Council approves final plat for Korynsky Addition; drainage relocation to remain private

The Evanston City Council approved Resolution 25‑24, authorizing a final plat for the Korynsky Addition, a minor subdivision that combines two lots at the southwest corner of East Hayden Avenue and Grass Valley Drive into a single lot.

Planning staff explained the resulting lot will measure 0.479 acres (about 20,865 square feet) and falls within the city's medium-density residential zoning; the minimum lot size in that zone is 6,000 square feet. Jacobson said the subdivision will convey a small sliver of land — roughly one‑one-thousandth of an acre — to the city where property corners currently encroach into the street radius.

The applicant proposes to relocate an existing drainage line that currently sits between the two lots; staff said the relocated line will run along the back of the new lot to East Hayden and then down to a city storm basin. Jacobson said the relocated drainage section will remain privately owned and maintained and that the city will not bear installation costs.

Staff recommended approval subject to several conditions, including capping an existing water and sewer service per direction of the public works department (the service may be retained for irrigation if the owner chooses) and providing verification that the plat is recorded with the county. Council discussion included engineering questions about slope and piping; planning staff said the applicant must provide engineered plans and work with an engineer to design the drainage relocation.

The resolution passed by voice vote. Jacobson told councilmembers he understands the property owner plans to build a house next year, but the transcript records that as the owner’s stated timeframe rather than a binding schedule.

The council approved the plat with staff's recommended conditions; further engineering and permitting will be required before site work begins.
