Lombardo Manager University Sustainability Practices |
Does the institution use Low Impact Development (LID) practices as a matter of policy or standard practice to reduce rainwater/stormwater runoff volume and improve outgoing water quality for new construction, major renovation, and other projects?:
A brief description of the institution’s Low Impact Development (LID) practices:
Arizona State University seeks to alleviate the impact of runoff and address runoff at the source. ASU is utilizing the national program Sustainable Sites Initiative (SSI) as a guideline for the College Avenue Streetscape project. This program was created to promote sustainable land development and management practices. ASU would like to use this guideline on more projects across campus so that water can be managed in a way that reduces the impact of built areas. The University has established LEED standards and won awards for excellence on new construction projects. For additional information about LEED certified buildings on ASU campuses: http://cfo.asu.edu/fdm-recently-completed-construction.
Has the institution adopted a rainwater/stormwater management policy, plan, or strategies that mitigate the rainwater runoff impacts of ongoing campus operations through the use of green infrastructure? :
A brief description of the institution’s rainwater/stormwater management policy, plan, and/or strategies for ongoing campus operations:
Part of the design phase of construction projects on ASU campuses includes retaining civil engineers to prepare site plans that retains stormwater within the property lines and ensures that surface drainage is designed so that stormwater is conveyed to adequate retention and detention structures. ASU Tempe campus has many retention basins equipped with drywells and underground retention tanks to retain stormwater on our campuses and reduce stormwater runoff. In addition, ASU has a drywell and stormwater drainage maintenance program. ASU’s Polytechnic campus has preserved natural landscape features such as such as desert drainage washes, arroyos and bioswales. ASU’s Downtown campus also has bioswales to capture rainwater to slow it down so that it infiltrates into the ground.
A brief description of any rainwater harvesting employed by the institution:
Rainwater harvested directly and stored/used by the institution, performance year:
A brief description of any rainwater filtering systems employed by the institution to treat water prior to release:
A brief description of any living or vegetated roofs on campus:
A brief description of any porous (i.e. permeable) paving employed by the institution:
Porous paving has been discussed as a choice of material for several projects on campus. At this time, the parking lot west of the Fine Arts Center and several pedestrian walkways across campus have porous paving to infiltrate water into the subsurface.
A brief description of any downspout disconnection employed by the institution:
Many downspouts that collect rain water from roofs are directed so that they empty into landscape and retention basins.
A brief description of any rain gardens on campus:
A brief description of any stormwater retention and/or detention ponds employed by the institution:
The Tempe campus has many retention basins equipped with drywells and underground retention tanks to retain stormwater on our campuses and reduce stormwater runoff.
The Polytechnic campus, enhanced natural desert drainage washes have been added to reduce stormwater runoff in the heart of campus and at the Vermont Road improvement project area. At the West campus there is a retention basin at the southeast area. When the city park area was constructed, the size of the drainage area was increased for future growth. All drainage at the West campus goes to these areas.
A brief description of any bioswales on campus (vegetated, compost or stone):
The University incorporates vegetated swales all across campus to hold stormwater before going to retention basin and drywells.
A brief description of any other rainwater management technologies or strategies employed by the institution:
The University has constructed underground retention tanks, additional drywells and retention basins to reduce stormwater runoff throughout all Arizona State University campuses.
