Watershed Restoration
Your community's revitalization should eventually encompass your
entire region for maximum effectiveness. But, it
can start with a primary focus on any of the
12 sectors of restorable assets, at any scale.
One of those restorable assets is your watershed.
If you've already got a strong
watershed restoration program, it can be an excellent
foundation from which to launch your
Renewal Capacity Program.
Definition &
overview: There are a number of definitions of
"watershed". Here is one from Webster's New
Collegiate Dictionary: "The whole region or area
contributing to the supply of a river or lake; drainage
area." The Federal Hydrologic Unit Code used
in the U.S. (especially in the U.S. Army Corps of
Engineers), divides water resource areas into the
following taxonomy, starting with the largest and
descending: region, subregion, basin (as in river
basin), subbasin, watershed, and subwatershed.
Integrated
water resources planning is the most powerful trend in
water industries today. Given the distressed,
overtaxed condition of most watersheds around the world,
and the decrepit, obsolete, and overtaxed condition of
most sewage and drinking water infrastructure in
communities around the world, it's no surprise that the
largest component of most integrated water resources
plans is restorative, as in
redesigning/replacing/renovating existing water
infrastructure, restoring watersheds, etc.
To illustrate
this integration trend, here's a quote from "River
Basins and Coastal Systems Planning within the U.S. Army
Corps of Engineers" (National Research
Council of the National Academies of Sciences, 2004): "An
ideal environment for fully integrated water project
planning that addresses social, economic, and
environmental objectives at all relevant spatial and
temporal scales would require a substantial amount of
advance investigation and planning at the scale of river
basins and coastal systems.... The Corps and other
federal agencies have been charged with fostering an
'ecosystem approach' that seeks to integrate social and
economic goals with the restoration and preservation of
natural ecosystems. Simply minimizing harm to the
environment is, therefore, no longer sufficient. The
Corps should endeavor to improve environmental quality
in all of its projects (not just its restoration
projects)."
