Commission recommends subdivision drainage standards to limit lot‑to‑lot runoff and require site certification

City planning staff outlined proposed amendments to Chapter 10 of Springtown’s subdivision regulations intended to tighten lot‑level drainage controls for new single‑family subdivisions. Key elements include engineered grading and drainage for new plats, a requirement that finished pad elevations be at least 6 inches higher than the top of curb, limiting stormwater conveyance across adjacent lots (conveyance may cross only one other lot without a drainage easement), and a site‑certification by a surveyor prior to issuance of occupancy.

Commissioners asked whether the draft language was in reaction to recent storms and about maintenance of existing drainage features; staff said it is not tailored to a single storm but responds to council direction and the city’s comprehensive plan update. Staff also warned that the changes could increase costs for new builds that are not already platted (vested rights apply to existing plats). The commission moved and the recommendation to council was unanimous.
