jurisdiction, then the builder is responsible for verifying the
applicable tree protection standards and for installation of tree
protection measures as required by the municipality.
Install silt fence on low elevation sides of each lot and install silt
fence outlets shown on schematic/diagram and as needed.
Install required silt fence within 10 feet of property lines to
ensure there is no conflict with septic system. It is the
responsibility of the builder to ensure septic system is not
impacted by silt fence installation.
It is the responsibility of the builder to ensure installation of
erosion control measures does not impact septic system and

Check dams are used in channels to reduce erosion in drainage
ditches.
Height and width of the check dams are determined by existing
topography and sediment storage requirement.
Set spacing between check dams so that the elevation at the top
of the lower dam is the same as the toe elevation of the upper
dam.
Wattles may be used in lieu of check dams if they are installed
and maintained as per manufacture's specification. Wattle
diameter should be specified based on channel cross section.
Inspect check dams at least once a week and after each rain
event. Complete any required repairs immediately. Remove
sediment accumulation from behind check dams to prevent
damage to the channel vegetation. Flow should be maintained
through the dam.
