AGENDA REPORT
CITY COUNCIL OF THE CITY OF CAPE CANAVERAL
i
SUBJECT: CONSIDERATION: NORTH CENTRAL DITCH STORMWATER IMPROVEMENT
PROJECT - PROPOSAL TO INSTALL A BAFFLE BOX SYSTEM
DEPT /DIVISION: PUBLIC WORKS /STORMWATER
1
I Requested Action:
i l
City Council review and consider a proposal to install a stormwater baffle box system instead of a wet pond
system for the North Central Ditch Stormwater Improvement Project, as recommended by the Florida I
I
Department of Environmental Protection (FDEP).
i
i
{ Summary Explanation & Background:
i
I On 06 -19 -07 the City Council approved a change in the project scope to a wet pond system as recommended
by Stottler, Stagg & Associates and our stormwater administrator, with an estimated project cost of $524,770.
i
These plans were submitted to FDEP for review and approval, and FDEP suggested that the City consider a
baffle box system with an estimated project cost of $353,000.

The attached memo from the stormwater administrator outlines the pros and cons of the two stormwater
treatment methods, and comparison of the project grant and costs.

Re: Agenda Item — October 16, 2007 Meeting
North Central Ditch Stormwater Improvements — Proposed
Changes
Work To Date:
• City has submitted design drawings to construct an online wet detention pond and associated
structures north of West Central Boulevard (see attached schematic diagram);
• Online wet detention pond to be constructed on City -owned property approximately 450 feet
north of West Central Boulevard;
• Design drawings currently under review by the Florida Department of Environmental
Protection (FDEP);
• Estimated cost — entire grant amount of $524,000+;
• Stonnwater permit could be challenging due to proposed online pond versus ofline pond —
i however, can most likely be obtained; and
• Next task — complete and submit stormwater permit application and advertise for bid.
BENEFITS:
• Provides good water quality benefits through use of a wet detention pond; and
• Eliminates open ditch north of West Central Boulevard.
DRAWBACKS:
• Maintenance issues — difficult to maintain pond area with limited staff;
• Doesn't include treatment of stonnwater from additional 42" pipe from the west; and
• Project will use entire grant amount.
FDEP Proposed Scenario:
• FDEP approached the City a few weeks ago with a proposed alternative design;
• FDEP is "pushing" the installation of mega bale boxes — cheaper stonnwater devices which
provide similar amount of water quality improvements as major construction projects (see
attached schematic diagram);
3
• Numerous mega - structures under construction in the Panhandle area — FDEP under contract
with Suntree Technologies (Cocoa, FL) to monitor baffle boxes (see attached photo from
FDEP);
• FDEP is looking for a mega -baffle box site in our area (outside of the Panhandle area) — good
publicity;
• Project would include four baffle boxes — three in Central Ditch and one on 42 "-diameter pipe
from the west; and
• Estimated cost — approximately $353,000 (see attached cost estimate) — all funds spent to date
toward City's 40% grant match (see attached table).
1 BENEFITS:
• Relatively easy to install, easy to maintain (inmates to clean debris) and monitor, and
provides similar water quality benefits as wet pond strategy;
• Includes treatment of stormwater from additional 42" pipe from the west;
• FDEP performs all monitoring tasks (long -term research project);
• Stormwater permitting process much easier — project to be completed sooner;
• Excellent publicity for the City; and
• Overall reduction in project costs. 1
DRAWBACKS:
• Only addresses vegetation cleanup of immediate area around West Central Boulevard.
Future Work On the Central Ditch:
• Set aside specific amount of funds (e.g., $40,000) annually from stormwater fund to clean
up Central Ditch north of West Central Boulevard;
• Another FDEP /SJRWMD grant will address stormwater quality in the southern portion of
the Central Ditch; and
• Entire intersection to be "spruced up" with available grant funds and City funds.
s
Based upon the review of both strategies and costs for stormwater improvements, City staff
recommends the approval of the FDEP proposal for the installation of baffle boxes at the
intersection of the Central Ditch and West Central Boulevard versus the construction of a wet
detention pond system.

1 Jeff: Our project G0184 to implement BMPs to improve the quality of
stormwater runoff through the Central Ditch to the Banana River was funded
1 with an FY05 section 319 grant. Engineering and design costs incurred for
the project since October 1, 2004 count towards the City's match. Page 5 of
3 15 of Attachment A of the agreement provides a breakdown of the project
funding and shows a match contribution of 40% or $209,848 if the full amount
of grant funds is used. $74,912 of this match is shown to be provided by the
SJRWMD for implementing the BMPs and the remainder is provided by the City.
If there are cost over runs for the engineering these can count towards the
City's match. Please let me know if you have any other questions. Mike.

Re: Agenda Item for June 19, 2007
Additional Funds — North Central Ditch Stormwater
Improvement Project
The City Council approved funds in the amount of $53,000 for Stonier Stagg & Associates (SSA) in
June 2006 for the completion of engineering design tasks/engineering drawings for the North Central
Ditch Stormwater hnprovemme t Project The project was to include the construction of a stormwater
system as submitted to the Florida Department of Environmental Protection (FDEP) in the Section 319
grant application in 2005. However, based upon the results of surveying activities conducted by SSA, it
became apparent that the proposed design (system of culverts and dry retention areas) submitted in the
grant application would not be feasible — due in part to low elevations near residences along the
northern portion of the Central Ditch. Several attempts were made to modify the proposed design (i.e.,
'make it fit The site') — but none were deemed suitable.
Therefore, an alternative engineering design was developed as described to the City Coimcll in the
workshop on June 19, 2007. This proposed new design (system of culverts and a wet detention pond on
City-owned property) was presented to the FDEP the week of June 4 — the FDEP concurred that the
new design project was adequate to meet the Section 319 grant requirements.
SSA has requested additional funds ($9, 040.00) to complete the engineering design tasks /engineering
drawings for the alternative engineering design — these tasks include additional surveying, drafting, and
engineering design tasks (cost breakdown attached). The original grant application included $59,848.00
in funds for the completion of engineering design tasks/engineering drawings — the proposed funding
amount is $62,040.00. Original funds ($59,848.00) are included in the FY2006-2007 budget under the
Canaveral Ditch Project (6310) - Stormwater Fund. The total budget far project completion ('including
grants) is $524,618.00.
Recommend the approval of additional funds in the amount of $9,040 to SSA for completion of
additional engineering design tasks/engineering drawings for the North Central Ditch
Stormwater Improvement Project.
