The Final EIR for the Bayfront Trail Gap Closure Concept (1220 to 1338 Bayshore Highway) is accepted as a reference document for use in reviewing future projects that involve the Bayfront Trail along 1220 to 1338 Bayshore Highway. 2. The mitigation measures contained in Exhibit A hereto are accepted as potential conditions for future development of the Bayfront Trail Gap Closure Concept and would either eliminate or reduce the potential significant environmental impacts of development of the concept to less than significant, and development of the concept would not have a significant effect on the environment. However, the actual development of the concept whether in whole or in part will require additional environmental review when actual development is proposed, and at that time the mitigation measures contained in Exhibit A shall be reviewed and revised as necessary to ensure conformance with Federal, State, and local law governing such development. MAYOR I, JUDITH A. MALFATTI, City Clerk of the City of Burlingame, do hereby certify that the foregoing resolution was introduced at a regular meeting of the City Council held on the 4 t h day of OCTOBER . 1999, and was adopted thereafter by the following vote: AYES: COUNCILMEMBERS: NOES: COUNCILMEMBERS: ABSENT: COUNCILMEMBERS: C:\WIP51\FILES\RESO\eirapprtrl3.pin.wpd GALLIGAN, JANNEY, KNIGHT, O'MAHONY, SPINELLI NONE NONE Bayfront Trail Gap Closure Concept PROJECT DESCRIPTION The alignment for the trail gap closure concept extends 1,113 linear feet northerly from the proposed project along the edge of the Bay from the vacant parcel at 1220 Bayshore Highway to the office property at 1338 Bayshore Highway. The 12 -foot wide asphalt -concrete trail would be constructed on a raised embankment with a rock riprap alone the shoreline for slope protection. The conceptual trail alignment crosses a total of seven parcels including four commercial properties and three vacant parcels, including easements for Easton Creek and the unnamed drainage channel from Highway 101. These properties include, from north to south, an office building at 1338-40 Bayshore Highway, the Hyatt Cinema at 1300 Bayshore, the Ramada Inn at 1250 Bayshore (which includes the drainage easement for Easton Creek), an office building at 1240 Bayshore, and a vacant lot (which includes the easement for the unnamed drainage channel from Highway 101). The project also includes portions of a vacant parcel on the bayward side, which largely consists of tidelands but which also includes a strip of upland along the shore. SUMMARY OF IMPACTS AND MITIGATIONS IMPACTS lI8XOROt'S_'1 1. The use of heavy construction equipment or die improper placement of material stockpiles could result in potential slope failures and subgmde damage. (Potentially Significant Impact) 1. The following measures will be implemented to avoid slope failures and subgrade damage: Avoid the use of heavy equipment in project grading and construction. The maximum equipment sizes should be Cat D4 or equivalent for dozers and Cat 943 or equivalent for track -wheeled loader. Other equipment should be generally limited in weight to approximately 10 tons per vehicle. Fully - loaded scrapers should not be used. Static compaction equipment without vibration should be used. In areas where the thickness of the existing fill has been reduced (i.e., by excavation for the project), light equipment should be used. Open excavations in soft Bay Mud cannot support rubber -tired equipment although light dozers with mud tracks may be used. No heavy equipment, stockpiles or other surcharges should be allowed within 25 feet of the landward embankment toe of slope.

The strong ground shaking expgcted at_ die trail alignment during a moderate to severe earthquake could potentially result in damage to structural elements such as the bridges and die seawall section. (Potentially Significant Impact) MITIGATION To avoid damage during a major earthquake, the bridges would be designed to Caltrans' seismic standards and the seawall section would be designed to withstand seismic loads, per the recommendations of the geotechnical engineer at the time of final design. (Less -than -Significant Impact with Mitigation) HYDROLOGY AND FLOODING 1. Unless mitigated, portions of the trail alignment would be subject to flooding during die 100 -year event. (Potentially Significant Impact) 2. The embankment fills for the trail would be subject to wave erosion which could ultimately result in damage to tite trail and its support fills. (Potentially Significant Impact) 1. To protect the trail from flooding and tidal action during the 100 -year event, the trail would be constructed at+10 feet NGVD to provide 3 feet of freeboard above the 100 -year flood elevation of +7 feet NGVD. (Less -than -Significant Impact with Mitigation) 2. The trail concept includes riprap shoreline protection which would provide armoring against wave action and prevent further shoreline erosion in the project area. (Less -than -Significant Impact with Mitigation) BIOLOGICAL RESOURCES The implementation of the trail concept would result in the loss of approximately 0. 14 acres of remnant salt marsli/mudflat habitat along the Bay shoreline and drainage charnels in the area. (Potentially Significant Impact) i, 1. To compensate for the loss of wetland habitat, it is likely that the Corps of Engineers and the resource agencies would require the creation of approximately 0.3 to 0.45 acres of replacement habitat in the vicinity of the trail alignment.

(Potentially • Areas of exposed soil will be stabilized prior to the rainy season (October 1 Sign ificant Impact) through May 1) by temporary or permanent measures such as seeding, mulching, sod stabilization, vegetative buffer strips, plastic covering, and/or application of ground base on areas to be paved. • Streets and parking areas subject to construction traffic will be damp swept regularly such that all visible debris and soil is removed. • If grading and construction activity occurs during the rainy season, silt fences, hay bales, and/or other measures will be employed along the landward side of the embankment fills to prevent silt runoff into the adjacent area. • Work within areas subject to tidal influence will be scheduled such that each increment of excavation, fill, and placement of riprap will be initiated and completed prior to the onset of the next tide event. • Silt fencing will be installed in certain areas at the project limits to provide a protective barrier for adjacent wetland and habitat areas. • The placement of riprap along the banks of Easton Creek and the unnamed drainage channel will be subject to a Section 1601-1603 Streambed Alteration Agreement with the California Department of Fish and Game, which would specify measures for controlling erosion in the channels. For construction activities conducted during the rainy season, erosion control practices will include the following additional measures: Silt fences, bay bales, and/or other measures will be employed along the landward side of the embankment fills to prevent silt runoff into the adjacent parking areas. Storm drain inlets will be protected by Tray bales or silt fences. Additional erosion control measures may be required per the City of Burlingame Storni Water Management and Discharge Control Ordinance. All erosion control measures will be included in the construction contract documents for the project.

These dust control measures will be included in the construction contract documents for the project (Less -than -Significant Impact with Mitigation) C:\WP51\FILES\CEQA\summareir2.pdw.doc A-4 EXHIBIT A R IMPACTS MITIGATION CONSTRUCTION IMPACTS - NOISE Noise levels would be temporarily elevated 1. The following measures will be implemented to mitigate during grading and construction. construction noise: (Potentially Significant Impact) • To miiuwnize equipment noise, standard practices such as proper muffling and maintenance of equipment will be employed. As required by the City of Burlingame Municipal Code, the hours of grading and construction will be limited to the hours of 7 AM to 7 PM on weekdays, 8 AM to 6 PM on Saturdays, and 10 AM to 6 PM on Sundays. • To minimize noise resulting from the placement of piles for the bridge abutments, the piles will not be driven but will be drilled and filled with reinforced concrete. To minimize noise disturbance to guests at the Ramada Inn, grading and construction in the vicinity of the hotel will be expedited to the extent feasible. These noise mitigation measures will be included in the construction contract documents for the project (Less -than -.Significant Impact with Mitigation) (Note: If the trail segment through the Ramada site is constructed in conjunction with construction at the hotel, the hotel will likely not open for business. If so, then noise impacts would not be a concern, and the final two mitigations would not be necessary.) C:\WP51\FILES\CEQA\summareir2.pdw.doe EXHIBIT A rm
