The minutes were approved, after having been previously distributed to each member. SITE PLAN REVIEW/ARCHITECTURAL REVIEW – NEW SINGLE FAMILY RESIDENCE – 233 LANCASTER

Gabe DeBois, project designer, and Lori Fumagalli, project architect, were in attendance at the meeting.

2 Susan Istenes explained that this is a request for review of the site plan associated with the proposed construction of a new 4,564-square-foot single-family residence (excluding the basement) with an attached, rear-entry, at-grade garage. The height of the proposed residence is 29- feet 7.75-inches as measured from the average existing grade to the mean height of the roof. The plans show the HVAC units located at the north of the home and screened by evergreen shrubs. Trash will be stored in a 53-square-foot trash enclosure located at the rear of the property adjacent to the garage. The trash enclosure will be 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 at-grade, rear-loading garage. The existing impervious coverage on site is 26.8 percent. The new plans increase the impervious coverage to 40.7 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 0.6 cubic feet per second (CFS). The proposed runoff is 0.67 CFS, which represents an increase in 0.07 CFS. To mitigate the increase in storm water runoff, downspouts will be piped to an at-grade bio-retention facility in the rear yard. The Public Works Department has reviewed the site plan and finds the storm water plan acceptable. The proposed landscape design features a variety of trees, shrubs, perennials, and ground cover suited for this region. Seven trees totaling 93 caliper inches will be removed, and 85 caliper inches require replacement. Two existing street trees totaling 84 caliper inches will be impacted by construction and are shown to be protected and preserved per City guidelines. The proposed excavation for the bio-retention facility will impact two trees in the rear yard, and the tree chart should be revised accordingly. Additionally, planting should be indicated on the plan to determine how this area will be appropriately covered with vegetation. The landscape plan proposes 92 caliper inches of new deciduous and broadleaf evergreen trees on site including Red Maple, American Holly, Bracken Brown Magnolia, Pink Dogwood, Columnar Armstrong Maple, Sugartyme Crabapple, Kousa Dogwood, Columnar English Oak, and Centennial Holly. The City’s contracted landscape architect is of the opinion that the proposed trees are suitable for the site and that the existing trees to remain are shown to be protected and preserved per City guidelines. Exterior lighting is proposed at the front and rear of the home. All exterior lights will be 75 watts or less. Susan stated that the proposed home is compatible with surrounding homes in the neighborhood. Storm water will be adequately managed on site, and the landscape plan provides for a variety of new trees, shrubs, and groundcover suitable for this region. 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. Staff is of the opinion that the project meets the criteria for site plan approval and recommends approval with the following conditions:

shall record the approved site plan with St. Louis County, and submit proof of recording to the City prior to the issuance of a building permit.
