The CONSULTANT shall be responsible for designing a drainage and stormwater management system. Design work shall comply with the requirements of the appropriate regulatory agencies and the FDOT’s Drainage Manual. The CONSULTANT shall develop a drainage map based upon available information and field reviews. The available information should consist of old Florida Department of Transportation Plans, USGS Quadrangles, USGS Studies, NWFWMD Studies, FEMA Studies, Local Government Agency Studies or Contours, etc. The drainage map should be included in the Hydraulic Design Study. The Hydrology should be by regional or local regression equations, or by the rational method. An assumed velocity should not be used. The CONSULTANT shall document the Drainage Design in the Drainage Design Study. The Design Study should show that the design requirements of the COUNTY, FDOT and FAA have been met. The CONSULTANT has the responsibility for determining the need, appropriate locations, and sizes for water management facilities, and drainage outfalls. The CONSULTANT shall refer Phase I – NEPA Environmental Assessment for Packet Pg. 600 preliminary pond sites studied. The CONSULTANT shall be advised that pond locations must be located within the footprint of the Phase I – NEPA Environmental Assessment. The CONSULTANT shall evaluate the need for diversion ditch systems along the project length to prevent comingling of overland runoff with roadway runoff in order to minimize pond sizings. The CONSULTANT shall provide the COUNTY a Drainage Design Documentation. The documentation shall include a narrative description of existing and proposed drainage structures, conditions, and facilities, and a listing of environmental regulatory permits required. Hydrologic and hydraulic drainage computations for the design presented in the plans shall be included along with supporting design information such as drainage maps, geotechnical data (such as soil borings and permeability tests), and correspondence that directly affected design decisions. The CONSULTANT shall coordinate fully with the appropriate permitting agencies and the COUNTY’s staff. Activities and submittals should be coordinated through the COUTNY’s Project Manager. The work will include the engineering analyses for any of the following: 6.1 Determine Base Clearance Water Elevation Analyze, determine, and document high water elevations which will be used to set roadway profile grade. Determine surface water elevations at cross drains, floodplains, outfalls and adjacent stormwater ponds. Determine groundwater elevations at intervals between the above-mentioned surface waters. 6.2 Pond Siting Analysis and Report Update Pond Siting Analysis and Report done in the Phase I – NEPA Environmental Assessment. 6.3 Design of Cross Drains Analyze the hydraulic design of cross drains. Check existing cross drains to determine if they are structurally sound and can be extended. Document the design as required. Determine and provide flood data as required. 6.4 Design of Roadway Ditches Design roadway conveyance ditches. This includes determining ditch cross sections, grades, selecting suitable channel lining, designing the side drain pipes, and documentation. 6.5 Design of Outfalls Analyze and document the design of ditch or piped outfalls.

The CONSULTANT shall certify utility negotiations have been completed with arrangements made for utility work to be undertaken. 7.1 Kickoff Meeting (Not applicable to this project) 7.2 Identify Existing UAO(s) Identify utilities in the corridor; check with Maintenance for Permits, Sunshine State One Call, Subsurface Utility Engineering (SUE) Report, Design Location Survey, and Existing Plans. 7.3 Make Utility Contacts First Contact: Send letters and two sets of plans to each utility, one set for the utility office, one set each to construction and maintenance if required. Includes contact by phone for meeting coordination. Request type, size, location, easements, cost for compensable relocation, and justification for any utility exceptions. Include the meeting schedule (if applicable) and the design schedule. Include typical meeting agenda. Second Contact: At a minimum of 4 weeks prior to the meeting, the CONSULTANT shall transmit two complete sets of Phase II plans to each UAO having facilities located within the project limits, and one set to the COUNTY Offices as required by the District.
