed for additional reclaimed water storage as discussed in later sections. Additionally, the site is essentially surrounded by water on three sides and a City Park on the fourth (north) side. Therefore, the construction of an additional aeration basin would require the displacement and relocation of existing facilities off site which could include an incursion into the adjacent City Park. Finally, from a process perspective, addition of another aeration basin without a corresponding addition in flows could actually result in degradation of the treatment since the necessary carbon source of raw sewage to maintain the biological mass in two basins would not be adequate and the basins would basically be starved if run in parallel. Therefore, the addition of a second aeration basin to operate in parallel to the existing basin would need to be accomplished through the reconfiguration of the existing basin into two independent basins. There are at least three viable options to accomplish this reconfiguration which are presented in the following subsections. With the focus narrowed to the modification of the existing aeration basin into two basins, the evaluation examined three alternatives for the aeration of the reconfigured basin along with their respective structural and piping modifications. Additionally, conceptual level sequence of construction considerations were included in order to capture the costs of temporary measures as required to implement the reconfiguration. These elements were examined to identify the most cost effective means to maintain process treatment capacity while providing the desired aeration zone redundancy. In this option evaluation, the specific aeration basin improvements that were evaluated for process redundancy include tank structural modifications and aeration system modifications. City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 4-2 February 2013 Ancillary mechanical improvements (piping, weirs) were also considered, but the primary focus was the structure itself and the type of aeration. The three options for aeration of the reconfigured basins identified as the basis for comparison are: Option 1 – Aeration Basin Split Lengthwise with Surface Aeration Option 2 – Aeration Basin Split Lengthwise with Diffused Aeration Option 3 – Aeration Basin Bisected across Its Long Axis with Surface Aeration Conceptual layouts of these options are enclosed with this plan as Figure 4-1, Figure 4-2 and Figure 4-3. These options were compared as it relates to the benefit of the improvements associated with their initial capital costs, the constructability and down time of each option, and generally the long- term benefit of either option. 4.2.1 Option 1 – Aeration Basin Split Lengthwise with Surface Aeration Option 1 entails the removal of the existing aerators and associated steel bridge and the installation of two replacement aerators along with FRP (Fiberglass Reinforced Plastic) covers over the splash zones around the aerators. It also includes the reconfiguration of the southern end of the aeration basin to divide it into two independent basins and the modification of the center wall to have sufficient strength to support the hydrostatic loads of only one basin being full of water. Finally, it includes the modification of the influent gallery, recirculation piping, and discharge piping to accommodate the two independent basins. This configuration results in two long parallel aeration basins able to act independently from the other. 4.2.2 Option 2 – Aeration Basin Split Lengthwise with Diffused Aeration Option 2 entails the removal of the existing aerators and associated steel bridge and the installation of two independent fine-bubble air diffuser systems supplied by blowers in a new blower building. It also includes the installation of propeller mixers to provide a mixing along the length of the basins with their associated access bridges. The included structural modifications consist of the reconfiguration of each end of the aeration basin to divide the basin into two independent basins and the modification of the center wall to have sufficient strength to support the hydrostatic loads of only one basin being full of water. Finally, it includes the modification of the influent gallery, recirculation piping, and discharge piping to accommodate the two independent basins. This configuration also results in two long parallel aeration basins able to act independently from the other with the difference being the means of aeration. City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 4-6 February 2013 4.2.3 Option 3 – Aeration Basin Bisected across Its Long Axis with Surface Aeration Option 3 is similar to Option 1 in that it retains surface aeration with FRP covers over the splash zones around the aerators. However, the geometry is different in that this option divides the basin across the midpoint of its long axis to result in two shorter basins located end-to-end. This configuration will also require two additional aerators but all four aerators will be of a lower horsepower than the existing aerators. This configuration minimizes the required construction of hydrostatic walls to the single bisecting wall and thus provides for a shorter construction period. Finally, it includes the modification of the influent piping geometry to include a splitter box, and addition of recirculation piping and discharge piping to accommodate the second basins. 4.2.4 Comparative Analysis In the evaluation of the options, there are differences between the options which impact the cost of the project. Additionally, there are differences which are more qualitative but should also be a consideration. Both sets of distinguishing considerations are summarized as follows through a listing of each option’s advantages below. Additionally, the common aspects of each option are indicated to reflect that they have been evaluated. Common Aspects: • It will be necessary to completely empty the aeration basin to allow for the construction. • Under Options 1 and 2, the existing influent box will be modified to include a port to the western basin and influent control gates on both basin influent ports. Option 3 includes an external splitter box for the northern and southern basins. • An effluent weir and discharge pipe will be added to the second basin • An internal recycle suction pipe will be added between the new basin and the recycle pumps. • The internal recycle pumps will be repiped to dedicate two pumps per aeration basin with valving to allow cross feeding. Option 1 Advantages (Split the Aeration Basin Lengthwise with Surface Aeration): • Lower construction cost than Option 2 (about equal to Option 3). • Fewer changes to the existing ditch process than Option 2. • Familiarity and comfort level of City Staff with mechanical surface aeration. • This option occupies only a small amount of additional plant space in a currently unused area south of the basin. Option 2 Advantages (Split the Aeration Basin Lengthwise with Diffused Aeration): • A slightly shorter reconfiguration period than Option 1 requiring a shorter temporary treatment system and bypassing program (takes longer than Option 3). • A slightly increased process efficiency with a higher oxygen transfer rate providing greater operational flexibility limited by the shallow side-water depth of the existing basin. Option 3 Advantages (Bisect the Aeration Basin across Its Long Axis with Surface Aeration): City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 4-8 February 2013 4.3 Sludge Belt Refurbishment As with the aeration basin, Section 3.2.2 concluded that the reliance a single belt filter press to process biosolids is undesirable in that its failure would cause a significant hardship on the operation of the treatment facility or result in significant additional costs. Therefore, the identified goal is to provide an alternate biosolids dewatering system or minimize the impact of the existence of the existing singe belt press. In evaluation of available approaches to meet this goal, the options identified are as follows and discussed in greater detail in the following subsections: Option 1 – Add a second belt press in parallel to the existing unit. Option 2 – Replace the existing belt press with two smaller dewatering units. Option 3 – Retain the existing unit as a single unit and minimize its failure likelihood through its complete rebuilding using manufacturer approved methods and parts. 4.3.1 Option 1 – Add a Second Belt Filter Press to Match the First Under this option, the existing 2-meter belt press would be retained in service without modification and a second new system would be installed to provide complete redundant dewatering capacity. Due to the configuration of the existing system, its building is not practically expandable to accommodate a second unit. Therefore the new unit would be located remote from the existing unit. Given the site availability limitations as discussed in other sections of this plan, this new unit would need to be squeezed into the area just north of the proposed reclaimed water tank as discussed in Section 4.4. However, this location would not allow a pull-through operation of the cake hauling trucks and would represent a less desirable situation. In addition to the construction of a new belt press building and the addition of a new 2-meter belt press, the existing belt press will remain in service. This will require the refurbishment of the existing belt press building to address accumulating signs of age. The refurbishment would include the replacement of selected components of the building such as doors and electrical fixtures along with minor repairs as needed. In theory, the availability of two equally sized units would double the dewatering capacity of the facility. However, in practice, the dewatering capacity above that needed for daily operations is not used. One unit usually gets the bulk of the use while the other sits idle as a backup unit. Therefore, the addition of a new 2-meter unit primarily serves to increase the available redundancy of the existing system at a cost of increased maintenance as required to keep both units operational. 4.3.2 Option 2 – Replace the Existing Press with Two Smaller Units This option would dismantle the existing belt press installation and replace it with a system of two independent dewatering systems. Those systems would each include a 1-meter belt press, a polymer dosing system, a sludge pump, and cake storage and loading components. This system being sited at the location of the existing facility would allow for the pull-through operation of the cake hauling trucks. This option results in a capacity matching the existing but with a greater level of redundancy City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 4-9 February 2013 and thus reliability. Should one unit go out of service, the remaining unit can be more heavily utilized while the first unit is repaired. 4.3.3 Option 3 – Retain and Rebuild the Existing Unit This third option would retain the existing facilities in their current configuration without the addition of new capacity. Instead, it would minimize the likelihood of a debilitating dewatering system failure through the complete refurbishment of the existing system. This refurbishment would utilize manufacturer authorized service personnel to essentially replace all belt press components subject to wear. Additionally, those components subject to and showing any signs of corrosion would be either refurbished or replaced if the level of corrosion warranted. Finally, the ancillary components such as the polymer feed system would be individually evaluated for remaining service life and replaced as appropriate or uninstalled spares would be provided. Essentially, the resulting system would be a fully refurbished system. This option would also include the refurbishment of the building except to a greater degree than that of option 1 to reflect the singular reliance upon the one belt press. That refurbishment would include most or all of the electrical fixtures and doors along with other building repairs and repainting as appropriate to significantly extend the working life of the building under a full-time operating environment. 4.3.4 Comparative Analysis These options were compared in terms of complexity, provided level of service, construction interference with ongoing plant operations, and generally the long-term benefit of the options. Cost comparisons are evaluated separately in a subsequent section. Below, the common aspects of each option are indicated along with the relative advantages and disadvantages of each option. Common Aspects: • Each option will maintain at least the current dewatering capacity which historically has been more than adequate. • Each option relies upon belt press technology which is familiar to the plant operating personnel. Option 1 Advantages and Disadvantages (Add a Second Belt Filter Press to Match the First): • Advantage: Does not require any significant disruption of the existing system for installation. • Advantage: Provides a completely new unit providing 100% redundancy to the existing unit. • Disadvantage: Accessibility is limited by site restrictions precluding the desirable pull- through truck operation. • Disadvantage: Mechanical complexity is double requiring greater maintenance attention. • Disadvantage: Facility location west of the existing system will involve greater disruption of the site during construction. • Disadvantage: The greater redundancy provides significantly more capacity than is needed thereby requiring greater number of starts and stops or longer down times for the equipment which both accelerate component degradation. City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 4-12 February 2013 4.4.1 Option 1 – Storage within the Distribution System In examining the options for placement of the desired additional storage, the lack of availability of property at the treatment facility is a limiting factor. Essentially, the addition of a new reclaimed water storage tank will occupy most of the available property. Therefore, the placement of the reclaimed water storage tank off site should be examined as an option. Under this option, property would be acquired remote from the plant site and a tank would be built there. Assuming a ground storage tank is constructed, it would be filled from the existing distribution system through a pressure bleed valve during low demand periods and then accumulated flows would be pumped into the system during high demand periods. A ground storage tank is presumed alternative due to the relatively higher cost of an elevated tank and its susceptibility to hurricane damage in this coastal area. By examination, this option will be significantly more complicated and expensive than placement of a tank at the treatment facility. The purchase of property remote from the treatment facility would be costly and would potentially meet with significant public opposition. Additionally, the need to pump the flows back into the system during low demand periods would require new pumping facilities with a SCADA control system along with the tank. This increases the capital costs, the project complexity and the long term operating costs. 4.4.2 Option 2 – Additional Storage within the Wastewater Treatment Facility Site As indicated, the property of the existing wastewater treatment facility is essentially built out with the exception of the western side of the plant in the area of the abandoned sludge drying beds. Therefore, this option proposed the construction of a ground storage tank for reclaimed water storage in the area previously occupied by the sludge drying beds. This area allows for a tank of no greater than 120 feet in diameter. This option would include the extension of the existing reclaimed water piping to and from the proposed tank to allow it to function in tandem with the existing 1.0MG tank and be served by the existing influent and high service pumps. Ideally this option would also include a tank configured to match the hydraulic profile of the existing 1.0MG ground storage tank with an operating depth of 14.17 feet. However, the available 120-foot diameter footprint would only have a total capacity of 1.2MG which is well short of the recommended 3.0MG minimum capacity as determined previously in this section. In order to provide the recommended tank capacity with a 120’ diameter, the tank side water depth of 35’-6” is required. In order to accommodate this taller tank, automatic valving will be required to allow it to function in parallel to the existing 1.0MG tank. This valving would likely include a float-actuated valve on the 1.0MG tank to preclude its overfilling along with a check valve on its discharge to preclude backflow through the discharge pipe from the new tank into the existing tank. City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 5-1 February 2013 5 SELECTED WASTEWATER AND REUSE ALTERNATIVES 5.1 Oxidation Ditch Reconfiguration In the preceding Section 4, three viable options were presented for the division of the existing aeration basin of the Cape Canaveral WWTF into two independently operating basins with the intent to increase the facility reliability by eliminating the lack of redundancy in a critical component the treatment process. Based upon the comparative evaluation of the three options along with consideration of the capital cost and present worth costs of each alternative, Option 3, the Bisection of the aeration basin across its long axis with Surface Aeration, is recommended as the proposed project. The following subsections will more fully describe the proposed project scope including the presentation of a phasing plan as a proof of concept. Additionally, the environment impacts of the project will be discussed along with associated mitigation measures. Finally, the previously presented comparative opinion of probable costs will be re-examined and design phase variables that may influence the cost will be identified. 5.1.1 Description Option 3 entails the reconfiguration of the aeration basin to divide it into independently operating northern and southern basins through the installation of a hydrostatic wall across the long axis of the basin at approximately its mid point. The reconfiguration will include the replacement of the existing aerators on the northern aeration basin with smaller aerators along with the installation of matching aerators on the southern basin. FRP (Fiberglass Reinforced Plastic) covers will be installed over the splash zones around the aerators to minimize aerosol releases from the basins. The existing influent flows will be split between the two basins through the addition of a splitter box just west of the basins. The effluent flows from the southern basins will be piped to intercept the existing discharge pipe where isolation valves will be added to allow for routine maintenance of either discharge box. In order to provide for the required Internal Recycle (IR) of flows from the new basin, an IR pipe will be run from the new basin to the existing IR pumps. The piping of these pumps will be reconfigured to dedicate two pumps to each aeration basin thereby allowing their independent recycle flow rate control. This proposed construction is reflected by Figure 4.3 as previously presented in Section 4. 5.1.2 Phasing The following discussion is offered to expound upon the constructability challenges of the proposed option. As previously indicated, the proposed construction will require the dewatering of the existing aeration basin for a period of time. Additionally, the piping modifications required will necessitate the interruption of other aspects of the treatment system for shorter periods of time. The accommodation of this requirement through the sequencing of construction and the provision of temporary treatment facilities will be of paramount importance to the successful and cost effective City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 5-2 February 2013 completion of the project. Therefore, it will be important to develop a plan that is practically feasible, communicated to and approved by the FDEP Central District and will allow the City Operations Team the highest probability of meeting the effluent discharge limits during construction. Accordingly, the outlined Sequence of Construction (SOC) as Figure 5.1 is included as a “Proof of Concept” to illustrate the validity of the proposed approach and the resulting inclusion in the opinion of probable costs. This SOC also proposes several alternatives for the temporary repurposing of existing tankage for use as an alternate aeration basin during the required outage of the existing aeration basin. In developing the SOC and the proposed work scope, it was recognized that the division of the existing aeration basin must include the installation of a hydrostatic wall (a wall sufficiently strong to withstand the forces of water only on one side). This wall is key to the operation of the two basins independently and allows for the dewaterering of either basin without disruption of the other basins operations. It is also key to the minimization of temporary flow measures as it allows construction to be ongoing within either the north basin or the south basin while the other is in service. However, the hydrostatic wall installation will require the dewatering of the entire aeration basin for a period of time. Additionally, the addition of an influent splitter box will require the influent pipe to be dry for a short period of time. These two components are the focal accomplishments of the first phase of the proposed construction as illustrated in Figure 5.2. The other modifications of the aeration basin including the installation of turning vanes and fillets to maximize mixing, construction of a second effluent weir gate, addition of internal recycle and effluent piping, installation of new surface aerators all can be performed sequentially in dry basins. Each of these modifications is anticipated and programmed into the SOC as phases 2, 3 and 4 so as to minimize the required downtime of the aeration basin. In regards to the provision of an alternate treatment aeration basin to allow the dewatering of the aeration basin, BDI examined several alternatives and discussed the current tankage uses with the plant operating personnel. Based upon this effort, two alternatives were identified for consideration. One consideration is to bypass the aeration basin and convert a portion of the 2nd Anoxic Tank to an aeration zone through the addition of an interim method of aeration. The 2nd Anoxic Tank could be operated in a phased approach similar to a Sequencing Batch Reactor (SBR) process in which the City could provide multiple phases of aerobic/anoxic treatment within that one basin. To accomplish this and achieve the removal levels required by the permit, City staff would need to control the timing and volume of air sent to the basin based on DO levels in the tank. This is not a perfect solution but could be considered an interim measure that would allow the City to operate near permit effluent levels. A second alternative is the temporary repurposing of the existing 1.4MG storage tank west of the 1st Anoxic Basin to be an aeration basin. This repurposing could be accomplished though the temporary repiping of the transfer pump discharge from the 1st Anoxic Basin into this tank and the piping of a temporary discharge to the existing 2nd Anoxic Basin. Additionally, provision of a temporary diffused aeration system in the tank would be required along with recirculation of the City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 5-4 February 2013 clarified sludge return to this tank. As this alternative allows for the steady state operation of the tank aeration and preserves untouched the capacity of the remaining tanks, it is proposed to be the alternative of choice and is therefore included in the opinion of probable cost for this element of the project. 5.1.3 Environmental Benefits As indicated in Section 2, the primary benefit of the proposed aeration basin modification is the creation of a redundant flow path where there currently is none. Therefore, the primary benefit of the project is that a failure of one of the flow paths will not cripple the ability of the facility to keep treating its flows. Historically, the oxidation ditch configuration that is employed at Cape Canaveral is able to absorb large fluctuations in its flow rates without a significant degradation of its treatment quality. By providing an alternate flow path, the treatment level even through only one aeration basin would be expected to remain high. This approach reduces the likelihood of a discharge of substandard flows if an aeration basin fails. 5.1.4 Adverse Impacts and Mitigation With the selection of the identified option, the footprint of the aeration basin remains unchanged and all proposed construction remains within the existing facility perimeter. Therefore, the only likely environmental impacts associated with the project are the temporary construction related impacts and the operational impacts of the completed facility. Temporary construction impacts would normally include polluted stormwater runoff from disturbed earth and the actual noise from construction activities. In this case, the proposed construction outside of the existing basin will mostly be relatively small amounts of piping and the influent flow splitter box construction. These activities will disturb only a small percentage of the existing site. To mitigate their possible impact, the construction contractor will be required to obtain the required NPDES permit for construction activities and to implement Best Management Practices for the minimization of stormwater runoff impacts. As to mitigation of the noise associated with the construction, the contractor will be limited to working during standard business hours except in cases of emergency or completion of operations that must be continuous and last beyond a normal work day. The latter occurrence is not expected on this project as there are not any large concrete pours that typically need to be continuous. The operational impacts of the project would be the possible odor and aerosol mist generated by the operation of the aerators. As previously indicated, FRP covers of the splash zones will be included in the project scope to minimize both potential discharges. Historically, this oxidation ditch configuration with the covers has not produced noticeable odor or mist problems. Therefore, the proposed covers would be considered as adequate preventative measures. City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 5-7 February 2013 ancillary mechanical components will each require detailed evaluations as a prerequisite to their inclusion in the replacement list. 5.3 3 MG Reclaimed Water Tank As discussed in Section 4, the addition of a 3.0MG reclaimed water storage tank at the wastewater treatment facility is heavily favored over the possibility of adding storage within the distribution system. This reflects the difficulty of obtaining property for a remote tank plus the significant added costs of repumping and controls at a remote site. Therefore, the addition of the tank at the WWTF is recommended as the proposed project. 5.3.1 Description The scope of work for the addition of the 3.0MG reclaimed water storage tank at the WWTF includes a compete 120-foot diameter prestressed concrete domed storage tank with side water depth of 35-foot 6-inches and all associated accessories such as ladders, hatches and vents. Additionally, the connecting piping to the influent and discharge piping of the existing system is required. Since the property constraints require the proposed tank to be taller than the existing tank, a float valve on the existing 1.0MG tank is required to keep it from overfilling while the new tank is still filling. The float valve would most likely be in the form of an electrically actuated valve initiated by a float or a signal from a transducer. Additionally, a check valve on the discharge piping of the existing 1.0MG tank should preclude it from filling up by water backflowing from the 3.0MG tank. Finally, the associated electrical devices, lightning protection system, and SCADA reprogramming would be included with the tank. With the construction as described, the dual use of the 1.4MG tank would be discontinued and that tank would again be dedicated to substandard water storage. 5.3.2 Phasing Since the existing system has alternate discharge points available, the phasing of the proposed work is relatively simple. The new tank and much of its piping could be constructed without interruption of the existing system. A short interruption in the use of the 1.0MG tank would be required. This interruption would probably require the use of the 1.4MG tank as reclaimed water storage for a short time. Therefore, this use would have to be coordinated with the aeration basin improvements such that the 1.4MG tanks need is not simultaneous. 5.3.3 Environmental Benefits As indicated in Section 3, identifying the need for the tank, the existing 1.4MG storage tank is currently occupied by its service in storage of reclaimed water. Therefore, the WWTF has little or no capacity for the storage of substandard effluent. So, the environmental benefit of the proposed tank is the recapture of the 1.4MG capacity for substandard flow storage. This storage provides nearly a full day of storage of flows to allow the facility operators to correct problems in the treatment system before substandard flows would be released to the environment. This tank also promotes the reuse of reclaimed water for irrigation purposes rather than using the Banana River as a receiving water City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 6-1 February 2013 6 EXISTING STORMWATER SYSTEM 6.1 General In 2000 the City had a Master Stormwater Plan developed. The background information and existing condition data presented here was largely obtained from that report. A major concern for the City’s stormwater system is the excessive discharge of nutrient-rich waters into the Banana River and the associated turbidity with these discharges. Stormwater runoff degrades the water quality in the Banana River by both diluting the Lagoon’s salinity with fresh water and by adding excessive nutrients and suspended solids. The Clean Water Act in the early- 1970s helped to reduce industrial and wastewater discharges, but did little to address the widespread pollutant loadings from storm sewer systems. In the late-1970s, the SJRWMD began requiring that private developments retain a portion of their stormwater runoff on-site. More recently, the EPA passed legislation (NPDES program) that enforces strict stormwater regulations on city and county governments. Additional regulations from FDEP have established pollutant Total Maximum Daily Loads (TMDL’s) for receiving water bodies. These regulations require city/county governments and other stakeholders to further reduce pollutants in stormwater runoff. During the later 1950’s and through the 1960’s, the City of Cape Canaveral and the Florida Department of Transportation (FDOT) constructed stormwater drainage systems that carried stormwater discharge from State Road A1A to the Banana River, part of the Indian River Lagoon. The stormwater discharge is routed through 54 inch or larger culvert and is ultimately discharged into the Banana River at the following locations: Holman Road, Center Street, International Drive, and Central Boulevard. Additional stormwater discharges occur at the Canaveral Drainage Canal, and the Wastewater Treatment Facility. Non-point or sheet flow drains from City and private lands along the City’s western boundaries; these flows represent small areas and are not concentrated, therefore they represent a minor inflow to the Lagoon. Historically, the City’s drainage system has been able to handle stormwater discharge to minimize flooding within the City, but pollutants contained in the stormwater have been discharged directly into the Banana River. 6.2 City Drainage Basin Delineation Based upon earlier field investigations and data collected, there are seven (7) major drainage basins within the City of Cape Canaveral. These drainage basins delineated in the Cape Canaveral Stormwater Master Plan are shown in Figure 6-1 on the following page. The drainage basins are described starting from the north and moving south through the City’s stormwater service area.

The designs for the development within this drainage basin provided adequate storage for a 100-year storm event. Consequently, there is no stormwater discharge to the Banana River Lagoon that would adversely affect water quality for this protected water body. 6.2.2 Mosquito Drainage Basin The Mosquito drainage basin contains 34 acres ± and is located in the northwest corner of the City adjacent to the Banana River Lagoon. This basin contains wetlands and has mosquito ditches. Zoning within this drainage basin is C1 Commercial. 6.2.3 Canaveral Drainage Basin The Canaveral drainage basin is the largest basin in the City’s stormwater service area with 527 acres ±. Residential zoning within this basin includes R1 Low Density Residential, R2 Medium Density Residential and Townhouse Apartments, and R3 Duplex/Multi-Family/Townhouse Apartments. C1 Commercial and M1 Light Industrial zoning also occur in this area. The primary stormwater outfall for this basin is the Central Ditch, also known as the Canaveral Drainage Canal, which passes underneath State Road A1A and discharges into the Banana River Lagoon. Three (3) baffle boxes at the storm drain underneath West Central Boulevard (53 inches by 84 inches) connect the Central Ditch to the Banana River. In addition to the placement of the baffle box, proposed projects of dredging of the Central Ditch and construction of culverts along the northern portion of the Central Ditch connecting to the baffle box will improve the water quality of stormwater discharge to the Banana River. 6.2.4 Central Drainage Basin The Central drainage basin contains 186 acres ± and the stormwater runoff is conveyed through a 54 inch concrete pipe underneath Central Boulevard and a baffle box east of the outfall into the Banana River Lagoon. Zoning classifications for this basin include R3 Duplex/Multi-Family/Townhouse Apartments, C1 and C2 Commercial, and M1 Light Industrial. 6.2.5 International Drainage Basin The International drainage basin contains 195 acres ± and includes a combination of C1 Commercial adjacent to the State Road A1A corridor and the remaining zoning classifications within the basin are R2 Medium Density Residential and Townhouse Apartments and R3 Duplex/Multi- Family/Townhouse Apartments clustered along the Banana River and Atlantic Ocean shorelines. Stormwater runoff passes through a 66 inch concrete pipe underneath International Drive and passes through a baffle box before it discharges to the Banana River Lagoon. City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 6-4 February 2013 6.2.6 Center Drainage Basin The Center drainage basin contains 154 acres ± and includes a combination of C1 and C2 Commercial zoning adjacent to State Road A1A to the east and west as well as R2 Medium Density Residential and Townhouse Apartments in the interior of the basin area and R3 Duplex/Multi- Family/Townhouse Apartments along the Banana River Lagoon and Atlantic Ocean shorelines. The primary stormwater discharge point is through a 54 inch concrete pipe with a baffle box east of the stormwater outfall at the Banana River Lagoon. 6.2.7 Holman Drainage Basin The Holman drainage basin contains 63 acres ± and includes a combination of R1 Low Density Residential along the Banana River Lagoon and R3 Duplex/Multi-Family/Townhouse Apartments along the southwest corner of the basin adjacent to the Banana River Lagoon. An area with R2 Medium Density Residential zoning is located directly east of the area zoned R3. Along the west side of State Road A1A, the commercial corridor is zoned C1 Commercial. Stormwater discharge flows from a 54 inch concrete pipe that lies underneath Holman Avenue and empties into the Banana River at the stormwater outfall. 6.3 Proposed Projects There are six stormwater improvement projects associated with this plan. These projects include improvements to both conveyance and water quality. Following is a list of the proposed projects and a brief summary of each. 6.3.1 North Central Ditch Improvements-Phase I This project involves dredging and the installation of culverts for the first 400 feet of the northern portion of the Central Ditch north of Central Boulevard. The three (3) 48 inch diameter pipes will be connected to three (3) existing pipes within the baffle boxes located near West Central Boulevard. The ditch bottom requires dredging due to the accumulation of muck and debris over time. Dredging will improve water quality prior to discharge into the Banana River. 6.3.2 North Central Ditch Improvements-Phase II This project involves dredging and the installation of culvert for 400 to 800 feet of the Central Ditch north of West Central Boulevard. Three (3) 48 inch diameter reinforced concrete pipes (RCP) or ADS plastic pipe will be installed. The ditch bottom requires dredging due to the accumulation of muck and debris over time. Dredging will improve water quality prior to discharge into the Banana River. 6.3.3 Central Ditch Dredging City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 6-5 February 2013 This project involves the dredging of the Central Ditch from West Central Boulevard south to the bend towards State Road A1A in order to remove muck and debris that has settled in the ditch. Dredging will improve water quality prior to discharge into the Banana River. 6.3.4 North Atlantic Avenue Improvements Project This project involves the installation of stormwater treatment facilities as part of the construction along Atlantic Avenue of a new pedestrian walkway and installation of new lighting and completion of landscape improvements. The new stormwater facilities will target water quality improvements. 6.3.5 West Central Boulevard Pipe Replacement The existing metal pipe will be replaced or rehabilitated with a pipe of similar diameter. The stormwater in the industrial area north of West Central Boulevard flows through this pipe and much of the northeastern portion of the City would be greatly impacted by the pipe’s failure. 6.3.6 Canaveral City Park-Exfiltration System This project involves installation of an exfiltration system beneath the ball fields to allow stormwater drainage to infiltrate into the surficial aquifer. Stormwater improvements will significantly reduce nitrogen and phosphorous loads discharging to the Banana River. These types of projects will be critical for meeting the requirements of the current Total Maximum Daily Load (TMDL) reduction program. 6.4 Existing Programs The Florida Department of Environmental Protection (FDEP) administers the National Pollutant Discharge Elimination System Program (NPDES) stormwater permitting program in the State of Florida. This program regulates stormwater discharges into surface waters from municipal facilities as well as from industrial and construction activities. The conditions of the NPDES permit require that the City implement strategies for reducing amount of pollutants in stormwater runoff and consequently improve overall surface water quality. The City’s efforts to comply with these regulations include the following programs: • Public Education: requires the City to educate the public concerning stormwater issues. • Public Involvement/Participation: requires that the City involve the public in the stormwater management process. • Illicit Discharges: requires that the City implement a monitoring and enforcement program to identify and eliminate illicit discharges to the storm sewer system. • Runoff Control – Construction Sites: requires that the City monitor and enforce regulations limiting the amount of stormwater runoff from active construction projects. • Runoff Control – Post-Construction: requires that the City continue to monitor and enforce regulations limiting the amount of stormwater runoff from completed construction projects. City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 6-6 February 2013 • Pollution Prevention: requires that the City monitor and enforce regulations concerning the illegal discharge of pollutants to the storm sewer system. • Structured BMP’s include detention ponds, dry ponds, infiltration trenches, baffle boxes, and water quality inlets. Non-structured BMP’s include street cleaning, fertilizer application controls, and certain vegetation practices. In 2003, a Stormwater Utility was established by the City Council in order to ensure that dedicated funds are available for both the management of stormwater runoff and the performance of facility maintenance on the stormwater system. The Stormwater Utility provides the following functions: • Maintain a high level of flood protection through sound planning and service. • Improve and maintain water quality through effective stormwater management strategies. • Maintain infrastructure integrity to protect public safety and private property. • Provide a high level of customer service and communication to the public and private sectors. The City’s current stormwater system is composed of approximately 377 storm drains, six (6) miles of underground stormwater pipe, and six (6) outfall structures (described in Section 6.1). 6.5 Past Projects Table 6-2 below lists the City’s recent and ongoing stormwater projects and maintenance activities. Those that are related to the proposed project are discussed in more detail in Section 7.

City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 7-1 February 2013 7 PROPOSED STORMWATER PROJECTS 7.1 General As presented in Section 6, six stormwater projects have been identified by the City’s Capital Improvements Plan as projects that would reduce the pollutants and nutrient loading of stormwater discharged into the water quality of the Banana River Lagoon and/or alleviate the potential for flooding. This section presents the identified options for the proposed projects using the most cost effective approach for each project alternative. The presented options address the needs for each of the identified project areas along with a qualitative comparison and a presentation of their associated cost considerations. Following this presentation of the evaluated options, Section 8 presents the recommended option along with additional information related to that option. 7.2 North Central Ditch Phase 1 Improvements to the North Central Ditch will expand on a previous project. The City was awarded a grant from FDEP for the installation of three (3) baffle boxes for the removal of total suspended solids, nutrients, heavy metals and debris prior to discharging to the Banana River. Other work included removal of vegetation, excavation of muck from the channel bottom, and stabilization of the channel banks near West Central Boulevard. The project which was completed in 2009 assists with flood prevention, improves water quality of the Banana River Lagoon, and recharges the surficial aquifer. The proposed Phase I improvements to the ditch will extend approximately 400 north of the three baffle boxes. The project area is shown in Figure 7-1. Option 1 of this project involves installation of culverts for the first 400 feet of the Central Ditch north of Central Boulevard. Three (3) new 48 inch diameter culverts will be connected to three (3) existing culverts at the baffle boxes located near West Central Boulevard. The ditch bottom would be dredged to remove accumulated muck and debris prior to the culvert installation. The dredging and new culverts will improve water quality prior to discharge into the Banana River. Option 2 of this project would involve on the dredging of the ditch to remove accumulated muck and debris. 7.3 North Central Ditch Phase 2 The proposed Phase 2 improvements to the North Central Ditch will extend the improvements approximately 400 north of the Phase 1 improvements as shown in Figure 7-2. Option 1 of this project involves installation of culverts along the next 400 feet of ditch north of West Central Boulevard. Three (3) 48 inch diameter culverts will be installed, extending what was installed in Phase 1. As in Phase 1, the ditch bottom would be dredged to remove accumulated muck and debris prior to the culvert installation. The dredging and new culverts will improve water quality prior to discharge into the Banana River.

These water quality facilities would consist of shallow vegetated swales between the curb and sidewalk or behind the sidewalk to capture initial runoff during low intensity events and underground exfiltration trenches to facility percolation of runoff into the groundwater. Option 1 for this project would be to include the treatment swales and exfiltration trenches along with associated demolition/restoration in conjunction with the streetscaping project. Option 2 would be to forgo the treatment swales and exfiltration trenches. 7.5 West Central Pipe Replacement The existing deteriorating metal pipe running along West Central Boulevard from Brown Circle to the Central Ditch will be replaced or rehabilitated with a new culvert of similar diameter. The stormwater in the industrial area north of West Central Boulevard flows through this pipe and much of the northeastern portion of the City could be subject to flooding if the culvert failed and became blocked. The project area is shown in Figure 7-4. Option 1 for this project involves the removal and replacement of the existing deteriorating culvert along West Central Boulevard from Brown Circle to the Central Ditch. This removal and replacement will total approximately 920 feet of 42 and 48 inch culvert. Option 2 for this project involves the rehabilitation of the existing culvert utilizing cured-in-place liner along West Central Boulevard from Brown Circle to the Central Ditch. In addition to the liner installation, spot repairs may need to be made to the existing pipe and manholes may need to be rehabilitated or replaced. The total lining will be approximately 920 feet. 7.6 Central Ditch Dredging This project involves the dredging of the Central Ditch from West Central Boulevard south to the bend towards State Road A1A in order to remove muck and debris that has settled in the ditch. The muck removal will prevent the fine sediments and containments from being re-suspended and discharged into the Banana River. The dredging will also open the flow way, decreasing the likelihood of restricted flows during storm events. The project area is shown in Figure 7-5. Dredging is the only option evaluated for this project. The alternate option would be to take no action and leave the ditch as is. 7.7 Canaveral City Park Exfiltration City of Cape Canaveral, Florida Wastewater/Stormwater Facilities Plan BDI/106804.01 7-5 February 2013 With the City being largely built out, there is very little open land area remaining for large scale stormwater treatment areas. There is a city park located in a predominately residential area with little or no current stormwater quality treatment facilities. The park consists primarily of two baseball/softball fields and is bounded by Monroe Avenue, Magnolia Avenue, Harrison Avenue, and Orange Avenue. This project involves installation of an underground exfiltration system beneath the ball fields. There is sufficient space available in the park site to allow the first half inch of runoff from the 96 Acres (+/-) east of the park to be diverted to the exfiltration system, preventing contaminants in the initial runoff from a storm from being discharged to the Banana River. The project area is shown in Figure 7-6. Both options for this project will involve the installation of a diversion structure at Madison Avenue and Magnolia Avenue with conveyance piping to the exfiltration systems. The exfiltration systems would be installed underground, with the ball fields being restored to existing conditions on the surface. Option 1 would utilize precast concrete vault structures with open bottoms for stormwater storage and exfiltration. Option 2 would utilize perforated pipe set within rock trenches for stormwater storage and exfiltration.

Please refer to the attached MiniPanel cutsheet. The reason why we had requested the SOR was that EDI would also like to offer an expansion of their design recommendations for your consideration. There has obviously been a calculation performed to arrive at an airflow of 3350 scfm. We have no idea what SOTE might have been used to arrive at that number. Advanced technology membrane aeration systems offer SAE in the range of 5-12 lb O2/hp-hr compared to surface aerators at 2.5 lb O2/hp hr. Fine bubble offers a wide range. EDI would like to offer to present a low, a medium and high efficiency design so you may evaluate the merits of each and recommend a design that presents the best long term cost of ownership. If you could provide us with the SOR (lb oxygen at standard conditions) as previously requested, EDI can run these designs very quickly. Please let me know if you have any questions or need additional information. Thanks. Sam   Sam Gutridge President EnviroSales of Florida, Inc.

Duplex Dry Weight = 32 lbsDuplex Operational Weight = 2.8 lbs EDI FLEXAIR® MiniPanel™ diffuser is a unique fine pore, flexible membrane diffuser that provides superior operational flexibility and oxygen transfer efficiency compared to other membrane or rigid fine pore (ceramic) diffusers. The MiniPanel diffuser features an exclusive top-half only perforation design. This design produces opti-mum oxygen transfer efficiency performance. A full 366 in2 (0.236 m2) of perforated area is provided with a single MiniPanel diffuser (732 in2 [0.472 m2] per dif-fuser assembly). The geometry of the diffuser sup-port high diffuser density applications over 65% floor coverage when the highest oxygen transfer efficiency is desired. Unique to the FLEXAIR product is the ability to con-figure the diffuser for the objectives of the application. The MiniPanel diffuser may be configured with a stan-dard, micro pore, or nano pore membrane for opti-mized OTE and operating pressure performance. All FLEXAIR diffusers are configured with premium qual-ity membranes that are engineered by the Membrane Technologies division at EDI. Alternate membrane materials and perforation patterns are available for non-standard industrial or municipal applications. An integral triple check valve feature prevents the backflow of liquid into the diffuser and piping. The FLEXAIR MiniPanel diffuser is ideally suited for on/off applications and requires minimal maintenance for long-term performance. A. Active Perforated Area= 732 in2 (0.472m2)B.

They have come up with the following: Attached is a revised design/performance summary, based on an AOR of 7,500 lb/day to both tanks. For reference, I’ve included the estimated air rates in the performance summary. Our calc’s show more air being required for the AOR condition as previously estimated by the Engineer. The overall diffuser count is now lower. With a lower overall demand, I also reduced the aerated area from 150’ in each pass to 125’ in each pass. We designed for roughly 2.0 SCFM/Diffuser at the Max. Mo. condition, allowing for turn-down with all grids operating. Keep in mind that from a turn-down standpoint, with multiple grids per pass, they will also be able to shut off grids if need be. Budget price for the revised design, (8) grids with a total of (2,160) 9” membrane disc diffusers, is $95,000. Hope this gets you what you need. Let us know if we can be of any further assistance.

Our design is very rough and preliminary. We have not computed a range, so please use the single point only. Because we are designing based on the max month, we will not require much turnup, if any. Turndown will be required. There will be one dedicated blower for each basin with about 1675 SCFM for each blower. We expect about 50% turndown on the blowers (about 840 SCFM). If you have any other questions, please let me know. Thank you, Jared A. Francis, E.I.

Do you need more demands modeled? The range of flow has a lot to do with layout and diffuser selection, so a minimum and maximum demand would help. Please let me know if you have this, or of the single point needs to be used only. If so, will turnup, turndown, or both be required? I just got Sanitaire’s reply based on 7500 cfm.

In addition, the memorandum analyzes the gravity sewer and lift station capacities to develop preliminary alternatives that will increase reliability of the collection system. 1.1 Background The general alignment of the gravity sewers, including Lift Station (LS) No. 9 and LS No. 2’s northern and southern tributary (service) areas are depicted in Figure 1. LS No. 9 tributary area is the southernmost tributary area in the City’s collection system and generally consists of multifamily condominiums. LS No. 9 is a duplex submersible type station and is located adjacent to Banana River Road. Wastewater from LS No. 9 is discharged, via a force main, to a manhole along Holman Road. The sanitary waste is then conveyed by gravity along Holman Road and through several private developments, including the Cape Shores Condominiums and the Cocoa Palms Mobile Home Park and ultimately discharges into LS No.2 on Center Street. Wastewater flow from LS No. 2 is pumped into the LS No. 1 gravity tributary area prior to repumping to the WWTP. This scope and evaluation focuses solely on LS No. 2’s southern tributary area. No issues were reported in the northern tributary area of LS No. 2. Upon meeting with the City, the operations staff revealed that the primary problem with gravity sewer system occurs at a manhole adjacent the 399 Holman Road residence, the manhole that LS No. 9 discharges wastewater flow into. The residence at 399 Holman Road was constructed on a depressed plot where the home’s finished floor elevation is 1.05 feet below the top of the manhole. When both pumps at LS No. 9 are operating continuously for a few minutes, the downstream manhole surcharges as a result of insufficient conveyance capacity in the gravity system. When the flow stages up in this manhole, the MEMORANDUM To: Mr. Jeff Ratliff Public Works Director City of Cape Canaveral From: Mr. Brian Foulkes, P.E. Mr. Stephen Glatthorn, P.E. Tetra Tech Subject: Lift Station No. 2 Gravity Sewer Evaluation Tt #: 200-52528-12002 Date: June 15, 2012 Mr. Jeff Ratliff Cape Canaveral Utilities June 15, 2012 Page 2 residence at 399 Holman Road is at risk of sewage backing up into the gravity service line, and potentially into the home under worst case conditions. The City has rerouted the gravity service connection from the 399 Holman Road residence downstream of the LS No. 9 discharge manhole; however, the City is still concerned that backflow could occur under peak flow conditions. The City has mitigated backup potential in the gravity system by temporarily modifying LS No. 9, to only allow one (1) pump to operate at any time. The City’s primary goal is to develop a cost effective solution to eliminate backup conditions at the Holman Road property. The City also has concerns about the hydraulic capacity of the gravity sewers in the LS No. 2 gravity sewer tributary area. Additional information was provided by the City or obtained from other sources for this review as follows: 1) General map of the City’s sanitary sewer system (Figure 1) 2) LS No. 9 pump run times for the most current 12 month period. 3) Pump curves for LS No. 9 4) As-built drawings for LS No. 9 & LS No. 2 5) City of Cocoa water billing records for customers in the LS No.9 tributary areas under investigation for the most current 12 month period 6) Brevard County Property Appraiser land use information 7) Survey of 399 Holman Road property and MH 1, 2 and 3 For reference, the approximate hydraulic capacity of various size sewer lines based on minimum required slopes are presented in Table 1. The hydraulic capacities are for reference only. A survey including slope analysis of the entire tributary was not part of this assignment. It is assumed that the gravity sewers were constructed to minimum standards; however hydraulic capacities may vary based on actual slopes. TABLE 1 NOMINAL HYDRAULIC CAPACITY OF VARIOUS SEWER PIPES AT MINIMUM SLOPE (PER 10 STATE STANDARDS) Sewer Diameter Minimum Slope Hydraulic Capacity(1) 6-inch 0.6% 195 gpm 8-inch 0.4% 343 gpm 10-inch 0.28% 520 gpm 12-inch 0.22% 750 gpm (1)Assumes roughness factor of .013 (rough PVC) using Manning Equation. Mr. Jeff Ratliff Cape Canaveral Utilities June 15, 2012 Page 3 2.0 EXISTING SYSTEM REVIEW A review of the existing LS No. 9 and No. 2 tributary areas and capacities was conducted through the use of available “record” information as well as field inspections by Tetra Tech engineers. This section reviews the finding of the field inspections and lift station drawdown tests performed. In addition, the analysis reviews pump runtime data and number of residences in the tributary areas to estimate both the existing and required hydraulic capacity of the gravity system. Alternatives will be developed from these estimates. 2.1 Field Inspections Tetra Tech performed initial field inspections of the manholes, sewer inverts and diameters between LS No. 9 and LS No. 2 on March 19th and April 23rd, 2012. The field data collected, including the invert depth, diameters and overall manhole depths along the gravity sewer route, is summarized in Figure 2. Additionally, Figure No. 2 includes manhole (MH) numbers that will be referenced throughout this evaluation. The uneven interior diameters of the gravity sewers are attributed to previous slip lining improvements. During field visits, it was visually observed that when LS No. 9 was operating (with only one pump), the manhole adjacent to the 399 Holman Road residence (MH No. 1) and the downstream manhole (MH No. 2) staged up approximately 12 inches above the invert. Also, the gravity sewer diameter exiting MH No. 1 was measured to be approximately 7.5 inches, while the gravity sewer diameter entering MH No. 2 was measured to be approximately 6 inches. The exact cause of the neckdown in the gravity main is unknown but it is suspected to be the reason for the wastewater staging up in the manholes. MH No. 1 and MH No. 2 were surveyed to determine the slope of the gravity sewer, which was found to be approximately 0.4%. A slope of 0.4% is an acceptable minimum slope for an 8-inch pipeline, but does not meet the required slope of a 6-inch gravity sewer. 2.2 Lift Station No. 9 Drawdown and Runtimes The existing pumps at LS No. 9 are each rated for approximately 350 gpm, which was confirmed via on- site drawdown pump testing. At peak flows when both the lead and lag pumps are operating, the pumps are estimated to operate at approximately 420 gpm, which is in excess of the hydraulic capacity of a 6- inch or 8-inch gravity sewer at minimum slopes. The existing pump curves and the estimated system curve illustrating the pumping conditions described above are displayed in Figure 3. Tetra Tech also reviewed the pump run times over the last 12 months collected from LS No. 9. Table 2 summarizes some of the selected maximum runtimes for this time period. The values indicate that the peak daily flows are up to 88,200 gpd. In general, the average number of starts appears to be Mr. Jeff Ratliff Cape Canaveral Utilities June 15, 2012 Page 4 approximately 40-60 per day and the average daily runtimes appear to be between 80 and 120 minutes per day, which is estimated to be a flow range of approximately 28,000 to 42,000 gpd. The number of starts and runtimes per day appear to be low in comparison to typical engineering standards, which indicates that the pumps are oversized. As mentioned previously the City personnel have modified the controls at LS No. 9 to only allow one pump to operate, the LS has been operating successfully in this arrangement for many months with no issues.

The LS No. 9 tributary area appears to be built out, thus no additional wastewater flows is expected in the future. Mr. Jeff Ratliff Cape Canaveral Utilities June 15, 2012 Page 5 Projected wastewater flows were based on Florida Administrative Code (FAC) Chapter 64E wastewater generation rates and are summarized in Table 3. Tetra Tech also estimated potable water usage within the lift station tributary areas, as wastewater generation is typically between 70-80% of potable water usage. However the Chapter 64E generation estimates resulted in more conservative requirements and will be used for the evaluation. TABLE 3 WASTEWATER GENERATION BASED ON PROPERTY TYPE Property Type Average Wastewater Generation (gpd/unit) Single Family Residence 250 Multifamily (MF) - (1 beds) 100 MF or Hotel Room (HR) - (2 beds) 200 MF - (3 beds) 300 Commercial/Industrial 750 Table 4 illustrates the number of units and projected wastewater flows for each condominium in the LS No. 9 tributary area. The table, which calculates a conservative estimate of wastewater flows, indicates that the existing pumps could be replaced with smaller capacity pumps (approximately 203 gpm) while providing a level of service consistent with engineering standards. Reducing the capacity of the pumps would help reduce the amount of flow staging that occurs in the discharge manhole and other manholes in the LS No.2 southern tributary area, however staging would still occur where sections with diameters are smaller than 8–inches.

The flow generation calculations take into account the design discharge of LS No. 9 into the gravity sewer. The southern tributary area of LS No.2 was divided into five (5) zones as denoted in Figure 4. Wastewater from each zone can be cumulatively added to determine the estimate flow and gravity sewer requirements at the approximate termination of each zone. Table 5 displays the projected wastewater flows for the existing LS No. 2 tributary area per zone. Table 6 compiles the cumulative flows per zone based on the existing conditions and compares these flows to the both the required and existing gravity sewer diameters in each zone. The table indicates the capacity of gravity sewer system measured during Tetra Tech’s inspections are undersized due to the LS No. 9 discharging into zone 1. If pumping capacities at LS No. 9 remain unchanged, the LS No.2 southern tributary gravity sewers should be increased to a minimum of 10-inches in diameter at minimum slopes to avoid staging in the manholes. 2.5 Capacity Analysis Based on Build Out The southern tributary area for LS No. 2 is essentially at build out except for a large track in zone 2 at 6335 N Atlantic Ave. currently occupied by a miniature golf course and restaurant. Discussions with the City’s staff have indicated that the construction of a hotel or condominium complex could potentially be constructed at the property. A search of the property indicated it was on the market in 2010, but has since been taken off. The lot contains approximately 5.7 acres and can accommodate up to 171 hotel rooms, according to the 2010 real estate listing. If this lot was developed into a hotel or resort, the gravity system would connect to the existing gravity main between Holman Road and Cape Shores Drive. The existing gravity sewer is currently undersized in this area and cannot accommodate additional flow. The capacity improvement recommendations in Section 4.0 include provisions for the potential development of this parcel into a hotel or resort.

Mr. Jeff Ratliff Cape Canaveral Utilities June 15, 2012 Page 8 3.0 ALTERNATIVES TO ELIMINATE BACKUPS This section will summarize the analyses recommended to prevent staging and eliminate backups into the Holman Road property. The results of the investigation appear to establish three (3) potential alternatives for preventing backflow to the Holman Road residence: 1. Possible relocation of force main discharge to west side of North Atlantic Avenue (A1A) to bypass LS No. 2 tributary area and pump directly to LS No. 1 tributary area. 2. Install a private lift station at or nearby the 399 Holman Road residence to prevent sewage backflow. 3. Install a gravity service line from 399 Holman Road to LS No. 9, sized for future conditions if the nearby vacant property at 6101 N. Atlantic Ave. is commercially developed. 3.1 Alternative 1: Force Main Relocation Construction of a force main to discharge wastewater from LS No. 9 to LS No. 1’s tributary system and bypass of LS No. 2 tributary area requires approximately 3,600 linear feet of force main along with significant improvements to the gravity sewers in the LS No. 1 tributary area. Over 2,500 linear feet of force main would need to be constructed in the congested right-of-way of A1A. This alternative does not eliminate the potential for a backup; a blockage in a downstream gravity sewer could result in staging of the upstream manholes and a backup at the residence. Analysis revealed this alternative is not feasible due to the overall cost, constructability issues and incomplete elimination of backups. 3.2 Alternative 2: Private Lift Station Installation of a private lift station that would solely serve the 399 Holman residences would eliminate the risk of backup currently experienced. The lift station construction would likely be a small duplex grinder station similar to those already installed for residences along the Intercoastal waterway. It is likely that the lift station could be installed near the property along the south or west side of Holman Road and discharge into the same manhole adjacent to the residence (MH No. 1). An easement may be required for this option and the City may be compelled to maintain the LS to appease the resident’s concerns. Installing a pump station for the 399 Holman Road residence eliminates the potential sewage backup at the residence, but will not reduce the staging in the manholes. Figure 5 presents a preliminary depiction of this option. Mr. Jeff Ratliff Cape Canaveral Utilities June 15, 2012 Page 9 A preliminary cost estimate of $37,485.00 has been estimated for Alternative No. 2. A line item breakdown of the cost estimate is located in Table 7. These costs are budgetary in nature and would require additional development during preliminary design. For all alternatives, the cost of acquiring easements has not been included in the estimate, but could be required.

This alternative involves the construction of approximately 750 feet of gravity sewer to route flow back to LS No. 9. Although there is a slightly closer manhole just south of the pool at the Hidden Harbor Condominiums, the manhole appears to be too shallow to direct the sanitary flow at minimum slopes. Based on property appraiser’s maps, it appears that there is right-of-way along Banana River Road to construct the gravity sewer. A private residence at 6101 N. Atlantic Ave. would need to be crossed, which would require the acquisition of an easement if the existing easement is not wide enough to construct the new gravity sewer line. Preliminary calculations indicate that a 4-inch gravity pipeline installed at a slope of 1.0% to maintain a minimum velocity in the pipeline would provide sufficient capacity for the 399 Holman Road residence. However, the City’s operational staff indicated that Mr. Jeff Ratliff Cape Canaveral Utilities June 15, 2012 Page 10 installing an 8-inch line would be beneficial if any future development occurs at 6101 N. Atlantic Avenue property, which is currently vacant and is partially zoned for commercial use. Rerouting the gravity service from 399 Holman Road to LS No. 9 eliminates the potential sewage backup at the residence, but will not reduce the staging in the manholes, resulting from the limited hydraulic capacity of the existing gravity sewers. Figure 6 presents a preliminary depiction of Alternative 3. A preliminary cost of $92,978.00 has been estimated for Alternative No. 3. A line item breakdown of the cost estimate is located in Table 8. These costs are budgetary in nature and would require additional development during preliminary design.

Backup elimination Alternative No. 3 features a moderate cost, is constructible with minimal impacts to the surrounding community, allows for future connections along Holman Road and provides a negligible maintenance increase for the City and is the preferred alternative. However, implementation of Alternative No. 3 alone will not address the root cause of insufficient capacity of the gravity sewers in the LS No. 2 southern tributary area. Without increasing the capacity of the system, staging problems will continue and could result in sanitary sewer overflows in other areas of Mr. Jeff Ratliff Cape Canaveral Utilities June 15, 2012 Page 11 the system. The following sections will investigate the deficiencies in the LS No. 2 southern tributary area and provide recommendations to increase reliability of the system. 4.0 CAPACITY IMPROVEMENTS FOR LS NO. 2 SOUTH TRIBUTARY AREA As indicated in Section 2.0, the LS No. 2 southern tributary system is currently undersized based on current estimates. It is recommended that improvements to increase the hydraulic capacity be implemented. The section investigates reduction of pumping capacity at LS No. 9 and increases in gravity sewer size to increase the hydraulic capacity in the tributary area, along with budgetary costs and a review of construction methods. 4.1 Reduced Pumping Capacity at LS No. 9 The provided runtime and pump start data, in conjunction with the build out wastewater generation calculations in the LS No. 9 tributary area, indicate a reduction in pump capacity at LS No. 9 is possible. The reduction results in a smaller diameter requirement of the gravity sewers throughout the tributary area. Table 9 indicates that zones 1, 2, and 3 require gravity sewer diameter of 8-inch, while zones 4 and 5 require 10-inch diameter, based on existing generation rates and reduced pumping capacities at LS No. 9. However, these capacity improvements do not account for the potential future development at 6335 N Atlantic Ave located in zone 2. Improvements to gravity sewers would be required in zones 2, 3, 4 and 5 if the property was developed into a hotel or resort.

Mr. Jeff Ratliff Cape Canaveral Utilities June 15, 2012 Page 12 4.2 Gravity Sewer Improvements To accommodate the proposed development, Tetra Tech analyzed the available capacity if zones 2, 3, 4 and 5 were upsized one pipe diameter from the values listed in Table 9. Based on the analysis, upsizing gravity sewers one pipe diameter results in an available future hydraulic capacity of 100 gpm (36,000 gpd), allowing accommodation of a 180 room hotel or resort. Table 10 presents the estimated peak cumulative wastewater flows per zone and required future gravity sewer requirements to accommodate the estimated build out condition. It should be noted the flow estimates are based on minimum slope requirements of the gravity sewers. If additional slopes can be achieved during the design phase, the gravity sewer diameter requirements could decrease; however, additional investigation and survey are required to accurately determine the slopes. The future development at 6335 N Atlantic Ave., includes a 5.7 acre lot that fronts to N. Atlantic Ave. As previously stated, a 2010 real estate listing the property can accommodate up to 171 hotel rooms. The future development assumption only include this 5.7 acre parcel, however, if a developer acquired the three residential properties along the intercoastal, a potential waterfront resort of greater than 10 acres could be constructed. The acquisition and rezoning requirements make this option improbable; and was not included in the analysis. Figure 7 presents a preliminary depiction of the capacity improvements. These improvements minimize gravity sewer diameters while accommodating for future development in zone 2.

Mr. Jeff Ratliff Cape Canaveral Utilities June 15, 2012 Page 13 4.3 Construction Methods Based on the preliminary inspection and capacity analysis, the gravity system could require up to 4,000 linear feet of gravity main replacement. The effort to complete this work would be substantial and may need to be addressed as part of a 5 year capital improvement plan (CIP). Completion of these capacity improvements would reduce manhole staging and provide a high level of service for all existing and future customers in the LS No. 2 southern tributary area. It is likely that a combination of conventional replacement and pipe bursting would be used for the sewer improvements. The first replacement option, conventional removal and replacement, involves bypass pumping, excavation of the existing pipelines, removal and replacement of the existing pipe, backfilling, and restoration of areas disturbed by the construction activities. The second replacement option, pipe bursting, involves using a trenchless technology that is somewhat similar to directional drilling, however, the existing pipe is used to provide a "pilot conduit" for bursting equipment. Pipe bursting technologies allow for increase of pipe size up to two diameters greater than the current gravity sewer diameter. This equipment breaks the existing pipe and pushes it into the surrounding soil to make room for the new pipe that is pulled through the larger opening. In cases where there is minimal cover over an existing pipe, the bursting process often results in "heaving" of the ground surface. Existing service laterals must be excavated and connected to the new pipe after the bursting and pulling operations are complete. Open trench methods are more cost effective in areas of open space or unpaved roadways. Pipe bursting is more cost effective in congested areas or deep gravity sewers, where restoration is more extensive. 4.4 Preliminary Costs A preliminary cost estimate for the capacity improvements described above are $927,927.00, a line item breakdown is presented in Table 11. Estimated costs for the capacity improvements are conservative and assume replacement of gravity sewers in all zones. However, actual mains to be replace should be based on a complete survey and inspection of the tributary area, as the size gravity sewer in zone 4 was not field verified and may not require replacement. A contingency has been added to the total cost pending an additional investigation to more accurately determine the magnitude of the improvements needed.

Additional contingency pending full review of system Mr. Jeff Ratliff Cape Canaveral Utilities June 15, 2012 Page 15 5.0 SUMMARY AND CONCLUSIONS Based on this evaluation, it is recommended that one of the backup elimination alternatives be selected initially to alleviate backflow problems in a timely manner, so that capacity improvements could be constructed in phases with a longer term capital improvements plan. Backup elimination alternative No. 2 and No. 3 are feasible options for preventing backup to the 399 Holman Road residence. Backup elimination Alternative No. 3 has the benefits of reduced maintenance and capacity for future connections along Holman Road; however, the Alternative will not address the root cause of insufficient capacity in the LS No. 2 southern tributary area. Without increasing the capacity of the system, staging problems could continue and result in sanitary sewer overflows in other areas of the system. Therefore, it is recommended the City implement the outlined capacity improvements to address the deficiencies in the existing gravity system and allow for future build out conditions in LS No. 2 southern tributary area. Additional investigations are required to determine the exact length and size of the gravity main improvements; however it is expected that the construction would require the installation of between 2,500 to 4,000 linear feet of gravity sewer, by conventional removal/replacement and pipe bursting techniques, depending on the location and slope of the existing gravity sewer. In summary, it is recommended that the City route flow from the Holman property directly to LS No. 9, reduce the pump size at LS No. 9, and implement the hydraulic capacity improvements in the LS No. 2 southern tributary area.
