Isleton FAQ
Can I drain my pool into the street?
Not if it contains chlorine or cleaning chemicals. Dechlorinate first or discharge to landscaping to avoid an illicit discharge violation.
Do I need a SWPPP for a house remodel?
Only if the disturbed ground area exceeds 1 acre. Most residential projects fall well below that threshold.

Washing vehicles where runoff enters the storm drain system is discouraged. Use a commercial car wash or wash on a permeable surface like a lawn where water can infiltrate.
Do I need a stormwater plan for a home renovation?
If your project creates or replaces 5,000+ sq ft of impervious surface, you must implement stormwater treatment measures. All construction projects need erosion controls during work.
