Krug 6002 Reviewed By: Department Director: City Manager: ~( . .~ Subject: Pioneer Key Regional Stormwater Pond Post Design Services and Performance Efficiency Evaluation with PEe I Professional Engineering Consultants, Inc. Background Summary: In the last fiscal year, the City completed the construction of the Pioneer Key Regional Stormwater project as a regional wet detention pond to provide retrofit water quality treatment and flood attenuation. This facility will provide treatment for the Pioneer Key mobile home communities as well as other developed and undeveloped areas along the Northwest Ditch 123-acre drainage basin in the City prior to discharge into Lake Apopka. The Department of Environmental Protection grant that funded the project construction also includes a monitoring phase to determine the effectiveness of the facility in reducing pollutant loadings that ultimately discharge into Lake Apopka. The scope of this phase requires the installation of hydrologic and water quality monitoring equipment that will collect data along with water sampling over a 6 month period. At the end of the monitoring period, a complete hydrologic and pollutant budget will be developed for the facility, and the overall performance efficiency of the system will be calculated for the evaluated parameters described in the attached scope of services. Issue: Request the City Commission direct staff to proceed with the monitoring phase of the Pioneer Key Regional Stormwater Facility Performance Efficiency Evaluation. Recommendations Recommend awarding the Pioneer Key Regional Stormwater Facility Performance Efficiency Evaluation to PEC for a not to exceed amount of $99,957.02. Attachments: PEC Scope of Services. Financial Impact: This project is adequately funded in Stormwater and through grants.

Revised January 26, 2009 Proiect Backeround The Pioneer Key regional stormwater project was constructed as a regional wet detention pond to provide retrofit water quality treatment and flood attenuation. This facility will provide treatment for the Pioneer Key I and Pioneer Key II mobile home communities as well as other developed and undeveloped areas along the Northwest Ditch (I23-acre drainage basin) in the City of Ocoee prior to discharge into Lake Apopka. Design criteria for the stormwater facility are summarized below (PEC, 2007): PARAMETER INFORMATION Treatment System Tvoe Wet detention pond Pond Area 3.07 acres at NWL Drainage Basin Area 123.44 acres Drainage Basin Land Use Mobile home parks, commercial, highways Basin Impervious Area -- Treatment Volume 0.47-inch over basin area Permanent Pool Volume 24.14 Pond Depth a.

(ERD) for Professional Engineering Consultants (PEC) and the City ofOcoee (City) to conduct a performance efficiency evaluation of the Pioneer Key Regional Stormwater Facility. This facility has been recently constructed by the City to reduce pollutant loadings discharging through the Northwest Ditch into Lake Apopka. Hydrologic and water quality monitoring equipment will be installed at this site by ERD, and field monitoring will be conducted over a period of 6 months to evaluate system efficiencies. Collection of field data and water quality samples will be conducted on a weekly basis. At the end of the 6-month monitoring program, a complete hydrologic and pollutant budget will be developed for the facility, and the overall performance efficiency of the system will be calculated for the evaluated parameters. Draft and Final Reports will be prepared and submitted to the City. PEC\PIONEER KEY REGIONAL STORMWATER FACILITY. NOV08-PAGE I Scooe of Services ERD proposes to perform the specific work efforts outlined below to conduct the performance efficiency evaluation for the Pioneer Key Regional Storm water Facility. Details of specific work efforts proposed for this project are summarized below. I. Proiect Kick-off MeetimuSite Visit: The ERD Project Director will perform a project kick-off meeting with representatives of PEC and the City to discuss details of the proposed work efforts to be performed; project schedule; contact personnel for ERD, PEe, and the City; contract management details; and issues related to site access and security. A site visit will be conducted to discuss proposed field activities and identify specific monitoring locations. It is the responsibility of the City to obtain any necessary permits or authorizations for use of the site for the proposed monitoring activities. 2. Preoare/Submit Proiect OA Plan: Development of a detailed Project QA Plan is a requirement for all projects receiving Section 319 funding. This plan provides a description of the proposed field and laboratory activities and outlines specific Quality Assurance procedures for all anticipated field and laboratory activities. This plan will be prepared by ERD prior to initiation of the field monitoring activities and submitted to FDEP for review and approval. 3. SelectlInstalllCalibrate Field Monitorin!!: EQuioment: ERD will evaluate the proposed monitoring site and appropriate field monitoring equipment will be selected to perform the performance efficiency evaluation. It is anticipated that flow monitoring and sample collection activities will occur at four separate sites at the Pioneer Key facility as follows. Locations of the monitoring sites are indicated on the attached figure. a. Site I: inflow channel from the Northwest Ditch into the pond b. Site 2: the 42-inch RCP entering the southeast comer of the pond c. Site 3: located in the lO-inch HOPE for the pond bleed-down system d. Site 4: located in the Northwest Ditch downstream from the pond Sensitive digital water level recorders will also be installed within the pond to assist in development of a hydrologic budget and to allow quantification of the magnitude of discharges through the Northwest Canal which bypass the pond system. A digital rainfall gauge will also be installed at the site along with a pan evaporation station. The autosamplers and flow monitoring equipment will be housed inside aluminum equipment shelters for security. After installation, each of the components will be calibrated according to manufacturer's instructions prior to initiation of the monitoring program. PEC\PIONEER KEY REGIONAL STORMWATER FACILITY. NOVOS-PAGE 2 4. Perform Routine Monitorin!!: ERD field personnel will visit the site once each week to retrieve stored hydrologic data and collect composite inflow and outflow samples. The operation of all on-site equipment will be evaluated during each visit. Activities performed at the site will be recorded on field notes. The monitoring program will last for a period of 6 months, with a minimum of 26 weekly monitoring visits conducted during this study. Continuous flow-weighted composite samples will be collected at each of the four monitoring locations. Each of the composite inflow, outflow, and runoff samples will be returned to the ERD Laboratory and analyzed for the following parameters: a. pH g. Total Nitrogen b. Alkalinity h. SRP c. Conductivity 1. Particulate Phosphorus d. NH3 J. Total Phosphorus e. NOx k. Turbidity f. Particulate Nitrogen 1. TSS m. Color For budget purposes, it is assumed that an average of 6 samples per month will be collected at each of the four sites, for a total of 144 stormwater/baseflow samples collected during this project (6 samples/month/site x 6 months x 4 sites). In addition, a bulk precipitation collector will be installed adjacent to the pond, and wet! dry fallout bulk precipitation will be collected on a continuous basis. For budget purposes, it is assumed that approximately 3 composite bulk precipitation samples will be collected each month, for a total of 18 samples during this project (3 samples/month x 6 months). 5. RoutinelFinal Data Comoilation: All data retrieved during the weekly site visits will be compiled into a common database on a continuing basis. The weekly field data will be reviewed and evaluated with respect to accuracy and precision of the data. At the end of the monitoring program, all of the compiled data will be summarized in both tabular and graphic formats for use in the Final Report. 6. Preoare Draft Final Reoort: A Draft Final Report will be prepared by ERD which summarizes all field and laboratory activities and provides an analysis of the performance efficiency of the system. Two copies of the Draft Final Report will be provided to the City for review and comments. 7. Attend Review Meetin!! with City: The ERD Project Director will attend a review meeting with the City to discuss comments on the Draft Final Report. 8. Preoare Final Reoort: A Final Report will be prepared for this project which incorporates the review comments provided by the City. Two hard copies and one digital copy of the Final Report will be provided to the City. PEC\PIONEER KEY REGIONAL STORMWATER FACILITY.
