Stormwater Quality Coalitions

While LJA’s Storm Water Compliance division offers a variety of services to our clients, one of our primary areas of expertise is in assisting entities in complying with stormwater discharge permits. Most of our existing Municipal Separate Storm Sewer System (MS4) clients are covered under the TPDES General Permit No. TXR040000. When this permit was originally issued by the Texas Commission on Environmental Quality (TCEQ) on August 13, 2007, our team sought to develop a strategic approach for our clients that would not only achieve a high level of effectiveness and compliance, but could also be utilized by multiple entities in a common geographic area. The result was the development of shared stormwater management programs and the formation of Stormwater Quality Coalitions across the state.

To date, our team has helped form a total of eight coalitions and currently manages stormwater management programs (SWMPs) for more than 40 MS4s in the states of Texas and Louisiana. As part of LJA’s role, our environmental scientists and technicians provide full implementation services including the development of SWMPs, public education programs, outfall mapping/inspections, municipal facility inspections, construction site inspections, TCEQ stakeholder representation, TMDL compliance, annual report development, and audit representation.

Of the eight Stormwater Quality Coalitions we helped develop, our team is still currently managing seven of them:

  • Brazoria County
  • Jefferson County
  • Orange County
  • Hardin County
  • Fort Bend County
  • Montgomery County
  • North Austin

Our largest coalition is the Brazoria County Stormwater Quality Coalition, which has a total of 11 entities: City of Lake Jackson, City of Richwood, City of Clute, City of Freeport, City of Angleton, City of Alvin, Brazoria County Conservation & Reclamation District No. 3, Angleton Drainage District, Brazoria Drainage District No. 4, Velasco Drainage District, and Brazoria County. In order to educate the citizens in these communities about the importance of stormwater quality, the TCEQ requires that each regulated entity implement a public education program. The program we implemented in Brazoria County has consisted of numerous brochures, development of a stormwater quality website, production of public service announcements, development of guidance documents, contractor training seminars, and holding public meetings. Additionally, as part of the field services our environmental team provides, LJA has mapped over 1,200 outfalls and inspected more than 1,000 construction sites for the Brazoria County Stormwater Quality Coalition since implementing their SWMP in 2008.

The coalition approach has proven throughout the years to provide our clients with a range of benefits including cost savings and overall compliance with permit regulations.
