Stormwater Management
Effective July 1, 2014, Henrico County will administer a Virginia Stormwater Management Program (VSMP) as required by the Virginia Stormwater Management Act (§ 62.1-44.15:24 et seq. of the Code of Virginia. The requirements of the program, as well as the other environmental programs implemented in the County, have been described in the Henrico County Environmental Compliance Manual. This manual replaces the Henrico County Environmental Program Manual dated August 2001.
Two Stormwater Pollution Prevention Plan (SWPPP) templates for use in Henrico are also available – one for construction on single-family residential lots and another for other construction activities such as subdivisions and plans of development.
In addition to the new manual and the SWPPP templates, many administrative forms were also developed or revised as a result of the program:
- Declaration of Covenants for Inspection and Maintenance of Stormwater Management Facilities for proprietary/manufactured devices
- Declaration of Covenants for Inspection and Maintenance of Stormwater Management Facilities for facilities with safety concerns and access related concerns such as vegetated roofs, wet ponds, permeable pavement, and facilities with underground/enclosed chambers
- Declaration of Covenants for Inspection and Maintenance of Stormwater Management Facilities for other facilities
- Environmental Compliance Agreement for use of the Environmental Compliance Bond (replaces the previous Erosion and Sediment Control Agreement)
- Letter of Credit Form (replaces the previous Letter of Credit form)
- Assignment for Environmental Compliance Measures (replaces the previous Assignment for Erosion and Sediment Control Measures)
- Agreement in Lieu of a Stormwater Management Plan
- Agreement in Lieu of an Erosion and Sediment Control Plan
The County also conducted several workshops to prepare contractors, consultants, and homebuilders for implementation of the program. The information presented during these workshops is available for Contractors, Engineers and Home Builders.
Several of the following standard plan sheets were also revised to incorporate some of the new program requirements.

A new Pollution Prevention Plan sheet has also been developed that must be included in plans for projects requiring coverage under the General Construction Permit.
The following checklists will be used by County staff to review for compliance with the requirements of the applicable requirements. Please note the plan review checklists have been revised to incorporate the new technical and administrative requirements of the VSMP.
In addition, review checklists have been developed for each SWM facility type described in the Henrico County Environmental Compliance Manual. The applicable checklist will be used to review each SWM facility proposed on a project.

Environmental Compliance Plan
Soil erosion is the process of detachment and transportation of soil materials by water, wind, ice and gravity. Henrico County’s Environmental Compliance Plan deals with erosion resulting from (water) raindrop impact on un-stabilized soil, primarily during the development process…more
Virginia Pollutant Discharge Elimination System Program
The National Pollutant Discharge Elimination System (NPDES) is an EPA permit program which took effect in 1972 and is responsible for significant improvements in the quality of our nation’s waters. EPA delegated this permit authority to the State and in Virginia this permit is known as the VPDES permit. The County of Henrico has a VPDES permit which allows us to discharge our stormwater into state waters. This permit also has guidelines for improvements which the County implements on an ongoing basis like BMPs, stream restorations, stream cleanings, and many others…more
