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.

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.

OTHER 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.
