The Green Build-out Model is a planning tool that quantifies the cumulative stormwater management benefits of trees and green roofs for different coverage assumptions across the District of Columbia. It calculates potential reductions in stormwater runoff within the municipal separate storm sewer system (MS4) and the combined sewer system (CSS) that contribute to water quality impairment in the Nation’s capital.
Provides guidelines for using low impact development techniques to manage stormwater. Includes information on the local approval process for a project design criteria for various low impact development practices.
This is more than a fact sheet. Included with a description of the BMP, is information on maintenance, costs, design details, benefits, case studies and references.
Soak Up the Rain (SOAK) New Hampshire is a voluntary program managed by the New Hampshire Department of Environmental Services. The goal is to protect and restore clean water in the state’s lakes, streams, and coastal waters from the negative impacts of stormwater pollution. SOAK provides information about how our homes create stormwater pollution and how to prevent it with rain gardens, infiltration trenches, and other practices.
Seattle’s Urban Forest Management Plan provides a long term vision for increasing tree canopy cover (the percent of the city covered by trees as seen in an aerial view) and the myriad environmental, social, and economic benefits associated with trees in urban areas.
Pittsburgh’s Urban Forest Master Plan is often looked to as a “gold standard” for urban forestry planning. The Master Plan is a road map, providing detailed information, recommendations, and resources needed to effectively and proactively manage and grow a city’s tree canopy. More importantly it provides a shared vision for the future of the urban forest to inspire and engage stakeholders in the care and protection of trees.
A low impact development approach is when stormwater is managed on-site and the rate and volume of predevelopment stormwater reaching receiving waters is unchanged. On this website the low impact development approach is described: for citizens, policy, practices, case studies, funding availability, brownfield sites, and design standards.
New Orleans has codified tree planting and mature tree protection in their landscape and stormwater ordinance
It is critical for local governmental entities to adopt sound, comprehensive stormwater management ordinances that incorporate best practices. IDNR/OWR and the Illinois State Water Survey (ISWS) developed a Model Stormwater Management Ordinance as a resource for counties and municipalities to use when drafting or revising their own stormwater ordinances. While local development, review, and approval processes are unique, IDNR/OWR provides this document as a template containing the minimum requirements for an effective ordinance and suggestions for more advanced stormwater protection. It particularly addresses tree protection and GI maintenance.
This Stormwater Management Model Ordinance was developed by the Virginia Department of Conservation and Recreation Department for use by a locality for establishing a Virginia Stormwater Management Program consistent with the Virginia Stormwater Management Act. While specific to Virginia, this document can provide guidance and information for localities developing stormwater management programs.
