The six phases shall be as defined. Execution of this agreement shall be considered as authorization to proceed with Phase I. Subsequent authorizations shall be required for each additional phase. PHASE I. TOPOGRAPHIC MAPPING ✓ ✓ Prepare topography at a scale of 1'' = 100' and one foot contour interval covering the area designated on Exhibit A attached hereto. Photography for mapping shall be obtained at a scale of 1" = 250' with a 6" Zeiss RMK 15/23 distortion-free aerial camera. Mapping shall be perform©d at a scale of 1" = 50' and simultaneously reduced by pantograph to a scale of 1" = 100' . Mapping will be furnished to the Client in pencil on mylar. No final scribing or drafting will be performed. Mapping will consist of contours only and will not include planimetry such as buildings, fences , roads , and other similar features. Ortho photos will also be furnished covering the area designated on Exhibit A. These will be accurately scaled to match the topographic mapping and will serve to furnish planimetric features. Topographic mapping will conform to the national standards of accuracy. Field control for mapping will be obtained by ground survey methods to an accuracy suitable for preparation of topography to the national standards of accuracy. Bench marks will be established at approximately one-half mile intervals along the west side and north south center lines of sections 30 and 31. Items to be furnished to the Client under this phase will include the following: 1. Topographic manuscript sheets at a scale of 1' = 100' with one foot contours 2. One complete set of contact prints of aerial photography at a scale of 1 ' = 250' 3. One complete set of ortho photo plan sheets at a scale of 1" = 100' 4. Summary of bench mark descriptions and elevations. PHASE II. DRAINAGE AREA REVIEW Phase II provides for the identification of the total drainage area and runoff tributary to the mapping limits identified on Exhibit A. Specific tasks to be performed will include, but not necessarily be limited to, the following: 1. Determine appropriate design frequencies applicable for the project 2. Perform six percolation tests at suitable locations throughout the area 3. Develop design criteria such as runoff coefficients , infiltration allowances, rainfall frequencies , and other pertinent data 4. Perform preliminary runoff computations to determine present flooding conditions 5. ! Analyze Stanley and Sullivan ditches to determine whether ditch overflow into the drainage area is a factor. Also, determine whether use of Sullivan ditch is possible for disposal of runoff from the area -2- Information to be furnished to the Client at conclusion of this phase would consist of flood quantities and routes displayed on an appropriate base map. PHASE III. CONCEPTUAL PLAN DEVELOPMENT Phase III entails the development of the conceptual plan for conveying drainage through and from the mapping area to appropriate discharge points. It is understood that utilization of surface drainage is desired to the maximum extent possible and concepts will reflect this desire. General floodway routings and detention pond locations will be indicated. General descriptions will be applied to elements sufficient to permit differen- tiation between channels, conduits, green ways, at cetera. Detailed sizing of facilities will not be performed during this phase of the work. An exhibit would be prepared illustrating the general features of the drainage network deemed appropriate for solution of flooding problems. Proposed solutions shall be reviewed with and approved by the Client before proceeding with Phase IV. PHASE IV. PRELIMINARY PLAN AND COST ESTIMATES Phase IV shall consist of the development of the detailed preliminary plan and cost estimates. Specific steps to be undertaken include the following: 1. Preparation of final runoff computations based on the conceptual plan approved at the conclusion of Phase III 2. Performance of preliminary soil surveys to ascertain subsurface conditions as a basis for cost estimating 3.
