Which of the following best describes the institution’s approach to rainwater management?:
Comprehensive policies, plans or guidelines that require LID practices for all new projects

A brief description of the institution’s green infrastructure and LID practices:

From ASU’s Sustainable Design Guidelines, applicable to all new construction and major renovations:
“Provide a site location for collection opportunities for current and/or future water capture and reuse. Provide opportunities for rainwater harvesting and condensate collection.”
“Maximize the use of captured water (reclaimed, harvested rainwater, etc.) for landscape irrigation. Use irrigation cisterns for water features in lieu of continuous potable water fountains.”
“Protect significant natural and historic landscaping and incorporate those elements into the new landscape design.”
“Utilize permeable surfaces to reduce runoff and reflective surfaces to reduce the urban heat island effect.”
“Program the site to create a “sense of place” through the design of a variety of experiences and activities with micro-climates appropriate to desert climate conditions. Maximize opportunities to create landscape shading and cooling for the building, exterior spaces, and walkways while also specifying low maintenance and desert-appropriate plant materials.”

A brief description of the institution’s rainwater management policy, plan, and/or guidelines that supports the responses above:

Arizona State University’s green infrastructure and LID practices are guided through:
(1) ASU’s requirement that all new construction and major renovations at ASU will be built to LEED Silver standards or higher. Several parts of LEED include green infrastructure and LID practices.
(2) ASU’s Sustainable Design Guidelines, applicable to all new construction and major renovations
(3) ASU’s use of the USGBC Sustainable SITES® landscape rating system. The SITES system includes a prerequisite that requires that the projects manage precipitation on-site so as to “reduce negative impacts to aquatic ecosystems, channel morphology, and dry weather base flow by replicating natural hydrologic conditions and retaining precipitation on site.”
