Permits in East Norman - Lake Thunderbird Watershed Compliance
East Norman, generally east of Sooner Road, drains to Lake Thunderbird - the primary drinking-water source for Norman, Midwest City, and Del City. The lake is on Oklahoma's 303(d) impaired waters list, which triggers stricter stormwater protection requirements under Norman Code Chapter 20.
Practical effect: the disturbance threshold for ESC plans drops from 1 acre (citywide) to 5,000 sq ft in the watershed. Pool backwash water cannot discharge to storm drains. Permanent stormwater BMPs must be sized for the 90th-percentile storm and meet phosphorus removal targets.
