SUMMARY: The Board will consider Addendum No. 3 to the Mitigated Negative Declaration (MND) for the Sleepy Hollow Steelhead Rearing Facility Raw Water Intake and Water Supply System Upgrade (Facility Upgrade) in compliance with the California Environmental Quality Act (CEQA) to allow disposal of up to 2,000 cubic yards of excavated material from the Facility Upgrade. The original design for the project anticipated balancing cut and fill for facility improvements on site; however, after review by Monterey County, the project was re-designed which resulted in excess cut material that cannot be placed at the Sleepy Hollow Facility.

MPWMD and California American Water staff identified a suitable site to place the material on a parcel owned by Cal-Am adjacent to the Facility Upgrade parcel, approximately ¾ of a mile from the Facility Upgrade Project site (see Figure 1). Impacts due to construction activities and mitigation measures at the Facility Upgrade site were previously considered with the MND. Impacts from transport and disposal of excavated material are similar to impacts considered for construction activities at the Project site. There would be no new impacts or mitigation measures required for disposal of material generated by the Project; however, an Addendum should be prepared for the additional activity. Findings of Environmental Review are attached as Exhibit 15-A.

RECOMMENDATION: Staff recommends that the Board adopt Resolution No. 2018-16 (Exhibit 15-B) approving the Addendum to the Mitigated Negative Declaration (MND) for the Sleepy Hollow Steelhead Rearing Facility Raw Water Intake and Water Supply System Upgrade.

DISCUSSION: MPWMD, Cal-Am, the California Department of Fish and Wildlife (CDFW), the National Marine Fisheries Service (NMFS), and the California State Coastal Conservancy (SCC) have been cooperating to upgrade the Sleepy Hollow Steelhead Rearing Facility (facility), which is situated in unincorporated Monterey County on the west bank of the Carmel River about 1 mile downstream of the former San Clemente Dam location. The project will allow for future changes in water supply, sediment, and debris flow that may affect the facility operations.

Up to approximately 2,000 cubic yards of excavated material could be generated from the facility upgrade project improvements. Based on geotechnical investigations and visual inspection of the Facility Upgrade site, excavated material will most likely consist of silty sand and sandy gravel. The proposed disposal sites are previously disturbed areas adjacent to the Carmel River where Cal-Am had located a surface water treatment plant (Filter Plant). The site was considered a non-contributing resource within the historical district established for the San Clemente Dam Reroute Project.

After completion of the San Clemente Dam Removal and Carmel River Reroute Project, the Filter Plant and residence (Site A in Figure 1 below) were removed, the site was regraded to a relatively flat profile, and reseeded with native grasses. Site A is about 10,400 square feet (< 0.25 acre) and contains disturbed soils comprised of silty sand, gravel, cobble, and some boulders characteristic of terrace areas adjacent to the Carmel River. Site B, where a water tank was removed, is about 2,900 square feet. Both sites are similar to the Facility Upgrade with upland grasses adjacent to oak habitat.

Potential impacts from the earthmoving activity will be similar to the impacts associated with other activities at the Facility Upgrade including impacts to air quality and sensitive species in upland habitats. Earthmoving activity that covers more than 2.2 acres per day and uses typical earthmoving equipment (scraper, loader, bulldozer, dump truck, etc.) would have potentially significant impacts; however, as described above, the disposal site is < 0.5 acre. All appropriate measures to reduce impacts to less than significant described in the adopted Mitigation and Monitoring Program would apply to the hauling and disposal of material at Sites A and B.

CEQA Action Required

CEQA Guidelines section 15162 “Subsequent EIRs and Negative Declarations” and 15164 “Addendum to an EIR or Negative Declaration” apply to this action. Under Section 15162, there are no new significant environmental effects or new mitigation measures necessary from the proposed earthmoving activity. The proposed earthmoving activity constitutes a technical change that under CEQA Section 15164 allows the Board to adopt an addendum to the existing MND, which has been amended by previous Addenda. The addendum for earthmoving activity consists of this staff note, Findings of Environmental Review (Exhibit 15-B), and Resolution 2018-16.

These are the previous actions that constitute the CEQA record:
