There might be some good news on the horizon for those who live in the Knolls subdivision.

Columbus officials said a new 218-unit apartment complex under construction at the former Kahoots adult nightclub site, 4522 Kenny Road at the southeast corner of Kenny and Henderson roads, is not expected to dramatically affect stormwater drainage at the residential subdivision, whose eastern border straddles Olentangy River Road.

The storm-sewer effluent would flow through an existing line that runs east, eventually crossing Henderson Road on the north side of the Knolls and eventually draining directly into the Olentangy River, according to a map provided by the Columbus Public Utilities Department.

The sanitary sewer also would hook into existing infrastructure travel north and east, eventually connecting to a trunk that would loop back south to the water-treatment plan, said John Ivanic, a spokesman for the public-utilities department.

The development increases the volume of stormwater detention at the site by nearly 3.5 times what it formerly was and would reduce the peak rate of release of storm water by more than 50% in some events, said George Zonders, also a spokesman for public utilities.

Tom Swain, a resident of the Knolls, said he is interested in where the Kahoots sanitary-sewer line's connection will be.

"If it's true that they have a separate trunk line for the sanitary line, that would be a huge relief," Swain said. "But again, I haven't seen any drawings or sketches from the city that would verify that. I am skeptical at this point, I'd guess you'd say."

Residents of the Knolls are uneasy about storm- and sanitary-sewer overflows in the neighborhood that in the past have sent toilet paper and human waste flowing down the streets and through yards.

When those backups and overflows have occurred, city workers have cleaned the mess and sprayed disinfectant.

Another developer wants to build a 402-unit apartment complex on the northwest corner of Olentangy River and Henderson roads, commonly known as the Zimmerman tract.

Representatives from NR Investments, a Florida-based development firm that wants to build the apartments, have stressed they believe there is plenty of sewer capacity to accommodate the apartment complex and it wouldn't affect the ability of the Knolls sewer to effectively remove storm and sanitary effluent.

However, the developer asked that the project to be tabled while sewer-system research is conducted.
