Chairman Lichtenfeld announced that the order of agenda items will be changed this evening; the “Old Business” (Clayton/Hanley Road project) will go last. SITE PLAN/ARCHITECTURAL REVIEW – NEW CONSTRUCTION – SINGLE FAMILY RESIDENCE – 635 WEST POLO DRIVE

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

Susan Istenes explained that on May 2, 2016 the Plan Commission-Architectural Review Board voted to approve a new single family residence at this location. On February 7, 2017 the owner/applicant provided revised plans for the proposed residence. After review of the changes, staff concluded that the revisions were significant enough to be considered a new submission that would require review and approval by the Plan Commission-Architectural Review Board. The 26,274-square-foot property is located on the west side of West Polo Drive and has a zoning designation of R-2 Single Family Dwelling District. The proposed project consists of the demolition of an existing two-story home and the construction of a two-story, 4,664-square-foot (excluding the basement) single-family residence. The height of the proposed residence is 29-feet 9 5/8 inches as measured from the average existing grade to the mean height of the roof. The proposed HVAC units are located at the rear of the home and screened by a wood fence. Trash will be stored in a 40-square-foot wood-framed trash enclosure located adjacent to the garage. The existing impervious coverage on site is 23.1 percent. The new plans decrease the impervious coverage to 20.7 percent, which is below the maximum allowable impervious coverage of 55 percent. The existing stormwater runoff, according to the MSD 15 year, 20 minute calculation, is 1.28 cubic feet per second (CFS). The proposed runoff is 1.25 CFS, which represents a decrease in 0.03 CFS, and therefore on site stormwater mitigation is not required. Downspouts from the home will be piped to two pop-up emitters in the rear yard. The Public Works Department has reviewed and approved the stormwater management plan. The proposed landscape design provides appropriate landscaping and screening for the proposed home and the character of the neighborhood. The landscape plan shows the removal of 12,795 square feet of canopy coverage. The proposed landscape plan provides a surplus of 49,385 square feet of canopy coverage and meets the requirement for native trees with 33.3 percent. The City’s contracted landscape architect is of the opinion that the proposed trees are suitable for the site. The structural root zones of existing trees are not shown on the Tree Preservation Plan. This can be addressed prior to the issuance of building permits. Exterior lighting is proposed at all doors and the garage. All exterior lights will be 75 watts or less. Director Istenes noted that the proposed home is compatible with surrounding homes in the neighborhood, that stormwater will be adequately managed on site, and the landscape plan provides for a variety of new trees that are suitable for the area. The project meets the setback, height and impervious coverage requirements of the R-2 Zoning District and the applicant has recently submitted approval from the subdivision trustees. Staff is of the opinion that the project meets the criteria for site plan approval and recommends approval with the condition that the Tree Preservation Plan be revised to depict the structural root zones of existing trees to remain.

Ms. Strutman presented a site plan to the members.

Joanne Boulton asked if the house is already gone.

Ms. Strutman replied “yes”.

Ms. Strutman replied “yes”.

Joanne Boulton asked about the existing swimming pool.

Mr. Henke indicated that it has not yet been removed.

Ms. Strutman informed the members that this revised proposal is for a simpler, smaller house; about 600 square feet smaller. She mentioned that Trustee approval has been submitted to staff.

Ms. Volz presented drainage diagrams depicting existing and proposed conditions. He added that less water will go onto the public right of way and that there are two pop-up emitters in the rear yard.

Chairman Lichtenfeld commented that it appears that less water will flow to adjacent properties as well.

Mr. Volz concurred.

Chairman Lichtenfeld noted that there is a lot of greenspace toward the west.

Mr. Volz agreed.

Chairman Lichtenfeld commented that the maps are very helpful. He asked the applicants if they were okay with staff’s recommendation.

Ms. Strutman replied “yes”.

Hearing no further questions or comments, Josh Corson made a motion to approve the site plan per staff recommendations. The motion was seconded by Scott Wilson and unanimously approved by the members.

The architectural aspects of the project were now up for review.

Ms. Strtuman presented a color rendering of the proposed house to the members.

Susan Istenes explained that the height of the proposed residence is 29 feet 9 5/8 inches as measured from the average existing grade to the mean height of the roof. The two-story home to the south (637 West Polo Drive) was constructed in 1930 and is +/- 5-feet 4-inches shorter than the proposed home (as measured from the mid-point of each roof). The proposed residence is one-story along the southern elevation, which will lessen the impact of the height difference between these two homes. The two-story home to the north (619 West Polo Drive) was constructed in 1927 and is +/- 10-feet 8 1/8 inches shorter than the proposed home (as measured from the mid-point of each roof). The Clayton Gardens Urban Design District requires the use of an approved mitigation strategy to lessen the impacts of height differences between existing and proposed houses.
