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:

Stormwater runoff is an important factor in water conservation in our region. The more water that can be retained on site, the less artificial irrigation is needed. The City of Flagstaff created an extensive Low Impact Development Plan that the university has adopted for all new construction projects.The City of Flagstaff Low Impact Development Plan is also used to control stromwater runoff across campus by keeping the first inch of rainfall on site.

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:

A brief description of any rainwater harvesting employed by the institution:

Small scale harvesting occurs at student gardens.

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:

The ARD "pod" conference room has a vegetative roof to model both how soil can act as an insulator and how we can combat the heat island effect. In addition, the roof absorbs rainfall helping to improve stormwater runoff of this building.

A brief description of any porous (i.e. permeable) paving employed by the institution:

A brief description of any downspout disconnection employed by the institution:

A brief description of any rain gardens on campus:

A brief description of any stormwater retention and/or detention ponds employed by the institution:

NAU uses retention ponds to meet LID requirements.

Also outside the ARD Buidling, landscaping is designed to collect and filter pollutants in the detention basin as well as help control flooding.

A brief description of any bioswales on campus (vegetated, compost or stone):

This is the primary method of stormwater collection on campus.

A brief description of any other rainwater management technologies or strategies employed by the institution:
