Stormwater Management

The Stormwater Management Division is responsible for administering the city's Stormwater Management Program (SWMP). The goal of the program is to implement city-wide practices that improve the quality of stormwater runoff before it enters the drainage system and other downstream waterways. The SWMP is state- and federally-mandated under the Clean Water Act, which requires municipalities (such as Deer Park) to obtain a permit through the Texas Commission on Environmental Quality.

The division also manages the city's Municipal Drainage Utility System, and assists the Engineering Division with in-house construction projects related to the drainage system.

Stormwater Management Program
The City of Deer Park currently operates its drainage system as a Municipal Separate Storm Sewer System (MS4) under regulations issued by the Texas Commission on Environmental Quality (TCEQ). These regulations require municipalities to develop and implement a Stormwater Management Program that includes the following six Minimum Control Measures:

The City of Deer Park's Stormwater Management Program (SWMP) is approved through the TCEQ under General Permit TXR040000, which covers almost every municipality in Texas. This permit expired in 2012 and has yet to be renewed, which means the city must continue to operate under the terms of the expired permit until the renewal permit becomes effective. At that time, the city's program will be revised and updated to comply with the terms of the new permit.

Municipal Drainage Utility System / Fee
On September 18, 2012, ordinances establishing a Municipal Drainage Utility System were adopted. A Municipal Drainage Utility System is a user fee based funding program for municipal drainage management. This is a common funding mechanism throughout Texas, and the funds may only be used to cover appropriate costs related to the city's drainage system.

The following information further describes the system, including the ordinances creating the system and associated rate structure, frequently asked questions, and presentation slides shown during the public hearings:
