Mr. Hoelzer informed the members that the rear addition to be removed will be replaced with a larger lower level garage and a 2-story living space above. He added that a walk-out under the deck will be provided and he asked that they be allowed to utilize brick on the new retaining wall rather than the concrete.
Chairman Lichtenfeld stated that the project and materials look good.
A sample of the clay tile roof was presented.
Hearing no further questions or comments, Ron Reim made a motion to approve per staff recommendations; adding that staff will need to review and approve the HVAC screening material. He noted the retaining wall will be brick as proposed this evening. The motion was seconded by Craig Owens and unanimously approved by the Board.
SITE PLAN REVIEW/ARCHITECTURAL REVIEW – ADDITION TO SINGLE FAMILY RESIDENCE – 20 CARRSWOLD
Jessica Deem, project architect, was in attendance at the meeting.
Anna Krane explained that the existing one-story home measures 4,503-square-feet (not including the basement/garage) and the proposed project consists of the construction of a 3,076-square-foot two story addition and a 100-square-foot basement garage addition. The project also includes an open covered porch, an open uncovered porch and a new patio. The proposed project square- footage is greater than 50 percent of the existing structure square-footage and therefore requires site plan review. The proposed HVAC units are located along the western elevation of the addition. The existing house will screen the units from the street. The proposed addition will screen the units from the east and landscaping will screen the units from the west and north. Trash will be stored in a 58-square-foot trash enclosure located at the northern end of the existing driveway. The enclosure
10 northern portion of the paver patio, facing the house and below the proposed deck. The retaining wall will support a landscaped area to the north and the existing driveway. The retaining wall will not be visible from the public right-of-way or adjacent properties. It is staff’s opinion that the proposed concrete retaining wall is acceptable and will not negatively impact neighborhood character. The project as proposed is in conformance with the requirements of the R-2 Single Family Dwelling District and the Architectural Review Guidelines. Planner Krane stated that staff is of the opinion that the design and materials of the addition are compatible with the neighborhood and recommends approval with the following conditions:
connect the proposed driveway drain to MSD sewer lines.
Trash will be stored in a 58-square-foot trash enclosure located at the northern end of the existing driveway. The enclosure
11 will be constructed of cedar privacy fencing. The existing total lot impervious coverage on site is 27.5 percent. The plans increase the total lot impervious coverage to 35.3 percent, which is still below the maximum allowed impervious coverage of 55 percent. The proposed plans increase front yard impervious coverage from 32.3 percent to 40.4 percent, which is below the 45 percent maximum allowed for front yard coverage. The existing stormwater runoff, according to the MSD 15 year, 20 minute calculation, is 1.70 cubic feet per second (CFS). The proposed runoff is 1.79 CFS, which represents an increase of 0.09 CFS, and therefore on site stormwater mitigation is required. Downspouts from the home will be piped to one of the three drywell systems proposed on the site. A pop-up emitter will be connected to each of the drywells for overflow. The Public Works Department has reviewed and approved the stormwater management plan. It is the opinion of the City’s contracted landscape architect that the landscape plan provides an attractive planting design of trees, shrubs, perennials and groundcover. The existing canopy coverage on site is 27,576-square-feet.There is an overage of 16,843-square-feet of canopy coverage and the landscape plan exceeds the requirement for native trees at 78.6 percent. The landscape plan requires additional revisions to document existing tree canopies and tree protection measures. The outstanding comments can be addressed with revised plans submitted prior to the issuance of building permits. Exterior lighting is proposed at all addition doors and the garage. All exterior lights will be 75 watts or less. Planner Krane continued by indicated that the proposed project is compatible with the existing home and with surrounding homes in the neighborhood. Stormwater will be adequately managed on site and the landscape plan provides for an attractive design with a variety of trees, shrubs and perennials that are suitable for the area. The project meets the requirements of the R-1 Zoning District. Staff is of the opinion that the project meets the criteria for site plan approval and recommends approval with the following conditions, to be reviewed 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 prior to the issuance of a building permit.
