Notification #1600- 2013- 0356•R3 Streambed Alteration Agreement Page 13 of 23 Exhibit A -1 Modifications, repairs and improvements to erosion control BMPs shall be made as needed to protect water quality. At no time shall silt laden runoff be allowed to enter the stream or directed to where it may enter the stream. 2.34 Treat exposed areas. All exposed /disturbed areas and access points within the stream zone left barren of vegetation as a result of the project activities shall be restored by seeding with a blend of native erosion control propagules (seeds, cuttings and /or divisions) of locally - collected native plants. Local native grass species include meadow barley (Hordeum brachyantherum ssp, califomicum), blue wildrye (Elymus glaucus), California brome (Bromus carinatus), creeping wildrye (Elymus triticoides), California oatgrass (Danthonia californica) and California melic (Melica californica). Locally native wildflower and /or shrub seeds may also be included in the seed mix. Re- vegetation shall be completed as soon as possible after construction activities in those areas cease. Seeding placed after October 15 must be covered with broadcast straw, jute netting, or similar erosion control blanket. 2435 Erosion Control Methods. Other disturbed areas around the creek shall be revegetated with propagules (seeds, cuttings, divisions) of locally - collected native plants. If locally collected native plants are not available, sterile or short-lived revegetation plants shall be used (e.g. cereal barley, Regreen). Disturbed areas shall be protected with correctly installed erosion control measures (e.g. jute, certified weed free straw, coconut fiber, or coir logs). Materials containing monofilament or plastic or similar material containing netting shall not be used within the project area due to documented evidence of amphibians and reptiles becoming entangled or trapped in such material. 2.36 Prohibited Plant Species, Permittee shall not plant, seed, or otherwise introduce invasive plant species. Prohibited exotic plant species include those categorized as "High" and "Moderate" in the California Invasive Plant Council's Inventory Database, which is accessible at: http: / /www.cal- ipc,orq /paf /. 2.37 Staging and Storage Areas. Building materials and /or construction equipment shall not be stockpiled or stored where they could be washed into the water or where they will cover aquatic or riparian vegetation. 2.38 Equipment over Drip -pans. Staging and storage areas for equipment, materials, fuels, lubricants and solvents shall be located away from the wetted areas. Stationary equipment such as motors, Page 22 of 34 ATTY /AGR /2018.243/CITY OF MENLO PARK_ATHERTON CHANNEL GSA
