Bacteria Source
Urban Areas
Domestic Pets
(dogs and cats)
Urban Wildlife
Potential BMP/Management Strategy
Signage to pick up dog waste, providing pet waste bags and garbage cans.
Enforcement of pet waste ordinances.
Use of dog parks away from environmentally sensitive areas.
Reduce food waste sources from commercial waste/grease spillage entering the
storm drain.
Illicit Connections to
Storm Sewers
Identification and removal of illicit sanitary and floor drain connections through
municipal stormwater dry weather survey programs.
Leaking Sanitary
Sewer Lines
"TVing" sanitary sewer lines to identify leaks or breaks that may cause seepage of
untreated sanitary wastewater to streams or storm sewers.
Illegal Dumping
Enforcement, by municipal stormwater programs, related to illegal dumping.
Runoff from Urban
Areas
Dry Weather Irrigation
Flows
Encouraging low impact development and development designs that minimize
directly connected impervious areas, allowing stormwater to seep into the ground
rather than run off into storm sewers. See Chapters 3 and 4.
Dry weather flows from storm sewers can be reduced through better-controlled
lawn/park irrigation practices.
Transient Populations
Open Space
Waterfowl
Canadian Geese
Wildlife: Beavers,
deer, raccoons,
coyotes, mice
Domestic Pets
Support of city shelters and services to reduce homelessness.
Population controls (e.g., egg oiling, addling, dog harassment). See
www.geesepeace.org for more information. Habitat modification is another
potential BMP.
Restoration of degraded riparian buffers.
Consult with Colorado Division of Wildlife (CDOW); consider controls to make
storm drains less desirable as animal homes; beaver trapping and relocation may be a
consideration.
Restoration of degraded riparian buffers.
See description above. In addition, strategic trail design incorporating vegetative
buffers and grading away from the stream.
Restoration of degraded riparian buffers.
