The height of the proposed residence is 29 feet 3 1/8 inches as measured from the average existing grade to the mean height of the roof. The

2 plans show the HVAC units located at the south side of the home and screened by a 4-foot tall wood fence. Trash will be stored in a 40-square-foot trash enclosure located at the end of the driveway. The trash enclosure will be screened by a wood fence and gate. Louis indicated that 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 25.3 percent. The new plans increase the impervious coverage to 50.6 percent, which is below the maximum allowable impervious coverage of 55 percent. The existing storm water runoff, according to the MSD 15 year, 20 minute calculation, is 0.5 cubic feet per second (CFS). The proposed runoff is 0.6 CFS, which represents an increase in 0.1 CFS. To mitigate the increase in storm water runoff, downspouts on the southern half of the home will be piped to a dry well in the front yard. All other downspouts will be piped to a pop-up bubbler in the front yard. The Public Works Department finds the storm water plan acceptable. The proposed landscape design features a variety of understory trees, ornamental shrubs and perennials that are appropriate for the size of the site and character of the neighborhood. Four trees totaling 64 caliper inches will be removed, and 36 caliper inches require onsite replacement. The landscape plan proposes 53 caliper inches of new deciduous and broadleaf evergreen trees on site. The City’s contracted landscape architect is of the opinion that the proposed trees are suitable for the site. Two existing street trees are shown to be protected and preserved per City guidelines; however, the plans indicate that re-grading will occur which will place fill over the trees’ critical root zones. To avoid potential damage to the street trees, it is recommended that re-grading be avoided within the critical root zones and that the site and landscape plans are revised accordingly. Exterior lighting is proposed at all exterior doors and at the 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 understory trees, ornamental shrubs and perennials that are appropriate for the size of the site and character of the 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:

the approved site plan with St. Louis County and submit proof of recording to the City.
