Mansfield FAQ
Can I drain my pool to the Mansfield street in my yard?
Pool water containing chlorine or salt should not be discharged to the storm drain. Dechlorinate and slowly release to a pervious area on your own lot to avoid an illicit discharge violation.
What size project needs a stormwater plan in Mansfield?
Construction or land disturbance of 1 or more acres requires a TCEQ TXR150000 permit and a full SWPPP. Smaller sites still must prevent sediment migration beyond property lines.
North Richland Hills FAQ
Can I drain my pool into the street in North Richland Hills?
No. Chlorinated pool water must be dechlorinated before discharge and should generally go to the sanitary sewer or be allowed to evaporate. Draining to the storm drain is an illicit discharge violation.
Do I need a stormwater permit for a single-family home build?
Only if the total disturbed area on the lot or common development is 1 acre or more. Smaller individual lots typically rely on the builder's overall subdivision SWPPP.
