• <br />Highland Meadows East 2 "d Addn. <br />page 6 <br />Area of Individual Driveways <br />13,569 <br />Total Impervious Surface <br />60,701 <br />Impervious Percentage of Site <br />40.16% <br />Total Pervious Surface <br />90,449 <br />Pervious Percentage of Site <br />59.84% <br />Common Open Space (Lot 21) <br />92,900 <br />Open Space Percentage of Site <br />61.46% <br />Utilities: Sanitary sewer and water service will connect to existing facilities in 79th St. and <br />follow the private drive into the site. Individual units must have individual connections. The <br />City Engineer's report notes that utilities will be private. Upon reconsideration, the sanitary <br />sewer and water utilities in the private drive should be City facilities, just as they would if it were <br />a public street right of way. All of Lot 21 is to be covered by a drainage and utility easement, <br />which provides access to the utilties. <br />Grading and Stormwater Management: Stormwater ponds will be created in the northern <br />portion of the site. Drainage and utility easements will cover the ponds and stormwater facilities. <br />Easements also will be platted along all the external property lines. <br />The project requires the approval of the Rice Creek Watershed District. That review is pending. <br />The City has not received geotechnical information on existing groundwater levels and soils. <br />This must be determined in order to compare lowest floor elevations and soil suitability for <br />construction. This must be ascertained prior to City Council consideration of the application. <br />The project also will require the vacation of an existing ponding easement. The original <br />Highland Meadows East plat included a drainage and utility easement in the northwest corner of <br />the site. The 2 "d Addn. application includes a reconfiguration of the easement and pond. The <br />"pond" existed for several years as a borrow pit for fill for Highland Meadows West areas. The <br />development of the site will correct this. The easement vacation is not a P & Z item. Rather, the <br />City Council holds a public hearing on it. <br />Site Plan, Townhomes <br />Buildings: Architectural drawings inlcude vinyl siding with "optional shakes" and a note: <br />"Exterior to be a combination of brick & vinyl siding at builders option." This is not acceptable. <br />The City's building material standards in the zoning ordinance state: <br />Exterior Building Finish: The exterior of townhome dwelling units shall include a <br />variation in building materials which are to be distributed throughout the building facades <br />and coordinated into the architectural design of the structure to create an architecturally <br />balanced appearance. In addition, townhome dwelling structures shall comply with the <br />following requirements: <br />
