He said the pond is no longer needed and plans now call for storm water to be drained from the complex by extending a sewer line beneath I-675 to the east.
Council voted 5-0 to approve the amended plan with 17 conditions. Oberer said Costco, “which I still cannot name due to confidentiality agreements, is amenable to all of them but the 17th,” which had to do with the 1.16 acres.
Council members and city planner Steve Feverston worked out a reformulated condition that would provide the applicant with more options so the plan can advance. Feverston said Costco plans more total green space than the city requires.
Mayor Mark Kingseed told Oberer city officials are “very impressed by what’s coming. We want to work with you to make it happen.”
A retaining wall that will be constructed between the large retail tenants of Cornerstone and a planned residential quadrant to the north and east will now likely be reduced from a maximum height of 23 feet to 10 feet, Oberer said.
The Centerville Planning Commission will consider the first specific site plan for the Costco Cornerstone store during its next meeting on Tuesday, Oct. 29.
Also Monday night, city council approved a preliminary plan by the Centerville Development Group for 65 acres bounded by Paragon, Sheehan and Social Row roads.
That subdivision will include a senior care complex called Randall Residence at Yankee Trace, 84 independent-living condos in 21 “fourplex” buildings and, on the north, a street to be called Sawgrass Boulevard linking Sheehan and Paragon.
Phase two, north of Sawgrass and bordering the current Yankee Trace golf course community, will be devoted to detached single-family homes of similar design and materials.
Architect John Roll said Randall Residence at Yankee Trace would include 46 independent-living units, 72 assisted-living units and 32 memory-care units in separate “pods” of the main facility.
Randall Residence also built a senior community in Tipp City and plans another in Oakwood.
