Jurisdiction Notes

Richardson is home to the Telecom Corridor, a concentration of technology and telecommunications companies along US-75. The city is largely built out and construction activity is predominantly redevelopment, densification, or tenant improvement. The Duck Creek greenbelt system provides valuable open space and drainage function. Richardson spans both Dallas and Collin counties. The city has a well-established stormwater program with active illicit discharge detection and elimination efforts.

Remember: These local requirements are in addition to the TCEQ state construction permit. Both must be satisfied before breaking ground.
