City of Pleasanton—Hidden Canyon Residences and Preserve Project <br />CEQA Findings of Fact and Statement of Overriding Considerations <br /> <br /> <br />FirstCarbon Solutions 27 <br />Https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480016/FOF/21480016 Pleasanton Hidden Canyon Residences and Preserve Project FOF.docx <br />Minimization <br />To minimize impacts, measures taken during construction activities shall include <br />placing construction silt fencing around preserved aquatic features and riparian <br />areas to ensure that construction activities do not inadvertently impact these areas. <br />As part of project buildout, all proposed lighting shall be designed to avoid light and <br />glare impacts to preserved riparian corridors. Light sources shall not be visible from <br />riparian areas and will not illuminate riparian areas or cause glare on the opposite <br />side of the channels (e.g., to neighboring properties). Additionally, proposed <br />development activities shall be designed and situated to avoid loss of trees within <br />any riparian areas to the maximum extent practicable. Project construction must <br />setback from the Tree Protection Zone (TPZ) of trees within the riparian area. A TPZ <br />is defined as a circle whose center is within the base of an oak tree, the radius of <br />which is equal to an oak tree's height or 10 feet, whichever is greater. <br />Compensation <br />A wetland/riparian Mitigation and Monitoring Plan (MMP) shall be prepared to <br />compensate for a loss of approximately 0.25 acre of seasonal wetlands, 0.06 acre of <br />a Roadside Drainage Ditch, and up to 0.06 acre of the loss of riparian habitat (see <br />Table 3 of Appendix C1). The plan shall identify on-site preservation areas having a <br />sufficient water budget (as determined by a Hydrologist) for the creation of seasonal <br />wetland habitat that is of equal or greater quality to the seasonal wetland habitats <br />being impacted at a minimum 2:1 creation: loss. If sufficient areas for the creation of <br />wetland habitat cannot be identified on the preserve area, then the MMP shall <br />include off-site mitigation, preferably within the same watershed, as an alternative <br />strategy. At a minimum, the MMP shall: <br />xx Define the location of all created wetlands. <br />x Provide evidence of a suitable water budget to support any created wetland <br />habitats, as determined by a qualified Hydrologist. <br />x Identify species, size, number, and location of plants to be installed. <br />x Identify time of year for planting and any methods for supplemental watering <br />during the establishment period. <br />x Identify the monitoring period for wetlands of no less than 5 years and no less <br />than 10 years for riparian creation/enhancement. <br />x Identify measures that will be monitored, and define incremental and final <br />success criteria that will be required for the wetland mitigation to be deemed a <br />success. <br />x Identify adaptive management procedures that accommodate uncertainty that <br />comes with wetland creation projects. These include (but are not limited to) <br />measures to address colonization by invasive species, unexpected lack of water, <br />excessive foraging of installed wetland plants by wildlife, etc. <br />x Define management and maintenance activities (weeding, repair of water delivery <br />systems and browsing protection, etc.).
