Bringhurst LLC at 990 Sycamore Road Initial Study and Negative Declaration PRA. Both the initial report in 2007 and the update in 2018 concluded that based on the results of the exploratory boring and laboratory testing, no indication of an active fault would be expected to cross the property. The reports concluded that the subject site can be developed with the proposed project subject to the design and construction recommendations stated in the reports. These reports were peered reviewed by Engeo, Inc., acting as the City's geotechnical peer review consultant. Engeo concurred with the conclusion and recommendations in the PRA reports4. In addition, Engeo indicated that the seismic design of the new homes would need to conform to the applicable building codes at the time of construction. Based on reports and peer review recommendations, the project would be designed to address earthquake safety issues and adherence to the requirements of the California Building Code; therefore, seismically-induced ground shaking would not be a substantial hazard on this site. Potentially unstable soils discovered during excavation are required by provisions of the California Building Code to be removed and replaced, or otherwise treated to provide appropriate foundation support. As a condition of approval, the project is required to comply with the recommendations of the project's geotechnical consultant, including designing foundation and drainage geotechnical aspects of the final development plans to ensure that the recommendations have been properly incorporated into the project. Therefore, the potential impact would be less than significant. b) Natural erosion is frequently accelerated by human activities such as site preparation for construction and alteration of topographic features. Grading, as well as excavation and trenching for utility lines, will disturb soils, which could increase the rate of erosion if controls or best management practices are not in place. As a standard condition of approval, the project is required to meet the requirements for stormwater erosion control measures during design, construction and implementation phases of the project. Additionally, the geotechnical study recommended grading specifications including selecting materials for fill and placing/spreading/compacting of fill. Additionally, the City of Pleasanton does not allow grading to occur between October 1 and April 30 unless erosion control measures are in place, subject to the review and approval of the Director of Engineering/City Engineer. Compliance with these recommendations are required as conditions of approval. Therefore, potential impacts would be less than significant. c) Site explorations conducted by PRA determined that the potential for liquefaction at this site is very low. The geotechnical analysis included recommendations to prevent landslides, lateral spreading, subsidence, liquefaction and collapse on the project site. The State of California provides 24 ical significance specifically designated by official action; 5.A stand of trees, the nature of which makes each dependent upon the other for survival or the area's natural beauty. 20 ive by having the additional two parcels.
