6.2A Page 25 . Mitigation Measure BIO-15a, b, and c: would address impacts on State-regulated habitats, including isolated wetlands (i.e., wet meadow, freshwater marsh, seasonal) and riparian habitat throughout the alignment Impact BIO -17: Conflict with local tree preservation ordinances by removing or damaging locally protected trees. Project excavations and pipeline and valve vault construction would require the removal of mature native and non-native trees that qualify as significant, heritage~ or otherwise locally protected trees. In addition, grading or trenching within their drip lines could result in tree mortalities or reduced tree vigor, leading to future mortalities. The jurisdictions in which the Project would be constructed include the cities of Fremont, Newark, East Palo Alto, Menlo Park~ Palo Alto~ and Redwood City, and unincorporated San Mateo County. These jurisdictions have ordinances that define significant and/or heritage trees and regulate their removal or pruning. Potentially significant tree removal impacts would occur in Fremont; in Newark; in Menlo Park; in Redwood City, and in unincorporated San Mateo County . Mitigation Measure BIO 17a: Tree survey . Mitigation Measure BIO 17b: Replace significant, heritage, landmark, or othetwise protected trees . Mitigation Measure BIO- 17 c: Perform necessary pruning; plant replacement trees; monitor remedial tree plantings Impact CR -la: Impacts on archaeological resource sites tbat are potentially NRHP and CRHR eligible. Construction of the Project has the potential to affect significant archaeological sites. The pipeline segments in the East Bay and Peninsula would be installed below ground by a combination of open cut trenching along the majority of the right of way for BDPL Nos. 1 and 2 and trenchless methods, such as micro tunneling or jack-and-bore, under railways, major thoroughfares, and certain drainages. Presently, no archaeological sites within the proposed study area have been listed in either the California Register of Historical Resources (CRHR) or the National Register of Historic Places (NRHP). Five prehistoric archaeological sites previously had been recorded, and one additional prehistoric site was located during the pedestrian reconnaissance of the study area. Direct impacts from trenching for BDPL No. 5 would be potentially significant for sites retaining integrity, given the paucity of investigations of similar prehistoric sites in the South Bay. . Mitigation Measure CR-la: Retain a qualified archaeological consultant; undertake an archaeological testing program (A TP); conduct an archaeological monitoring and/or data recovery program, if required; suspend construction, as necessary .
