Zoning File #2204 January 14, 1997 Page 4 Grading/Drainage Applicant's grading plan proposes a retention pond within Lot 1 to maintain and treat runoff from development of Lots 1 and 2. The plan provides for a 20’ easement over drainageway that leads to retention pond as requested by engineer (Exhibit G). Note drainage from culvert beneath road flows to the northwest at the north side of roadway and to the southeast to the south side through Lot 5. Drainage does not all flow to the south through Lot 5 as originally assumed in the sketch plan review. The City will ask for a detailed grading plan witli the development of Lot 5 as it relates to both site drainage and driveway. The City Engineer shall review tlie grading plan and size of culvert to be used where drive encroaches drainageway. Private Road Review Exhibit D, Planning Commission Members agreed that the existing drive and amenities should be preserved as much as possible when applying the code standards for an upgraded private roadway at a 24' width. Exhibit G, the Engineer's report and the Long Lake Asst. Fire Chiefs review comments provide alternatives for tiie required upgrade. As for the entrance monuments, the City Engineer recommends that the monuments be relocated to provide a 24' wide opening. In the Asst. Fire Chiefs report, he recommends that the roadway for a distance of 100' west of the entrance monuments be upgraded to a 28' width to allow emergency vehicles to park to one side while another vehicle could freely pass. Both ask that the existing turn at the west end of the retaining w'all be upgraded to facilitate the turning of emergency vehicles. This is now show n on your preliminary plan. The City Engineer has asked that the roadway in between the retaining walls for 500' be expanded to 22’ with curbing. This can be accomplished within the 24' width that exists between retaining walls. Staff also recommends that the cul-de-sac be staked so that staff can determine what trees would need to be removed. There may be a need to adjust location of cul-de-sac to minimize tree removal. Both the Fire Department and the City Engineer recommend the drive be upgraded to a 24' minimum width and a combination of curbing and ditching can be 'vorked out in order to preserve as many of the existing plantings adjacent to the roadway. As already noted above, there is no future extension road leading from the north to the Fullerton property. The cul-de-sac will be approved at a 1,600' length with a potential of 8 possibly 9 residential units to be ser\ed. Lot 4 could be subdivided in the future. Topography and septic limitations will prohibit future subdivision of Lots 1 and 2. Lot 3 with the 30 year covenant that restricts construction within the southwest lakeshore yard will also prohibit future subdivision.
