REV: 09-14-2022 EI providing adequate notice and coordination to ensure availability of the biological services firm to perform a pre-construction bat survey within 30 days of starting on-site work, to layout the work area, and to perform education training and site monitoring during all on-site maintenance cleaning activities. Protection of Channel: Pursuant to the SAA, the following measures shall be taken to protect the Channel: A. A clamshell bucket and hand tools shall be used to remove vegetation from the Channel. B. No equipment shall be placed or operated in the Channel. C. Mowing shall only occur on top of bank above ordinary high water level and shall not occur within the Channel or lower bank. D. Staging and storage areas for equipment, materials, fuels, lubricants and solvents shall be located away from the wetted areas. E. Any equipment or vehicles operated adjacent to the creek areas shall be checked and maintained daily to prevent leaks of materials into the water. Vehicles must be moved 150 feet away from the stream prior to refueling and lubrication. F. All workers shall decontaminate waders, boots and other clothing that will come in direct contact with the water to prevent the spread of aquatic diseases. The decontamination of clothing and equipment shall comply with the methods included in the SAA - Avoidance and Minimization Measures Item 2.6 (Exhibit A-1). These methods are summarized below, and one or more of these methods shall be used: a. All equipment shall be dried in an upland location following last aquatic use. The minimum drying time depends on the average daytime temperatures, at least 7 days of drying time for average daytime temperatures more than 80 °F and at least 30 days of drying time for average daytime temperatures less than 80 °F. b. Scalding water wash (at least 140 °F) with varying high and low pressure spray to dislodge pathogens and vegetation. c. Freezing at a temperature less than 32 °F for more than 72 hours. d. Soaking in a hospital-grade disinfectant solution for at least two minutes. Disinfected clothing and equipment shall be thoroughly rinsed in a water bath before entering the stream. Repeat decontamination is required only if the equipment/clothing is removed from the site, used within a different waterbody, and returned to the project site. Site Considerations Staging and access for the project will be from the public right-of-way on Marsh Road and Haven Avenue, adjacent to the Channel. No equipment, with the exception of hand tools and clamshell bucket, shall be allowed within the Channel. Due to site constraints, traffic control will be required. The City of Menlo Park shall provide traffic control devices (e.g. cones, barricades, warning signs, etc.) and other incidentals to control automobile traffic safety around the sites. The City of Menlo Park shall close the sidewalk next to the Channel and re-direct pedestrian traffic while work is in progress. Redwood City shall handle worksite safety and work equipment traffic control if it is required, which shall comply with all City of Menlo Park standards. Construction operations shall be conducted in such a manner to cause as little inconvenience to vehicle and pedestrian traffic as possible. Redwood City shall follow all City of Menlo Park NPDES requirements and Best Management Practices (e.g. straw or fiber rolls, storm drain filters) to keep miscellaneous litter and trash out of ATTY/AGR.2022.328/City of Redwood City (Page 10 of 40) DocuSign Envelope ID: B10E2B21-03D4-4644-8E80-12E9BDEF8B3F
