Post Construction Storm Water Management
Best Management Practices (BMPs) in this category address storm water runoff from areas of new development and redevelopment. Unlike the temporary BMPs during construction, post-construction BMPs are permanent and are used to control pollution after construction is completed. Post-construction BMPs should be incorporated into development projects and provide for the long-term operation and maintenance of post-construction BMPs.
Bryan’s Storm Water Management Program contains four BMPs in the Post Construction Storm Water Management category including:
- PC-1 : Developer’s Stakeholder Meetings
- PC-2 : Post Construction Ordinance
- PC-3 : Long Term Operation and Maintenance of BMPs
- PC-4 : List of Water Quality CIP Projects
Numerous studies have documented that storm water runoff from developed areas contributes significant amounts of pollution to lakes and streams. The increase in impervious surfaces such as rooftops, roads, and parking lots can increase urban runoff and have a detrimental impact on aquatic ecosystems due to increased concentrations of sediment, nutrients, pesticides, heavy metals, pathogenic bacteria, and petroleum hydrocarbons. The best way to reduce the negative effects of storm water from new development is to use BMPs to treat, store, and infiltrate runoff onsite before it can affect downstream waterbodies. Innovative site designs that reduce impervious area and low impact development practices may be used to reduce storm water runoff and improve water quality.
The City of Bryan will inspect construction sites during construction and after construction has been completed to assure compliance with the Stormwater Management Ordinance. The following checklist will be used to facilitate the inspection:
Ordinance No. 1887
Sec. 46-143 Review and Modification of Best Management Practices
- Any person engaged in activities or operation, or owning facilities or property, which will or may result in pollutants entering the MS4 or waters of the United States, shall implement BMPs to the extent they are technologically achievable to prevent and reduce such pollutants. The owner or operator of a regulated facility shall prove reasonable protection from accidental discharge or prohibited materials or other wastes into the MS4 or waters of the United States. Practices implemented to prevent accidental discharge of prohibited materials or other wastes shall be provided and maintained at the owner or operator’s expense.
- The city does not maintain a list of required or approved BMPs for regulated facilities. The administrator may request facilities to demonstrate the effectiveness of implemented BMPs. Suggested BMPs and a list of prohibited BMPs will be maintained in the B/CS Drainage Design Guidelines.
- The administrator may require an operator of a regulated facility to modify its BMP if the BMPs do not provide effective protection from accidental discharge of prohibited materials or other wastes from entering into the MS4 or waters of the United States.
- The deficiencies in a facility’s BMP will be communicated in writing, and the administrator will provide the operator a reasonable amount of time to make the necessary changes in the BMPs.
