Full Breakdown

Added December 22, 2005 by Ch. No. 17, requiring "best management practices for water quality control, which in combination are demonstrated to reduce the average annual total suspended solids in post-development runoff by 80%," with stricter standards where a project sits in a drinking-water watershed or an impaired 303(d)-listed watershed. Plans must also control peak discharge rates for the two-year, ten-year, twenty-five-year, and one-hundred-year storm events to predevelopment levels, and size conveyance systems to handle a twenty-five-year storm without erosive flows. 19 layers on calculation and narrative requirements, from subbasin impervious-surface area to a full site description and BMP justification.

20 don't end at construction: facilities need a written maintenance agreement recorded in the City's land evidence records, a maintenance schedule naming the responsible party, and regular City inspections.

Violations & Fines

A stormwater facility that isn't built, operated or maintained as approved can draw a written notice of violation; if uncorrected within 30 calendar days after a five-day temporary-fix window, the City may summon the owner to Municipal Court for a fine of $100 per day the violation continues, plus a lien on the property for remediation costs, under § 410-92.22.

Frequently Asked Questions

When does Pawtucket require a stormwater management plan?
Whenever a project needs development plan review under § 410-15.1, or whenever it adds more than 300 square feet of new impervious surface, per § 410-92.16. That second trigger catches many smaller additions and driveway expansions that wouldn't otherwise need planning review.
What water quality standard must a Pawtucket stormwater plan meet?
Section 410-92.17 requires best management practices demonstrated to cut average annual total suspended solids in post-development runoff by 80%, with higher standards required in drinking-water supply watersheds or waters already on the state's impaired 303(d) list.
What happens if a stormwater facility isn't maintained?
The City sends written notice by certified mail; the owner gets five days to make a temporary fix and 30 days to complete repairs. If that deadline is missed, § 410-92.22 allows a Municipal Court fine of $100 per day plus a lien on the property for cleanup costs.
