Urban Subwatershed Restoration Manual 11: Unified Subwatershed and Site Reconnaissance: A User’s Manual

Unified Subwatershed and Site Reconnaissance: A User’s Manual (February 2005) is Manual 11 in the Urban Subwatershed Restoration Manual (USRM) Series. Developed by the Center for Watershed Protection, the manual examines pollution sources and
restoration potential within upland areas of
urban subwatersheds. The manual provides
detailed guidance on how to perform each of its
four components: the Neighborhood Source
Assessment (NSA), Hotspot Site Investigation
(HSI), Pervious Area Assessment (PAA) and the
analysis of Streets and Storm Drains (SSD).
Together, these rapid surveys help identify
upland restoration projects and source control to
consider when devising subwatershed
restoration plans.
