Planning & Zoning Board July 10, 2002 Page 15 APPROVED MINUTES issue with the Public Safety Department a nd the Centennial Lakes Fire Department and determined that there are no access concerns with the proposed layout. Staff was also recommending that the appli cant provide a street stub alignment to the south of the development in th e approximate location of Street G. This would allow for a future connection with East Holly Drive. The 2001 Transportation Plan identified East Holly Drive as a future Minor Collector a nd proposes its future connection with Holly Drive to the west and southerl y to Ash Street (County J). While these projects were not planned in the near term, it would be prac tical to reserve the option to connect this subdivision to Holly Street in the future. It appeared that an alignment option was available that would minimize impacts to exis ting properties to the south. It was likely that the connection would not be made un til development takes place to the south. Street Width. In response to comments r eceived by Rice Creek Watershed District the Developer was requesting a reduction in the City’s standard street width to reduce impervious surface. The City currently requires a thirty-two (32) f oot street width. The developer was requesting a twen ty-nine (29) foot width. Section 302 of the City Code states that the City Council may permit varia tions from the street construction standards. Staff had evaluated the request and determined that the proposed tw enty-nine foot width would be sufficient to handle local traffic need s within the development. However, it did appear that parking would need to be limited to a single side to insure emergency vehicle access. Additionally, the reduction in street width coupled with a curvilinear design of the subdivision’s streets ma y reduce visibility of on-st reet pedestrian movements. Sidewalks along Street A and Street B may be necessary to alleviate this concern. The Environmental Board recommended reducing the street width. The City Council had discussed the issue and requested a recomm endation from the Planning & Zoning Board. Grading and Drainage. The Ci ty Engineer had completed review of the Grading and Drainage Plan. A Rice Creek Watershed District (RCWD) Land Development Permit was also required. The City’s Local Water Management Plan calls for the minimum floor elevation, including basement to be 4 feet above th e groundwater, 4 feet above the normal water level, or 2 feet above the 100-year flood elevation, whiche ver was greatest. The plan appears to satisfy these requirements base d on the proposed normal and high water levels. The developer was currently monitoring exis ting groundwater elevations for verification. Final adjustments would be made with the final grading plans. Mitigation sites were proposed to be fenced off after grading was completed to restrict construction traffic. If soils are to be brought to the site they mu st be consistent with existing soil types. Utilities. The City Engineer has completed re view of the Utility Plans. Sanitary Sewer was proposed to be extended to the site from its existing location in Sherman Lake Road, north of Birch Street. Water would be pr ovided by connection to the existing 16" trunk water main lying adjacent to the property on th e south side of Birch Street. The water
