WITNESSETH: Whereas, the City of Fayetteville is planning to have drainage studies conducted in two areas of the City of Fayetteville that are currently experiencing problems with flooding and Whereas the City of Fayetteville's forces are fully employed on other urgent work that prevents their early assignment to the aforementioned work; and Whereas, USlnfrastructures' staff is adequate and well qualified and it has been determined that its current work load will permit completion of the plans for the project on schedule; Now therefore, it is considered to be in the best public interest for the City of Fayetteville to obtain assistance of USlnfrastructures' organization in connection with said engineering services. In consideration of the faithful performance of each party of the mutual covenants and agreements set forth hereinafter, it is mutually agreed as follows: SECTION I - EMPLOYMENT OF ENGINEER The City of Fayetteville agrees to employ USlnfrastructure, Inc. to perform, and USlnfrastructure, Inc. agrees to perform, professional engineering services in connection with the project set forth in the Sections to follow; and the City of Fayetteville agrees to pay and USlnfrastructure, Inc. agrees to accept, as specified in the Sections to follow as full and final compensation for work accomplished in the specified time. SECTION II - SCOPE OF THE PROJECT The scope of the project covered by this agreement includes the engineering services required to perform the following tasks in the priority order listed. Area 1 — Drainage Study of the Hamestring Creek Basin (Upstream of I-540) Area 2 — Drainage Study of the Shenandoah Trailer Park Area A. Study and Report Preparation The following is a numerical outline of the major work items to be performed for each Area: 020922—Contract Page 1 of 13 NOM r • • Area 1 — Drainage Study of the Hamestring Creek Basin 1. Identification of Major Sub -basins and Major Tributaries in the Basin Sub -basins and major tributaries in the Hamestring Creek Basin will be identified using previous work performed by City staff, existing topographic information and aerial photography. Basin boundaries will be modified when existing streets and storm sewers alter natural flow patterns. Roadway and subdivision plans of record will be referenced in order to locate storm sewers and to determine their effects on basin boundaries. In some cases, field verification will also be required in order to identify exact basin boundaries. a. Tasks 1. Identify major basin and sub -basin boundries 2. Identify soils types affecting runoff 3. Identify land use/land cover (current and future) using the City's current Land Use Map b. Deliverables 1. Basin map with all sub -basins and tributaries identified 2. Identify Existing Drainage Problems Drainage problems existing in throughout the basin will be sought and identified. Descriptions and photographs of problems will be presented. a. Tasks 1. Define "drainage problems" to be addressed 2. Conduct public meeting(s) to discuss problem areas 3. Review property owner complaints 4. Site visits and photographs 5. Interview property owners b. Deliverables 1. Descriptions and photographs of each drainage problem location 2. Summary of interview of property owner(s) complaints 3. Inventory of Drainage Structures Along Definable Drainage Channels Drainage structures throughout these basins will be inventoried by City supplied mapping and field verification. Structural inventory sheets, developed by USInfrastructure, Inc., will include a photograph, size, shape, material, and functional condition of each structure. Recommendations for maintenance of each structure will also be provided in the structural inventory. a. Tasks 020922—Contract Page 2 of 13 •• I . Transfer existing city structure survey information 2. Field measurements and photographs of structures b. Deliverables 1. Structure inventory sheets 2. Recommendations for maintenance and/or improvements 4. Hydrologic Analysis The hydrologic analysis of the Hamestring Basin (Upstream of I-540) will be preformed using HEC -HMS modeling software developed by the U.S. Army Corp of Engineers. Land use/land cover and soils information will be used to develop curve number and lag times for each sub - basin. Basin models will be constructed according to Fayetteville digital topography and Drainage Manual requirements to represent land use under current and future conditions in order to illustrate existing conditions and the effect of continued development in the basin. This work will be compared with previous work performed by City staff. Rainfall simulations will be performed for 2-, 10-, 25-, 50-, and 100 -year storm events. HEC -HMS uses basin characteristics to predict runoff quantities that will be produced for given storm events. Runoff quantities and hydrographs for each sub -basin will be generated for 2-, 10-, 25-, 50-, and 100 -year storms for current and future land use conditions. Effects of regional and onsite detention will also be simulated. Model results will be evaluated and compared with existing FEMA and Corp of Engineers data. a. Tasks 1. Review previous work performed by City staff 2. Develop sub -basin curve numbers 3. Develop sub -basin lag times 4. Construct HEC -HMS model 5. Develop hydrographs for sub -basins 6. Evaluate model results and troubleshooting 7: Compare model results with FEMA results b. Deliverables 1. Digital copy of model 2. Hydrographs for each sub -basin 3. Tabular model results 4. Comparision of model results with existing data 5. Comparison of model results with FEMA results 5. Hydraulic Analysis The hydraulic analysis of the Hamestring Creek Basin will be performed using HEC -RAS modeling software developed by the U.S. Army Corp of Engineers. A basin model will be developed to represent the definable stream threads in the basin. The model will be 020922—Contract Page 3 of 13 • • constructed using cross sections developed from existing topographic maps, surveyed cross sections (provided by City staff), City as -built plans and structure dimensions collected during field surveys. This model will use the flows generated in HEC -HMS to forecast floodwater depth and width (encroachment). Model outputs will be used to evaluate whether existing structures will be inundated during projected storm flows and to locate current and future problem areas throughout the basin. Model results will be evaluated and compared with existing City, FEMA and Corp of Engineers data. a. Tasks 1. Review existing city cross section survey information 2. Build HEC -RAS model 3. Evaluate model results and troubleshooting 4. Identify problem areas b. Deliverables 1. Digital copy of model 2. Graphical model results 6.

Preliminary results of the hydraulic analysis will be reviewed with the city staff prior to selection of improvement altematives Improvements may include channel modifications, structure modifications, maintenance, or replacement, and regional or onsite detention. Comparsions will be made between open channels versus closed culverts. Review of recommended improvements will first evaluate existing designs. Physical modifications to the drainage system for each altemahve will be modeled using HEC -RAS. Selection of the most appropriate improvement will not only consider onsite conditions, but will look at drainage effects throughout the basin, upstream of Interstate 540. Stormwater quality issues such as those facing the City for NPDES Phase II requirements will also be considered. Finally a preliminary cost analysis will be preformed for each alternative.

Basin models will be constructed according to Fayetteville digital topography and Drainage Manual requirements to represent land use under current and future conditions in order to illustrate existing conditions and the effect of continued development m the basin. This work will be compared with previous work performed by City staff. Rainfall simulations will be performed for 2-, 10-, 25-, 50-, and 100 -year storm events. HEC -HMS uses basin charactenstics to predict runoff quantities that will be produced for given storm events. Runoff quantities and hydrographs for each sub -basin will be generated for 2-, 10-, 25-, 50-, and 100 -year storms for current and future land use conditions. Effects of regional and onsite detention will also be simulated. Model results will be evaluated and compared with existing FEMA and Corp of Engineers data. a. Tasks 1.
