match. Okaloosa County staff is in the process of requesting approval from the Board of County Commissioners to enter into a funding agreement with the Northwest Florida Water Management District to fund the survey and computer model. They have outlined a preliminary scope of work with the assistance of one of their consulting engineers (please see backup). Given the time constraints for this program, staff believes it is necessary to formalize the Otis commitment to this multi-jurisdictional effort to avoid any further delays. Recommendation: Staff requests Council approval to partner with Okaloosa County for a Northwest Florida Water Management District grant to study the Gap Creek Drainage Basin at an amount not to exceed 17,600. 00, or approximately 30% of the grant match. These funds will be used to accomplish the first steps of a drainage basin improvement project for the Gap Creek Watershed area. If approved, sufficient funding is available in account 001- 8019- 541- 6997 ( QP 5019 - Stonn Drainage Program). Submitted By: df{Jto Samuel O. WIlson IV, Environmental Specialist yl/--- D?

Public Works Director SUBJECT: Request approval to enter into aD agreement with the Northwat Florida Water Management Distdet to rud . Study . fthe Gap Creek.Dl'alDage Basin DISTRICT: FOUR REQUESTING D~~ U- Public Wotks - TMm:D:: aT~ N1 OF ISSUEI The Gap Creek Dminage Basin is a 2.9 square mile area which comprises both uninco1porated.county and portions ofthe City of Fort Walton Beach, The basin is curreut1y at capacity and can no longer acoom.modatc additional stormwater runoff and the water quality of the run ofttequires enhancement so as not to negatively impact Cinco Bayou. IA~ GROtJND & ANALYSIS: The County, Fort Walton Beach, Choctawhatchee Basin Alliance. the Front Porch Community Association.the Florida Department ofEnvironme a.1 Protection and 1he North West Florida Water Management District ( NWFWMD) have aU expressed a desire to confton.t these problems. A site meeting was held in January of this year to evaluate the area and discuss possible solutions to flooding and water quality issues. Because of the constraints associated with the stormwater capacity issues it became apparent that a study of tho watershed area would be requjred SO that the impact ofproposed solutions could be completely understood. The group did not want to solve one problem and inadvertently create another. Smffapproached the NWFWMD to discuss possible fimd;ns alternatives. The District does not currently have a grant program that funds studies;however. they have reviewed our request and dctcnnined that the project is important enough f:or them to enter into an agreement with the County. 'Ibis agreement would teq\1b:a 50% e match from the County and tho study performed would be requimd to address water quality issues..A draft Scope of Work (at1ached)has beon developed and provided to the District for their review. The District has provided a draft agreement will be provided to the County for review, processing and accoptance. The District staffwill then present the agreement to their BoanI at their June meeting. The match equiremeqt is $ 58,357. 00.

Engineering to submit a scope ofwork to assist tho County in a study ofthe Gap Creek W~ w~ ow~~~~~~~~~ W~~~~~ q~~ m the watershed area. Gap Creek outlets into Ciuco Bayou,which bas Total Nitrogen and Total Phosphorus Annual Pollutant Loading levels that exceed 98% of tho streams in 1be county end Biochemical Oxygen Demand and Total Suspended Solids Annual J}ol utant Loads that exceed 97 % ofthe streams in the county based on the Okaloosa County Stormwater Master Plan. Cinoo Bayou is a heavily used area for water based recreation and it outlets into western Choctawhatchee Bay. The Gap Creek watershed is located in the coastal area of the County and is comprised of approximately 2.9 square miles. The watershed is bounded on the north by Cmnel RDad; on the south by Lovejoy Road and Hollywood Boulevard; on tho west by a runway on Hurlburt field and on the east by Beale Parkway. SCOPE OF WORK Having made a visual fnspcction of the watershed area on Apri127, 2007, preHminR'}' HDR proposes a multi- task scope ofwork. Tuk 1. KicbflMeetIq HDR and Okaloosa County win meet to introduce the HDR.team and the County prime contact;review the W01'k tasks; estabHsh a realistio project schodulo and address any issues or concems that nood to be discussed prior to begfnnfng the project. Delivemble: Prepared Meeting Minutes Projeot Schedule that meets County Approval Tuk 2. Data COIlecdoD aDd Reriew HDR will coUect ftom.tho County, and other sources as appropriato.availablo intormation and da1a relatod to land use activity in the watershed and adjacent aroas, including stonnwater designs tOr developments in the watershed. Data will be co11octed 17' d SEV9 ' oN Wd 6l : 1 L 00 l ' 6 ' ~ ' eVoj on water quality studies, monitoring activities or projects that have included the watershed in their scopes. Information on water and sewer lines, pump stations,septic system.s that are in the study mea will also be assembled for use in the analysis. The county will famish the relevant layers trom their GIS data base for use on the study- Task 3. Field investigation I Model Recommendation While Task:2 is underwaYt HDR.will initiate a detailed field investigation. The HDR team members wU1 visit and traverse the watershed on foot during both wet and dry conditions. They will take digltal photographs and compile a visual record of conditions as they actually exist. Based on the existing conditions.a water quality model will be proposed. HDR wi11 evaluate several USBPA approved computer models P ( 8-UCM. S~ SWMM, WASP6, BASINS, QUAL:2B). Tho exact models to be used will be determined by conditions in the watershed. HDR will recommend a model for approved by the County. Tho model will provide the scientific basis for selecting water quality improvement options. Deliverable: A report on the existing site conditioDS with the water quality parameters itemized that we would recommend evaluating and a recommendation of tho water quality model to be used to analyze the watershed. Selection of the water quality model to be used for the evaluation wJ1l dlcta1:e the survey needs. Task 4 Survey Subsequent to the tie1d investigation,HDR will contract for a survey of the wateJ:shcd. area. This survey will bo used to provide the data needed to be ablo to formulate the selected water quality model ofthe basin. The survey Scope ofWotk and fee witt be approved by the County prior to initiating work. Anticipated . survey needs include stream and ditch clwmel sections at selected locations and as- built dotails of existing stormwater facilities. An allowance ofS20,OOO. OO has been set up in the fee schedule fOrtbe survey. DeJive.rable: Survey TBlk 5 ExlstIDg CoDditioa. AuIytiI Existing HECl and HBC-RAS models that were developed as part of the Obloosa County Stormwater Master Plan win be evaluated to see if changes in the watershed require updating the models for tho water quantity analysis. eW J S( t9 ' oN
