Subject: Downtown Redevelopment Drainage Improvements with Pegasus Engineering.
Commissioner Wilsen, District 2 and Commissioner Firstner, District 3.
Background Summary:
A key component of the City Commission approved Downtown Master Plan is the development of the
master regional stormwater facility. Continuing engineering services firm, Pegasus Engineering, was
assigned the first step in the design process by conducting a feasibility study for the facility which was
completed December of 2017. Using the results of the feasibility study to establish the parameters for
the design of the regional stormwater facility, the City successfully solicited Engineering services for the
final design and construction. GAI Consultants were awarded the design of the Downtown Master
Regional Stormwater Facility and are in the preliminary concept and design phase.
While GAI continues to develop their final product, the City is in need of immediate engineering services
to ensure the current Bluford Avenue, Oakland Avenue and City Hall Complex project improvements will
function with the future master stormwater system. Public Works is requesting continuing engineering
services firm, Pegasus Engineering, to handle these immediate tasks as their team has the most
historical knowledge from completing the feasibility study and has already been coordinating with the
various project design teams. The major portion of this proposed work will allow the City to pipe the
open drainage ditch next to existing City Hall from the railroad tracks at Franklin Street to Starke Lake,
increasing the area of developable property by reducing compensating pond storage area. Having
Pegasus complete this work allows the City's other project consultants to continue to work unimpeded
on their projects and eliminates future additional design fees on said projects. The $47,500.00 for the
work is available in the Stormwater Capital Improvements.
Public Works recommends approval of the work with Pegasus Engineering.
Issue:
Request the City Commission to approve the miscellaneous stormwater support services for the City's

Recommendations:

Downtown Redevelopment Drainage Improvements with Pegasus Engineering, for the not to exceed
cost of $47,500.00 as funded in the Stormwater Capital Improvements. Also recommend the City
Manager be authorized to approve change orders to this contract up to the limit of his purchasing
authority for each change order, and up to the budgeted amount for this project for all change orders.

(Oelrich Construction), with the design of the following drainage improvements between

to eliminate the compensating storage area planned between Taylor Street and
Kissimmee Avenue/ Railroad;
• Culvert system crossing Bluford Avenue (currently under construction by Oelrich);
• Box culvert system between Bluford Avenue and Lakeshore Drive;
• Box culvert system crossing Lakeshore Drive;

With that said, it is our understanding that Pegasus Engineering shall perform the following
miscellaneous stormwater support services for the City of Ocoee and their Consultants:
1. Prepare for and attend four (4) Project Team Meetings with City staff and representatives of
CPH, GAI Consultants, and S&ME.
2. Prepare for and attend four (4) Bluford Avenue Construction Progress Meetings with City
staff and representatives of Oelrich and CPH.
3. Perform preliminary hydraulic calculations to evaluate various culvert configurations
crossing Bluford Avenue, including round concrete pipes, elliptical concrete pipes, and box
culverts.
4. Perform preliminary modeling in order to design conveyance improvements between
Kissimmee Avenue and Lakeshore Drive to eliminate the compensating storage area.
5. Review and comment on design alternatives and conceptual shop drawings for the Bluford
Avenue culvert system, as well as the conflicts associated with the intersection of Bluford
Avenue and Oakwood Avenue.
6. Coordinate with the St. Johns River Water Management District (SJRWMD) to schedule,
prepare for, and attend a pre-application meeting to discuss the concept of eliminating
compensating storage area and increasing conveyance without adversely impacting Starke
Lake.
7. Update the existing conditions and the proposed conditions models and drainage exhibits
for the Downtown Stormwater Master Plan — Phase 1 Feasibility Study (dated December
2017) to reflect recent construction projects (Sunbelt Rental and the expansion of the
Ocoee Business Park).
8. Update the proposed conditions stormwater model to also reflect the proposed Downtown
Redevelopment drainage improvements associated with the City Hall Campus by S&ME,
(Study Area 1), the Study Area 2 Regional Stormwater Pond by GAI Consultants, and the
Bluford Avenue improvements by CPH.

9. Assist the Project Team,as needed,with the SIRWMD permit applications.
10.Assist the Project Team, as needed,with meetings and presentations to City staff and/or the
City Commission.
Once the proposed improvements are constructed, it is our recommendation that a FEMA
Letter of Map Revision (LOMR) be prepared to reflect the as-built conditions. A separate
proposal will be submitted to the City in the future to prepare a LOMR and revise the floodplain
limits based on the as-built conditions.
The above described will be performed for an hourly not-to-exceed fee amount of$47,500.00
in accordance with attached manhour and fee estimate (refer to Attachment"A").
We appreciate the opportunity to continue serving the City of Ocoee on this important
assignment. If you have any questions, please contact me directly at 407-992-9160, extension
309,or by email at david@pegasusengineering.net.
Respectfully,
