1 Sequoia Ecological Consulting,Inc. Page Final Scope of Work for Environmental Regulatory Compliance& 11 of 14 Habitat Mitigation Services for Stream Maintenance Project October 2022 TASK 5. HABITAT MITIGATION: MONITORING AND REPORTING Sequoia will complete monitoring and reporting of the Mitigation Area annually for six-years post- planting, this includes: establishing permanent photo-documentation points per WQC (initial establishment covered under Task 3), annual data collection which includes quadrat sampling methodology as described in the HMMP, power analysis in initial planting year to evaluate quadrant sampling size, and monitoring and determination of success criteria. Based on the current schedule, 2023 will be the installation year and accordingly monitoring will begin in 2024 (Year 1) and extend through 2029 (Year 6). If success criteria are not met by Year 6 and additional monitoring is required, Sequoia may perform this work at the request of the City with a Change Order.To accomplish this, we propose to implement the following tasks: 5.1 Project Management/Coordination and Planning Prior to the first annual monitoring event,Sequoia's Project Manager and QB will thoroughly review the HMMP, agency permits, as-built plan, and available baseline records to establish a monitoring protocol, monitoring plan checklist, data sheet templates, sampling locations, and field maps. 5.2 Annual Monitoring Visits Sequoia will conduct post-construction mitigation monitoring once annually for a 6-year monitoring period (assuming Year 1 is 2024) after planting for species in riparian understory and upland transition zones, pursuant to the HMMP.Sampling and data collection within the Riparian Enhancement Planting, Invasive Species Management, and Mowing Reference Areas will occur concurrently during one field event to save on mobilization and travel costs.A team of qualified restoration ecologists and botanists, one of whom is a certified consulting botanist,will follow the methodology described in the HMMP to collect data, including planting counts, survivorship,and health and vigor, percent canopy cover of riparian and invasive species using quadrats/transects,and planting height within the three Mitigation Areas. Surveys will be timed to coincide with peak vegetative and blooming phenology(i.e., before summer senescence of California buckeye, if present)to ensure accurate identification and assessment of survivorship, cover, and health, likely in late spring/early summer(March-May). 5.2 Annual Monitoring Reports Sequoia's QB will prepare annual mitigation monitoring reports discussing actual impact amounts, mitigation actions, monitoring methodology, condition of vegetation at recovering Project Sites, and results to be submitted to the RWQCB and CDFW by December 31 of each year for 6 years, or until success criteria are met.The reports will contain all information and data specified in the WQC and HMMP necessary to assess the progress of mitigation activities
