Core offering

Tully Consulting Group provides stormwater management and civil engineering consulting services to construction contractors and infrastructure project owners in California. The firm specializes in Stormwater Pollution Prevention Plan (SWPPP) and Water Pollution Control Program (WPCP) development, field inspections, Qualified SWPPP Practitioner (QSP) and Qualified SWPPP Developer (QSD) services, and regulatory compliance under the Construction General Permit, Industrial General Permit, and Section 401/404 permits. Services are delivered directly to clients on construction sites within a 2-hour radius of Dixon, California, with plan development services available statewide.

Product overview

Tully Consulting Group is a stormwater management and civil engineering consulting firm that operates as a single unified service offering rather than a platform-plus-modules architecture. The company's core portfolio centers on SWPPP/WPCP plan development and inspection services, supported by specialized capabilities in QSP/QSD services, 401/404 permit compliance, Caltrans compliance, and stormwater civil engineering. The company provides these services primarily within a 2-hour radius of Dixon, California, serving construction and industrial clients throughout Northern California.
