9. INTERIM, PERMANENT STABILIZATION and LONG TERM STORMWATER MANAGEMENT
The Contractor shall comply with all interim stabilization and permanent stabilization requirements in accordance with subsection
208.04(e).
A.SEEDING PLAN
Seeding will be required for an estimated 0.94 acres of disturbed area within the project limits which are not surfaced. The
following seeding mixture is based on Garfield County Specifications. The Contractor shall verify with the County that this seeding
mix is appropriate for project. The following types and rates shall be used:
B.SEEDING APPLICATION: Drill seed 0.25 inch to 0.5 inch into the soil. In small areas not accessible to a drill, hand broadcast or
hydroseed at double the rate and rake 0.25 inch to 0.5 inch into the soil per subsection 212. Soil compaction shall be
minimized for areas where permanent stabilization will be achieved through vegetative cover.
C.MULCHING APPLICATION: Apply a minimum of 2 tons of certified weed free native hay or 2 1/2 tons of certified weed free
straw per acre and in accordance with Section 213, and mechanically crimp it into the soil in combination with an organic
mulch tackifier.
1.Prior to winter shutdown or the summer seeding window closure: Uncompleted slopes shall be mulched with 2 tons of
mulching (weed free) per acre, mechanically crimped into the topsoil in combination with an organic mulch tackifier per
subsections 208 and 213.
D.SPECIAL REQUIREMENTS:
1.Due to high failure rates, hydroseeding will not be allowed for permanent stabilization.
E.SOIL CONDITIONING AND FERTILIZER REQUIREMENTS: Minimum requirements for all disturbances to receive seeding (native).
*Biological nutrient shall not exceed 8-8-8 (N-P-K).
Humate shall be in accordance to 212.02. Humate and compost shall also be approved by Garfield County.
F.SOIL RETENTION COVERING: On slopes and ditches requiring a blanket or turf reinforcement mat (trm), the blanket/trm shall be
placed in lieu of mulch and mulch tackifier and placed after seeding (native). See Erosion Control Plan for blanket/trm
locations.
G.RESEEDING OPERATIONS/CORRECTIVE STABILIZATION
Prior to partial acceptance.
1.Seeded areas shall be reviewed during the 7 day inspections by the SWMP Administrator for Construction and or
Erosion Control Inspector for bare soils caused by surface or wind erosion. Bare areas caused by surface or gully erosion,
blown away mulch, etc. shall be re-graded, seeded, and have the designated mulching applied as necessary, at no
additional cost to the project.
2.The Contractor shall maintain seeding/mulch/tackifier/blanket/TRM, mow to control weeds or apply herbicide to
control weeds in the seeded areas until Partial Acceptance of the stormwater construction work.
10. PRIOR TO PROJECT FINAL ACCEPTANCE
A.Partial Acceptance shall be in accordance with subsection 107.25 (d), 208.10 and 214.04. At the Partial Acceptance of the
project, it shall be determined by the SWMP Administrator for Construction and the Engineer which temporary control
measures shall remain until 70% revegetation is established or which shall be removed.
B.At the end of the project, all ditch checks shall either consist of temporary erosion logs (or equivalent) or permanent rip-rap.
C.All storm drains shall be cleaned prior to the Final Acceptance of the project. Work shall be included in 202 Clean Culvert.
11. NARRATIVES
Control Measure Matrixes During Construction:
1.Control measure narratives have been included for the CDOT Standard Specifications and Standard Plan M-208 and M-216
along with any non-standard control measures approved during the design process. If a Non-Standard Control Measure not
included in the SWMP is proposed and approved by the Engineer the SWMP Administrator for Construction shall do the
following: Place an “X” in the column for non-standard and complete a Non-Standard Control Measure Specification and
Narrative covering the what, when, where and why the control measure is being used shall be add to the SWMP. The
appropriate “X” shall also be added to the implementation phase(s).
2.The SWMP Administrator for Construction shall place an “X” in the column In Use On Site when the control measure has
been installed.
3.A “P” in the Initial Activities Column indicates that the control measure shall be installed before construction activity
starts. Locations and quantities will be discussed during the Environmental Pre-construction Conference with the Regional
Water Pollution Control Manager.

NON-STRUCTURAL Control Measures that may be potentially used on the project for erosion and sediment control; practices may include, but are not limited to:
Erosion control devices are used to limit the amount of soil loss on site. Sediment control devices are designed to capture sediment on the project site. Construction controls are control measures related to construction access and staging.
Control Measure locations are indicated on the SWMP Site Map
* Use of vegetative buffer strip requirements. The CDPHE Water Quality Control Division Technical Memorandum dated August 27, 2015 clarifies the requirements for utilization of existing vegetation as a buffer type of sediment control
measure, while maintaining compliance with the CDPS permit for Stormwater Discharges Associated with Construction Activity - CDPS Permit No. COR4000000. In general, the division does not recommend that vegetated buffers be
implemented as a sediment removal control measure for runoff from disturbed areas at construction sites, unless implemented as a “finishing” component of a treatment train comprised of additional, adequate up-gradient Control
Measures. The entire memorandum can be found at: https://www.colorado.gov/pacific/sites/default/files/Vegetative%20Buffer%20Memo.pdf
