Which of the following best describes the institution’s approach to rainwater management?:
No written policies, plans or guidelines, but green infrastructure and LID practices are used
A brief description of the institution’s green infrastructure and LID practices:
Williams' does not have general Low Impact Development practices but instead makes a separate assessment of what makes sense for every project.
A project manager with extensive stormwater management experience serves as the stormwater advisor on every capital project.
As much infiltration as possible is installed into new projects. Every new project is also planned to have an improved rainwater management system than what was there previously. We have either rain gardens, rain harvesting, or infiltration chambers in all newly constructed projects.
A few examples of current LID practices in use are:
-Catch basins that remove 80% of total suspended solids (TSS) from storm drains. They are cleaned once every 2 years.
-36" diameter perforated pipes below the surface of Paresky Lawn, allowing water to slowly drain into surrounding earth rather than running off over impervious surfaces
-Stormwater drains are monitored to catch more serious, non-solid contaminants from flowing into the local water source

A brief description of the institution’s rainwater management policy, plan, and/or guidelines that supports the responses above:
All new projects involve an evaluation of stormwater management that must be concluded before the project starts. We have to make sure that post-development flows are equal or less than pre-development flows in both volume and velocity. The college uses a range of different retention and detention structures.
