GENERAL NOTES:
1. The erosion control measures are shown schematically on the plan sheets. The Contractor is
responsible for placing the erosion control measures as required to protect the site from erosion
and transportation of sediment from the site. The Owner's representative and the Engineer may
require more or less erosion control measures.
2. Erosion control measures shall be placed before construction begins and/or placed immediately
after disturbance. Construction activities shall be phased to minimize soil exposure. Sediment
trapping practices shall be installed and stabilized before site grading or other construction is
initiated.
3. All disturbed areas and soil stockpiles shall be surface roughened, mulched, or seeded and
mulched to protect from erosive forces if they will remain exposed and inactive for periods longer
than fourteen (14) days, or if soil will be exposed during winter, so erosion will not occur during
spring snow melt. Disturbed areas shall be mulched, or seeded and mulched within seven (7)
days after final grade is reached.
4. Any disturbed area that is not built upon for one (1) year or longer shall be revegetated with
Co-op "Mountain Mix" native grass seed hand broadcast at a rate of 30 pounds/acre, raked in
and mulched with certified weed free straw mulch. Within one growing season of project
completion, vegetative site coverage shall be equal to or greater than seventy (70) percent of the
disturbed areas.
5. Place soil retention blankets on all disturbed slopes steeper than 4: 1 (h: v).
6. The contractor shall inspect all erosion and sediment control devices after any precipitation
event during construction, and make any necessary repairs immediately thereafter. At a minimum,
erosion and sediment control devices shall be inspected monthly. An inspection log shall be kept
on-site for review by Officials until the project is complete.
7. Dust control during construction shall be provided by the use of watering. Disturbed areas and
stockpiles shall be sprayed with water as necessary to control dust.
8. Straw or hay bales will be placed at any stormwater runoff points of concentration as
necessary to prevent erosion and sedimentation from disturbed areas. \ \\ ▪ \
9. Silt fence shall be installed along the edge of areas disturbed by construction and around / \
stockpiles. Silt fence shall be staked every six feet and buried six inches at the bottom of the
fence. / 10. Topsoil Topsoil shall be spread on all disturbed areas and revegetated per the landscape plan. If the \\ ;/
landscape plan does not specify vegetation in area disturbed, area shall be seeded with Co-op
"Mountain Mix" native grass seed hand broadcast at a rate of 30 pounds/acre, raked in and
mulched with certified weed free straw mulch. The seed may be drill seeded as an alternative to \ \
hand broadcast, raked and mulched. Grass or straw mulch shall be crimped in place. \ \ \ \ \
11. The project will disturb more than one acres and therefore will require a permit from CDPHE. \ \\\\ \
Sediment and erosion control is required in Garfield County. \. " • ,\
12. Area of site expected to undergo disturbance is approximately 2.0± acres. \ \ \ \ \ \ \
13. Estimated runoff coefficients of the site before construction activities: 89.7 Estimated runoff \ \ \ \ \
coefficients of the site after construction activities: 94.5. Existing soils are Atencio-Azeltine \\ \ \ \ \ \ \ \
complex, 1 % to 12% Slopes. \ \ \\ \ i
\14. Existing vegetation is mainly grass with locations of sage, scrub oak, and aspen. Estimated \\\ \\\ vegetative cover is "good" with between 70% vegetative ground cover.\\\\\ \ \ \15. Ultimate receiving water is the Roaring Fork River approximately 250 feet away through a\\ \\ �\ \ \series of ditches and culverts.\\\ \\\ \16. Silt fencing of site, construction access, and straw bale check dams to be installed prior to\`\ \ \\\ \\ \
clearing and excavation activities. Temporary measures of inlet protection, swale check dams, and \\ \\\ \\\\ \\ \
silt fence around fill slopes and stockpiles to be installed immediately after items have been \\\\ \ \�\\ \\ \ \ \\ \
installed. Temporary measures to be removed just prior to the installation of permanent \ \\ \\ \ \\ \ \ \
measures such as revegatation, seeding, rip rap, and soil retention blankets. \ `\\� \\\\ \\\ \\
17. Construction activities can be expected to increase the potential for storm runoff to erode the \\ \\\ \ \ \ \ \\ \
site. Temporary structures have been designed to contain sediment on the site and to mitigate \ \ \\\ \\ `\ \ \\ \� \ \ \
erosion from construction activities. Straw bale check dams are placed in drainage swales and \

A mat of biodegradable material placed on all disturbed slopes
steeper than 4:1 (H: v) to retain site soils, topsoil, and seeds. The
matting provides a temporary vegetative mesh until plants mature.
The installation of various kinds of sediment trapping measure around
inlets, culverts and structures prior to permanent stabilization of the
disturbed area; limited to small drainage areas and not intended to
control large, concentrated stormwater flows.
A permanent channel or flow direction constructed across a slope to
intercept, direct, and/or divert stormwater runoff to a stabilized outlet
to prevent erosion on the slope.
A basin with a controlled stormwater release structure, formed by
constructing an embankment of compacted soil across a drainageway,
to detain sediment -laden runoff from disturbed areas greater than 5
acres for enough time to allow most of the sediment to settle out.
Can be constructed only where there is sufficient space and appropriate
topography. Temporary unless designed as a permanent pond.
A gravel pad, located at the points of vehicular ingress and egress
on a construction site, to reduce the mud transported onto roads
and paved areas.
A temporary sediment barrier composed of anchored straw bales
places across or at the toe of a slope to intercept and detain
sediment and decrease flow velocities from small drainage areas;
applicable where sheet and rill erosion potential is low.
A temporary sediment barrier constructed of posts, filter fabric and, in
some cases, a wire support fence, placed across or near the toe of a
slope or in a minor drainageway to intercept and detain sediment and
decrease flow velocities from rainage areas of limited size; applicable
where sheet and rill or small concentrated flows may be a problem.
Silt -Sox or approved equal are acceptable.
Reducing surface and air movement of dust during land disturbance,
demolition or construction activities in areas subject to dust
problems in order to prevent soil loss and reduce the presence of
potentially harmful airborne substances. Includes the covering of soil
stock piles and construction materials and wetting site soils.
