Exhibit A <br />b. Scalding water wash (at least 140 °F) with varying high and low pressure spray to <br />dislodge pathogens and vegetation. <br />c. Freezing at a temperature less than 32 OF for more than 72 hours. <br />d. Soaking in a hospital -grade disinfectant solution for at least two minutes. <br />Disinfected clothing and equipment shall be thoroughly rinsed in a water bath <br />before entering the stream. <br />Repeat decontamination is required only if the equipment/clothing is removed from the <br />site, used within a different waterbody, and returned to the project site. <br />Site Considerations <br />Staging and access for the project will be from the public right of way on Marsh Road and <br />Haven Avenue, adjacent to the Channel. No equipment, with the exception of hand tools, shall <br />be allowed within the Channel. <br />Due to site constraints, traffic control will be required. The City of Menlo Park shall provide traffic <br />control devices (e.g., cones, barricades, warning signs, etc.) and other incidentals to control <br />automobile traffic safely around the sites. The City of Menlo Park shall close the sidewalk next to <br />the Channel and re- direct pedestrian traffic while work is in progress. The City of Redwood City <br />shall handle worksite safety and vehicle traffic control if it is required, which shall comply with all <br />City of Menlo Park standards. Construction operations shall be conducted in such a manner to <br />cause as little inconvenience to vehicle traffic as possible. <br />The City of Redwood City shall follow all City of Menlo Park NPDES requirements and Best <br />Management Practices (e.g., straw or fiber rolls, storm drain filters) to keep miscellaneous <br />litter and trash out of the Channel and storm drains. The Contractor shall keep the City of <br />Menlo Park right of way clean of debris. After removal of spoils, the Contractor shall leave the <br />area in as clean a condition as it was before the work. <br />The City of Redwood City shall provide access to toilet facilities for its workers. There are no <br />public facilities near the work site. <br />Schedule and Hours <br />To minimize the conflict between the maintenance cleaning activities and the nesting season <br />of raptors and migratory birds, the work period will be restricted to September 15 to October <br />31. This will also ensure that maximum Channel capacity is achieved prior to the wet weather <br />season. <br />The allowable working hours will be 6:00 AM to 6:00 PM on Saturdays and Sundays, except <br />where otherwise specified by Public Works. The work is estimated to take no more than five (5) <br />working days. <br />Page 8 of 34 <br />ATFY /AGR /2018.243/CITY OF MENLO PARK_ATHERTON CHANNEL GSA <br />
