Truckee Meadows

Structural Controls are engineered methods for controlling and treating storm water runoff preventing water pollution to downstream creeks and rivers.

The Truckee Meadows Structural Controls Design Manual (2008) - Updates & Errata (2008) - provide Guidance for Source and Treatment Controls for Storm Water Quality Management.  Hard copies of handbook are available at the City of Reno Community Development or Public Works Offices in City Hall, 1 East First St, Reno.  If you are just starting to plan your site, please first review the planning-focused Low Impact Development Handbook. *Please note that these handbooks are under technical review (2014) and update. When complete, they will be posted here, please check back in the fall for updates.

We also provide a set of interactive Standard Design Guidance Worksheets for proper sizing of project features to treat the representative storm water quality effectively.  *The worksheets are also being updated and will be reposted here when complete.

This program implements structural best management practices (BMPs) at areas of new development and redevelopment.  Program components include new policies and procedures, ordinance revisions, drainage manual revisions, training for staff, project designers and developers, database tracking, complaints reporting and public education and outreach on structural BMPs. Our goal is to provide written guidance and training to local government staff, project designers, developers and structural BMP owners regarding the design, operation, inspection and maintenance of structural controls.  Existing jurisdictional drainage design manuals (Reno Public Works Design Manual and Truckee Meadows Regional Drainage Manual) have been revised to include a new chapter on structural controls for stormwater quality. The new chapters include technical guidance on the selection, site, sizing, operation and maintenance of structural controls designed to enhance stormwater quality. 

Tree Box Filter
The Truckee Meadows projects: 
1. Urban Tree Box Filters placed along Virginia Street in downtown Reno allow gutter flow to enter landscape areas before flowing into the storm drain and river, receiving treatment by biological, chemical, and physical processes.
2. The McKinley LID Demonstration project is now complete, and showcases a local pervious concrete application. This project was designed in house, and utilized Design Guidance Worksheets for proper sizing to capture and treat a minimum of the 90th percentile storm (0.6").

Denver - structural controlThe picture shows a structural control located in Denver, CO, a sand filter extended detention basin. This structure passively treats storm water runoff from a  parking lot of about 10 acres and has had no problems in 10 years. Design was based on  criteria outlined in the Urban Storm Drainage Criteria Manual, Vol. 3 - BMPs (UDFCD, Denver CO, September 1999).
