SCOPE OF SERVICES Task 1. Extra Service Provided During Construction and Year 1 Mitigation Monitoring and Reporting Mosaic Associates provided the following out -of -scope services at the request of City of Pleasanton staff: 1. In 2008 we performed out -of -scope services, including biological survey and agency coordination re potholing (March 2008), agency correspondence re expansion of work area for temporary stockpiling of soils (July 2008), revisions to the Mission Creek planting plan (Oct 2008), team coordination and revisions to Arroyo del Valle plan due to reduced area of construction disturbance (Nov Dec 2008). 2. Additional out of scope service was provided in 2009 and in Jan 2010, including team coordination and multiple site visits to confirm status of mitigation sites, and describe outstanding work items for the contractor. We also prepared the wetland tracker form for the RWQCB which was billed to the contract, although we had not budgeted for it. We charged service to Year 1 that should have been charged to team coordination. 3. We paid for soils tests ($720) during construction that hadn't been included in the budget. It was more efficient for us to do that rather than put it on the contractor because we were then able to address soil amendments in the bid package. Out -of -scope services provided totaled $3687.04. Task 2. Year 2 Mitigation Monitoring and Reporting (2010) Mitigation monitoring will be conducted consistent with the Bernal Bridge On -site Wetland and Riparian Mitigation and Monitoring Plan (Bernal MMP, Mosaic Associates February 2008) and the Mission Creek Wetland and Riparian Mitigation and Monitoring Plan (Mission Creek MMP, March 2008). Biological performance -based monitoring of the wetland and riparian mitigation sites will be conducted during not more than three site visits per year. We will notify the City and the landscape contractor of the need for maintenance activities to help ensure good site performance, but the landscape contractor or City staff will be responsible for active site management and maintenance, including routine site visits to operate and maintain the irrigation system and implement weed control and other cultural requirements. We will collect data on plant survival, height and vigor, and cover at both sites, and hydrologic data at the Mission Creek site. We will make qualitative assessments of site performance, and will communicate findings in mitigation monitoring memos following site visits. Balance Hydrologics will continue to carry out the hydrologic monitoring plan described in the Mission Creek MMP. Balance will conduct field visits every 6 weeks to download water level and conductivity data from continuous recording dataloggers in the mitigation wetland and in the Mission Creek diversion structure, and to conduct manual measurements of water level, water temperature, inflow from Mission Creek, and specific conductance. Monitoring will be conducted on a water year basis (October 1 through September 30). City of Pleasanton/proposal years 2 -5(3) 4
