Review File: Country Club Hills Preliminary Plat Request Engineering Review Page 2 of 3 The proposed new development was estimated to consist of 162 single family residential units. This number included the 85 lots proposed in this Plat. Based on the traffic analysis conducted the recommendations and conclusions are: No immediate improvements are needed on roadways around the development area. The lots in this plat were included in this traffic analysis, a separate study is not required. Grading and Drainage Plans: A final grading and drainage plan has been prepared for this subdivision by Anderson Passe & Associates, P.A. Staff offers the following comments on this plan: 1. Lot corner elevations need to be provided on all lot corners and along the centerline of drainage swales which do not coincide with common property lines. The 100 year high water elevations for ponding areas and the FEMA 100 year flood elevations are shown on the plan. All lowest floor building elevations must be two feet above the highest elevation noted. 2. Grading plan sheets at 1" = 50' must be added to the set. 3. A tabulation of lot elevations with minimum floor elevations and adjacent pond high water levels must be added to the plan. 5. The maximum slope should not exceed one foot vertical to four feet horizontal. . 6. The font size/ pen weight of labels must be increased to make plan readable. 7. Sidewalks are generally shown adjacent to the streets. Sidewalk must be added to Sapphire Street NW between 160th Avenue NW and 161st Avenue NW. 8. There are existing homes on lots 1-4, Block 4, Sweetbay Ridge. The grading for lots 2-6 Block 6 of Country Club Hills must maintain the drainage pattern established when the homes were constructed. Larger drainage and utility easements may be required on the new lots A permit from the Lower Rum River Water Management Organization (LRRWMO) will be required. There are wetland impacts associated with this project, additional review time will be required for LRRWMO permit approval. The Sweetbay Ridge project created a wetland mitigation area in area of wetlands 3 and 4. The mitigation area was not maintained, the new permit will include upgrading this wetland mitigation area. Utilities: All lots are proposed to be served by municipal sewer and water. Construction plans and specifications are subject to review of the City Engineering Department. The sanitary sewer in 159th Avenue NW is a trunk line designed to serve properties west of Variolite Street. This line will be eligible for trunk credit. Park Dedication: The park dedication shall be satisfied with a cash payment as was recommended for the preliminary plat of Sweetbay Ridge.
