Lowell FAQ
Do I need a stormwater permit for a new driveway?
Only if the combined disturbance exceeds 5,000 square feet. Smaller projects still must avoid directing runoff onto neighbors or streets.
Can I wash my car in the driveway?
Occasional residential car washing is allowed, but commercial washing that discharges to the storm drain is considered an illicit discharge.
Newton FAQ
What triggers stormwater review in Newton?
Creating more than 1,000 square feet of new impervious surface triggers DPW Engineering stormwater review. Projects disturbing over 1 acre also require state SWPPP filing.
Can I drain my pool to the storm drain?
No. Chlorinated or chemically-treated pool water is an illicit discharge. Dechlorinate water for 2-3 days and drain slowly to vegetated areas, or contact DPW for guidance.
