Home My WebLink About3.0 FEIR Revs to DEIR 3.0 REVISIONS TO THE DRAFT EIR 3.1 INTRODUCTION In response to comments on the Draft EIR during the 45-day public review period, the following revisions to the text of the Draft EIR have been made. Additions are shown as underlined text, and deletions are shown as otrikcthrough tcxt. 3.2 REVISIONS TO THE DRAFT EIR The following revisions have been made to the text of Table 2.0-1, Executive Summary. The same changes apply to the corresponding text in the body of the Draft EIR. Table 2.0-1, Mitigation Measure 4.4-5. The mitigation measure has been revised to allow for the relocation of the on-site monitoring well. Mitigation Measure 4.4-5: The applicant shall continue to provide TEC Accutite access to the project site to monitor groundwater at monitoring well MW -12, as required by the SMCHSA. Access to the monitoring well shall be provided until the SMCHSA has determined that the monitoring well is no longer required. All monitoring shall be conducted according to SMCHSA guidelines. The applicant may relocate the monitoring welL subject to approval of the San Mateo County Health Services Agency, insofar as the relocated well allows the same level of monitoring as the existing location. Table 2.0-1, Mitigation Measure 4.5-2. Mitigation Measure 4.5-2 has been revised to state that water from the storm drain interceptor will drain to the City's storm water drainage system. Mitigation Measure 4.5-2: The project applicant shall install a storm drain interceptor (also known as an oil/water or oil/grit separator) on site to remove oils and heavy particulates from stormwater, prior to draining to the sanitary sc,vcr storm water drainage system. Appropriate sizing of the unit relative to the impervious surface drainage area is important and shall be taken into consideration when choosing the interceptor unit model and size.

Mitigation Measure 4.5-4 has been revised to delete reference to rooftop retention as rooftop retention is not feasible. Downsprout retention is an adequate mitigation measure. Mitigation Measure 4.5-4: The project applicant shall incorporate rooftop or downsprout retention into all building plans. Table 2.0-1, Mitigation Measure 4.8-2. The text of the mitigation measure has been revised to indicate that the fair share payment will be paid by the applicant prior to the issuance of a Use and Occupancy Permit. Mitigation Measure 4.8-2. The project applicant shall be responsible for providing a fair share contribution for the following intersection improvements (with exception of the Forbes Boulevard/ Allerton Avenue all way stop which would be implemented solely by the applicant). These improT/ements shall be completed prior to occupancy. The full fair share payment shall be paid by the applicant prior to issuance of the Use and Occupancy permit by the City. Table 2.0-1, Mitigation Measure 4.8-3. The text of the mitigation measure has been revised to indicate that the fair share payment will be paid by the applicant prior to the issuance of a Use and Occupancy Permit. Mitigation Measure 4.8-3. The project applicant shall be responsible for providing a fair share contribution for the following intersection improvements +HeBe improT/ements shall be completed prior to full occupancy. The full fair share payment shall be paid by the applicant prior to issuance of the Use and Occupancy permit by the City. Table 2.0-1, Impact 4.8-4. The level of significance for this impact after mitigation has been added. It is identified as Less than Significant. Table 2.0-1, Mitigation Measure 4.8-5A. The erroneously repeated text in this mitigation measure has been deleted. Mitigation Measure 4.8-5A: The project applicant shall be responsible for providing a fair share contribution for the following improvements.

The capacity of single-lane diamond on-ramps has been revised to 2,000 vehicles per hour. The capacity of single-lane button hook or curving on-ramps has been revised to 1,800 vehicles per hour. Several Impact Sciences, Inc. 868-01 3.0-3 494 Forbes Blvd. Office/R&D Project Final EIR August 2007 3.0 Revisions to the Draft EIR revisions throughout Section 4.8 of the Draft EIR have been made to reflect this, as noted below: Page 4.8-20, On-Ramps On-ramp operation has been evaluated using planning-level methodology contained in HCM 2000. Capacity is dependent upon the free-flow speed of on- ramp traffic. For single-lane diamond on-ramps with higher speeds, capacity has been set at ~ 2,000 vehicles per hour. For single-lane button hook or curving on- ramps, capacity has been set at ~ 1,800 vehicles per hour.
