The minutes and transcription were approved after having been previously forwarded to each member. NEW CONSTRUCTION – SINGLE FAMILY RESIDENCE – 111 CRANDON DRIVE

2 Lauren Strutman, project architect, was in attendance at the meeting. Also in attendance were David Volz, civil engineer and Scott Mehlman, owner/developer.

Louis Clayton explained that the proposed project consists of the construction of a 3,977-square- foot (excluding the basement) single-family residence with an attached, rear-entry, at-grade 819- square-foot garage. The height of the proposed residence is 29 feet 2 1/8 inches as measured from the average existing grade to the mean height of the roof. The plans show the HVAC units located in the southwest corner of the property adjacent to the driveway and screened by a wood fence. Trash and recycling receptacles will be stored in a 40-square-foot enclosure located in the southwest corner of the site adjacent to the driveway and screened by a wood fence and gate. The Clayton Gardens Urban Design District limits impervious coverage to 40 percent of the total lot area and allows an increase in impervious coverage based on the garage placement. For this project, the allowable impervious coverage may be increased to 55 percent for the inclusion of an attached, at-grade, rear-loading garage. The existing impervious coverage on site is 26.9 percent. The new plans increase the impervious coverage to 48.3 percent, which is less than the maximum allowable impervious coverage. The existing storm water runoff, according to the MSD 15 year, 20 minute calculation, is 0.48 cubic feet per second (CFS). The proposed runoff is 0.57 CFS, which represents an increase in 0.09 CFS. To mitigate the increase in storm water runoff, downspouts on the south side of the home will be piped to a dry well in the front yard. Downspouts on the north side of the home will be piped to a pop-up bubbler located in the front yard. The Public Works Department finds the storm water plan acceptable, with the condition that the dry well in the front yard be sized to handle the volume of water being discharged by the sump pump. Louis noted that this is the first project that is subject to the City’s recently adopted Trees and Landscaping Regulations. For this site, the regulations require 46 percent tree canopy lot coverage through the preservation and/or planting of trees. The existing tree canopy lot coverage is 75 percent. The proposed tree canopy lot coverage is 75 percent, which includes the preservation of one existing site tree and the planting of 13 new trees. Eight of the new trees (61.5 percent) will be Missouri Natives. One street tree will be removed which will require a payment of $684 into the City’s Forestry Fund prior to removal. According to the City’s contracted landscape architect, the proposed landscape plan provides a variety of trees, shrubs and perennials that are consistent with the character of the surrounding neighborhood. The landscape plan needs to be revised to integrate the proposed HVAC enclosure into the landscape design and to fill in missing foundation plantings on the north side of the home. Exterior lighting is proposed at the rear door and garage. All exterior lights will be 75 watts or less. Louis stated that the height, setbacks, and impervious coverage as proposed are in conformance with the requirements of the R-2 Single Family Dwelling District and the Clayton Gardens Urban Design District. Storm water will be adequately managed on site, and the landscape plan features a variety of trees, shrubs and perennials that are consistent with the character of the surrounding neighborhood. Staff is of the opinion that the project meets the criteria for site plan approval and recommends approval with the following conditions, to be approved by staff prior to the issuance of a building permit -

by the sump pump.
