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:
The campus has established LEED credits for storm-water management, rate and quantity storm-water management treatment as campus-wide credits. These are enforced through building projects and storm-water management plans. The campus has been designed to collect 100% of the storm water for all building development. There are multiple bio-swells on campus that help filtrate and slow rainwater runoff. In addition, over 50% of the parking lots are gravel with stormwater filtration built into them to collect storm water, treat and filtrate before it enters the 2 campus retention ponds.

A copy of the institution’s rainwater management policy, plan, and/or guidelines:
A brief description of the institution’s rainwater management policy, plan, and/or guidelines that supports the responses above:
Our current mitigation and policy requires the campus to collect and store 100% of its storm water for the 1 and 2 year 24 hour design storms. In addition, the campus is developing a storm-water management plan required by the State Water Resource Board that contains plans, practices, and requirements for ongoing campus operations and maintenance of UC Merced campus storm-water systems.

Additional documentation to support the submission:
Data source(s) and notes about the submission:
The campus storm water quantity and quality report explains how the campus collects 100% of the rainwater run off that promotes infiltration and captures and treats the storm water runoff from 90% of the average annual rainfall using best management practices (BMPs). The intent is to prevent the erosion of natural stream beds by increased run-off velocities and volumes while allowing storm water to infiltrate the ground - helping to maintain the natural
aquifer recharge cycle.
