Greater Phoenix Green Infrastructure Handbook: Low Impact Development (LID) Details for Alternative Stormwater Management

The Greater Phoenix Green Infrastructure Handbook: Low Impact Development (LID) Details for Alternative Stormwater Management (LID Handbook) is now available for public and private sector use!

The LID Handbook includes guidance and technical standard details and specifications for select LID techniques, so local design, planning, and development professionals can more easily integrate green infrastructure (GI) and LID in new and/or retrofit projects throughout Maricopa County. LID techniques included in the Handbook:

  • Biorention planters
  • Bioretention systems
  • Bioswales – vegetated or rock
  • Curb extensions
  • Curb openings
  • Domed overflow structures
  • Permeable pavements
  • Sediment traps
  • Stormwater harvesting basins

Image concept of low impact developmentFor almost two decades, Arizona has experienced drought conditions, raising concerns about water availability, use, and conservation. The use of GI and LID can provide many benefits onsite and to the surrounding communities and watershed, such as:

  • mitigating localized flooding
  • harvesting stormwater to offset potable water use for outdoor use
  • providing water to surrounding landscapes
  • reducing non-point source pollutant loads and erosion
  • increasing rainfall and runoff infiltration into soils
  • recharging groundwater
  • preserving and improving natural wildlife and habitat
  • beautifying surrounding streetscape
  • reducing heat-island effect
  • improving the health of the local watershed

The LID Handbook is a collaborative project of the SCN Green Infrastructure Specs & Standards Workgroup, created to benefit all communities in the Greater Phoenix Metro region. To make the Handbook a reality, the City of Scottsdale received grant funding from the Arizona Department of Environmental Quality (ADEQ) 604(b) grant program and the Water Infrastructure Finance Authority (WIFA) Technical Assistance Fund. The City also contributed funding and grant management to the project. With stakeholder and review support of eight Phoenix area municipalities, and the guidance of a core team comprised of the cities of Scottsdale and Phoenix, SCN and the Flood Control District of Maricopa County, the LID Handbook is now available for voluntary use throughout Maricopa County.
