Summary
Parker's stormwater chapter requires every construction-site operator to use best management practices controlling sediment, silt, and soil discharges to the city's drainage system, with qualified personnel inspecting disturbed and stabilized areas every 14 days or within 24 hours of a half-inch rain event, or weekly. Sites disturbing five or more acres must also file an NPDES notice of intent and a stormwater pollution prevention plan.
All operators of construction sites shall use best management practices to control and reduce the discharge to the city’s drainage system and to waters of the US of sediment, silt, earth, soil, and other material associated with the clearing, grading, excavation, and other construction activities to the maximum extent practicable under the circumstances. ... Qualified personnel (provided by the operator of the construction site) shall inspect disturbed areas of any construction site that have not been finally stabilized, areas used for storage of materials that are exposed to precipitation, structural control measures, and locations where vehicles enter or exit the site, on either of the schedules designated in the CGP (either every 14 calendar days and within 24 hours of a ½ inch rain event, or at least once every 7 days regardless of when it rains).
Full Breakdown
06 of the Parker Code of Ordinances, in the city's Stormwater Regulations chapter, sets the erosion and sediment control standard for every construction site in the city. Division (A)(1) lists specific best management practices operators may use: preserving existing vegetation per approved plans, diverting flows from exposed soils, minimizing off-site sediment tracking and dust, containing spills of paints, solvents, and fuels, keeping building materials like cement and mortar out of the drainage system, and maintaining vegetation and erosion controls in good operating condition. Division (A)(2) requires qualified personnel to inspect disturbed, unstabilized areas, material storage areas, and vehicle entry and exit points on a set schedule: every 14 calendar days and within 24 hours of a half-inch rain event, or alternatively at least once every 7 days regardless of rainfall.
The Department of Public Works can deny a building or grading permit, or occupancy approval, if a site's practices fail to control sediment discharge under division (A)(3). Sites disturbing five or more acres, or part of a common development disturbing five or more acres, must submit a signed NPDES notice of intent to the Department of Public Works at least two days before construction, post TCEQ construction-general-permit signage, and prepare a stormwater pollution prevention plan completed before the notice is filed, per division (B). Smaller sites under five acres instead file a construction site notice under division (C). 08.
Violations & Fines
Civil penalties under section 54.10(A)(3) reach up to $1,000 per day for each violation tied to public safety, drainage, or pollutant-discharge provisions, on top of injunctive relief the city can seek through the County Court of Law of Collin. Criminal violations are strict-liability misdemeanors under section 54.10(B), fined up to $1,000 per violation per day, or $500 per day for falsified monitoring reports or SWPPP records.
