Preliminary plat for eight‑lot Pat Wilson subdivision reviewed; detention basins expected to reduce peak flows

Planning staff presented a preliminary plat on May 11, 2026 for the Pat Wilson Construction property (behind Warren Rule Electric) showing a proposed eight‑lot subdivision with a 50‑foot right-of-way and a cul‑de‑sac.

Tyler summarized the hydrology work and the proposed stormwater controls: the north detention basin reduces modeled peak flow on that outfall from 41.42 cubic feet per second (existing) and a projected 44.58 CFS after development down to 29.75 CFS (approximately a 33% reduction). The south basin reduces a post-development projection of about 41.18 CFS down to 28.76 CFS (about a 30% reduction). Tyler said the lots have been cleared with utilities staff for septic rather than public sewer. He also noted the smallest lot on the plat is about 1.128 acres.

Commissioners and staff discussed whether Electric Avenue should be allowed to be a through street to School Street; staff noted that changes to existing rights-of-way or closures would require City Council action by ordinance and suggested staff would research record plats and historic right‑of‑way status to provide clarity. One commissioner recommended that Electric Avenue not be a through street to avoid adding traffic to narrow School Street; another observed historic platting makes legal changes more complex.

This item was presented as preliminary; no formal commission action was required at this meeting. Staff asked the commission to flag concerns for follow-up and offered to coordinate with the developer and engineer on any changes prior to a formal plat application.
