II appears there could be potential drainage problems with the drainage/grading design. The <br />proposed drainage design has subStanlial amount of site runoff flowing from the driveway <br />entrances into County Road D and Cleveland Avenue, Runoff from the site.into the <br />roadways should be limited by modifying the proposed grade or by adding eatchbasins. <br /> <br />There is also a concern of potential flooding of the properties to the north from the site runoff <br />via the ditch on the nonh ~ide of the property, An alternative collection area could be a swale <br />in Ihe boulevard at the intersection corner wilh an oullet piped to the e~isting stonnsewer, <br /> <br />The developer should submit existing and proposed drainage calculations for the site runoff <br />to the City Engineer for review. <br /> <br />2. Rice Creek Watershed District will require the developer to apply for a drainage permit and <br />provide for stOllJJwater runoff lrealmcn!, <br /> <br />3, The developer should submit a detailed utility plan, <br /> <br />4. Details are not dear on the heighls of the proposed retaining walls, Some of the taller <br />sections of wall will require safety railings. <br /> <br />5. The proposed area drain in the lower level will be required to drain into the storm drainage <br />system. A detail of the .connection should be included in the utility plan, It appears tbat a <br />sump pump will be required for Ihis drain, This shall not he connected to the sanitary sewer <br />scrVJCC. <br /> <br />6. The ramp on the west side of the proposed building is vcry ste,ep at 12.75%. This ramp <br />should not be used for public access, <br /> <br />TOTAL P,Ol <br />
