Yes

A brief description of other technologies or strategies for stormwater management employed:

Catch basins, roofs, & parking lots are inspected and cleaned for the removal of excess dirt, sand, and debris.

The riding mowers use biodiesel.
The security trucks and mini trucks used for grounds keeping are both electric.
