[Adopted 12-18-2007 by Ord. No. 28-2007]
This article shall be known as the "Adams County Stormwater
Runoff Ordinance," hereinafter referred to as "this article."
The Adams County Board of Supervisors finds that unfiltered
stormwater runoff and erosion from land disturbing activities can
have significant adverse impacts on local surface and ground water
resources and on the health, safety, and general welfare of the community
and diminishes the public enjoyment and use of natural resources within
Adams County. Specifically, unfiltered post-construction stormwater
runoff and erosion from land disturbing activities can:
A. Degrade lakes and streams by increasing bank erosion and negatively
altering groundwater recharge and base flow rates.
B. Diminish the capacity of lakes, streams, and wetlands to support
fish, invertebrates, aquatic vegetation, and water supply by increasing
pollutants, suspended solids, and heavy metals.
C. Threaten public health, safety, property and general welfare by increasing
flood peaks and flood volumes and overtaxing drainageways.
D. Diminish water quality due to sediment and nutrient delivery.
The Adams County Land and Water Conservation Department, under
direction of the Adams County Planning and Zoning Committee, is designated
to administer and enforce this article.
This article applies to towns and unincorporated areas within
the jurisdictional boundaries of Adams County.
As used in this article, the following terms shall have the

All stormwater runoff is confined within property boundaries
during and post construction.
C.
Site is not in violation of ordinance.
LAND DISTURBING ACTIVITY
Any of the following:
A.
Structural development, including construction of a new building,
parking lot, or other such structures;
B.
Expansion or alternation of an existing structure that results
in an increase in the surface dimensions of the building, parking
lot or other such structures;
C.
Creation or expansion of impervious surface; or
D.
Will ultimately result in the creation or maintenance of a subdivision,
condominium, industrial or commercial development.
LWCD
