North Richland Hills, TX Environmental Rules: Erosion Control (2026)

Erosion control in North Richland Hills is enforced through the city's Subdivision Regulations, Building Code, and MS4 stormwater program. All construction activity, regardless of size, must prevent sediment from leaving the site. Common required BMPs include perimeter silt fence around disturbed areas, inlet protection (gravel bags, silt socks, wattle rings), a stabilized construction entrance at each access point, tracking control to prevent mud on public streets, temporary seeding or mulching on exposed areas idle for more than 14 days, and protection of existing trees and vegetation. Projects disturbing 1 acre or more must submit a Stormwater Pollution Prevention Plan (SWPPP) under the TCEQ Construction General Permit and have a qualified person inspect BMPs at least weekly and within 24 hours of rainfall over 0.5 inches. Slopes steeper than 3:1 require additional stabilization measures such as erosion control blankets, hydromulch, or sod. Permanent stabilization with 70 percent vegetative cover or approved hardscape is required before the stormwater permit is closed. Deposited sediment on streets must be cleaned up immediately. Violations can result in stop-work orders.
