Maricopa County Green Infrastructure Guidelines 2019 Edition

2019 Greater Phoenix Metro Green Infrastructure Handbook. The purpose of this Handbook is to provide members of the design, planning, and development communities in Maricopa County, Arizona with guidance and specific techniques for low impact
development (LID) that can be implemented on their projects. The Handbook is intended to address non-point source pollutant load reductions, conformance with first-flush requirements, and stormwater peak flow and volume reductions for water quality and flood hazard mitigation benefits within the Salt and Gila rivers, specifically, and the Middle Gila Watershed in general. Equally important in the Sonoran Desert is the opportunity to ameliorate water supply/demand concerns by increasing rainfall infiltration, recharging groundwater, and harvesting stormwater to offset potable water used for outdoor purposes.
