Environmental Reference (SER) website, Caltrans Project Development Procedures Manual, local and state CEQA Guidelines, and FHWA Technical Advisory 6640.81 Guidance on Preparing and Processing Environmental and Section 4(f) Documents. The Huitt-Zollars Team will prepare a NEPAICEQA Re-Validation form based on the form that is available on the Caltrans SER at the time that the analyses are performed. The Huitt-Zollars Team will provide a brief discussion of the validity of the information in the EIRIEA related to the following resources. • Geology, Soils, Seismicity • Hydrology, Water Quality, Stormwater Runoff • Hazardous Waste/Materials • Air Quality • Noise • Energy • Biological Resources • Floodplains • Land Use, Planning, and Growth • Community Impacts (Social, Economic) and Environmental Justice • UtilitieslEmergency Services • Parking • Traffic Transportation/Pedestrian and Bicycle Facilities • Visual/Aesthetics • Cultural Resources For most of these resources it is assumed that the brief discussion will be sufficient as conditions would not have changed sufficiently to substantially change the setting and impacts related to the proposed project. However, for some resources it is assumed that additional analyses will be required. To document changes in environmental impacts, if any, the following analyses will be conducted. It is assumed that all project components, features, and construction related activities will be located within the footprint that was identified and evaluated in the EIR/EA, that the following documentation will encompass all of the supporting environmental effort that is required for the re-validation, that no new mitigation will be identified or required, that no revisions to the EIR/EA itself will be required, and that no recirculation or public availability of the EIR/EA will be required. Based on the results of the analyses listed below, a determination will be provided on the NEPAICEQA Re- validation Form regarding the validity of the existing NEPA and CEQA documents and findings. It is assumed that the finding will be that the NEPA and CEQA document are still valid in conjunction with the listed analyses and that no further action is required related to environmental documentation. Task 3.2.1 Biological Resources A review of the currently listed federal and state species will be performed along with obtaining an updated species list from the United States Fish and Wildlife Services. In addition, a field reconnaissance will be performed to evaluate the potential for any newly listed or otherwise sensitive species to exist along the project alignment. A re- validation of the jurisdictional delineation of federal and state waters will also be performed to confirm that the results in the EIR/EA remain valid. It is assumed that only a field reconnaissance related to federal and state waters will be performed, that the original findings will still be valid, and that no new delineation or documentation will be required. However, since the project may actually reduce the amount of jurisdictional impacts, the obtaining of permits (401 Water Quality Certification, 404 Permit, and Section 1602 Streambed Alteration Agreement) is not included in this scope and cost. Once the updated field reconnaissance is completed then the need for permits will be discussed with the City and a scope and cost for this work can be submitted, if permits are required. The results of this analysis will be documented in a technical memorandum to be included as an attachment to the 25D-52
