Commission backs 16‑lot Thompson Street redevelopment with conditions after neighbor concerns

The Alpharetta Planning Commission on Aug. 7 recommended approval of a rezoning and two variances to permit a 16‑unit for‑sale residential development (nine detached homes and seven townhomes) at 272 and 276 Thompson Street. The commission forwarded the rezoning to City Council for final action on Aug. 25 with 27 conditions that address design, stormwater, tree protection and connectivity to the Alpha Loop.

The developer requested rezoning from R‑12 to Downtown Live/Work (DTLW) and variances to reduce a downtown local‑street right‑of‑way from 50 to 40 feet and to modify the downtown requirement that street‑facing detached garages be recessed 20 feet behind the front facade. Planning staff said the proposed density is 7.88 dwelling units per acre (below the 8‑unit‑per‑acre base for DTLW) and that the project provides 68 parking spaces where downtown code requires 40.

The site plan shows a new private street and a private alley serving the units, sidewalk on one side of the new street, an 8‑foot planter and 8‑foot sidewalk along Thompson Street, and a northern 40‑foot tree‑save area reserved for the Alpha Loop. Staff said the applicant will be required to dedicate a minimum 20‑foot public right‑of‑way or easement for the Alpha Loop; if the city has an approved Alpha Loop design in time for construction, the developer would construct the Loop and could receive impact‑fee credits; otherwise the city will construct the Alpha Loop later.

The staff report and the applicant’s presentation addressed stormwater and tree‑preservation measures. The applicant agreed to design the stormwater system to discharge no more than 90% of the current (pre‑development) rate and to use a level spreader or an approved alternative at the discharge point to reduce erosion downstream. Staff also required construction techniques to limit impacts to existing trees and restricted encroachment into critical root zones.

Academy Park Homeowners Association representatives met with the developer before the hearing and expressed concerns about erosion of the adjacent Goswift Creek, tree wind damage during construction, guest parking and a request for an 8‑foot decorative fence along the common boundary. The developer agreed to an 8‑foot decorative fence with a maintenance gate, consistent with similar commitments on nearby projects, and to other design and stormwater measures that were written into conditions 26 and 27.

At the public hearing several nearby residents opposed the project, citing concerns about increased runoff to a detention pond and park across Thompson Street, limited nearby parking in an already busy corridor, and traffic and speeding on Thompson Street. The applicant and staff replied that runoff from the site will discharge north (not to the detention pond across Thompson Street), that each dwelling includes two garage parking spaces plus driveway capacity (code‑compliant 18‑foot minimum driveways) and that the site’s parking provision (68 spaces) exceeds downtown requirements. The developer said the project will be constructed to allow fire and emergency apparatus access even if a vehicle is parked on one side of the private street.

Design conditions require four‑sided architecture and DRB approval; decorative project entrance paving and crosswalk treatments; central amenity landscaping and seating; plantings to encourage historic downtown character; interparcel access for future connections; HVAC and garbage screening; and a limit of no more than 10% of units available for rent, recorded in HOA covenants.

After deliberation the commission unanimously recommended approval with conditions and forwarded the item to City Council on Aug. 25.
