Permanent stormwater pollution measures or PSPPM

The design and implementation of the PSPPM must be in accordance with the guidelines and technical specification approved by the Town or other Town-approved authority and the requirements of Order No. 01-119.
Site design measures
mean any project design feature that reduce stormwater pollution by decreasing or slowing stormwater runoff or intercepting the flow of runoff across a series of contiguous impervious surfaces.
