April 29.1998 Mike Bardin, Assistant General Manager Date of Draft Report Leucadia County Water District Tune 30.1998 Date of Final Report /OACHMENT>*^W Screencheck Draft Mitigated Negative Declaration Saxony Pump Station Rehabilitation Project SECTION 3 PROPOSED riNDINO OP NO SIGNIFICANT EFPECT LCWD finds that the project will not have a significant adverse effect on the environment based on the results of the Initial Study/Environmental Checklist (see Section 4) and the Environmental Evaluation Discussion (see Section 5, Discussion of Environmental Impacts). Measures have been incorporated into the project to ensure that any impacts will be less than significant. A Mitigated Negative Declaration is therefore proposed to satisfy the requirements of CEQA (PRC 21000 et. seq. 14 Gal Code Regs 15000 et. seq.). This conclusion is supported by the following: 3.1 NO SIGNIFICANT EFFECT FINDING 1. Land Use: The proposed project would be compatible with the existing and surrounding land uses adjacent to the project site. Measures have been incorporated into the project design to reduce potential impacts associated with noise from the proposed standby generator and wetland disturbance (see Section 3.2, Mitigation Measures and Monitoring Program, and Section 5-1, Land Use and Planning). 2. Population and Housing: The capacity of the existing station is not being increased, therefore the proposed project would not generate additional population, and the approval of the project would have a less than significant effect on human population and housing (see discussion under Section 5.2, Population and Housing). 3. Geologic Problems: No long-term geologic problems would occur with implementation of measures recommended as a part of the geotechnical investigation conducted for the project (see discussion under Section 3.2, Mitigation Measures and Monitoring Program, and Section 5.3, Geologic Problems). 4. Water: No long-term adverse impact to local waters is anticipated as a result of this project. Measures are incorporated into the project which reduce project effects associated with potential discharge of sediments and dewatering activities into the Batiquitos Lagoon to less than significant (see Section 3.2, Mitigation Measures and Monitoring Program, as well as the discussion under Section 5-4, Water). .ASSOCIATE 1545~6° April 24,1998 10 Screencheck Draft Mitigated Negative Declaration Saxony Pump Station Rehabilitation Project 5. Air Quality: Measures are incorporated into the project which, reduce effects associated with generation of paniculate matter less than 10 microns (FM10) and emissions from the standby generator to less than significant (see Section 3.2, Mitigation Measures and Monitoring Program as well as the discussion under Section $.$, Air Quality). 6. Transportation and Circulation: It is not anticipated that construction of the project would affect vehicle, bicycle or pedestrian traffic on La Costa Avenue. The first phase of construction would involve the clearing of the vehicle turnout area. Following completion of the turnout, construction equipment for the access road and miscellaneous equipment placement will be stored within the turnout area. No construction equipment would operate or be stored within the La Costa Avenue right-of-way. 7. Biological Resources: Measures are incorporated into the project to mitigate direct impacts to biological resources associated with grading for the maintenance access road and turnaround area. Measures are also incorporated into the project which reduce indirect biological resource impacts associated with construction adjacent to the Batiquitos Lagoon and potential noise impacts associated with the standby generator (see Section 3.2, Mitigation Measures and Monitoring Program, as well as the discussion under Section 5-7, Biological Resources). 8. Energy and Mineral Resources: The proposed project's long-term usage of diesel fuel in association with the standby generator is not anticipated to exceed the use and demand anticipated by SDG&E (see discussion under Section $.8, Energy and Mineral Resources). 9. Hazards: Observance of standard safety measures during construction and operation/ maintenance will reduce the risk of explosion or release of hazardous substances to a less than significant level. Traffic control measures incorporated into the project construction process reduce potential hazards to pedestrian and bicyclists (see discussion under Sections 3.2, Mitigation Measures and Monitoring Program, and 5- 9, Hazards). 10. Noise: Measures are incorporated into the project which reduce noise impacts associated with construction activities to less than significant. Measures have been incorporated into the design of the proposed standby generator to avoid potential noise impacts to surrounding residences and sensitive wildlife species (see Section 3.2, Mitigation Measures and Monitoring Program, as well as the discussion under Section $.10, Noise). EBIUDHI&ASSOCUTIS 1545-60 April 24, 1998 11 C Screencheck Draft Mitigated Negative Declaration Saxony Pump Station Rehabilitation Project 11. Public Services: The proposed project does not involve any new residents, and would not generate a demand for public services; therefore, no impact to public services would occur (see discussion under Section 5.11, Public Services). 12. Utilities and Service Systems: Existing capacity of the station will not be increased, therefore implementation of the project would not involve a demand for new services and utilities other than those constructed. The project design proposes undergrounding of existing telephone and electrical utilities located within the area proposed for the access road and SDG&E's quitclaim of their easement (see discussion under Section 5-12, Utilities and Service Systems). 13. Aesthetics: Existing pump station facilities would be placed underground as a part of the project with the exception of two enclosures. Considering the proximity to the roadway, the enclosures and access road are considered to be a visual extension of La Costa Avenue. Therefore, no impacts to aesthetics would result from the proposed project (see discussion under Section 5-43, Aesthetics). 14. Cultural Resources: There is a potential for cultural resources to be located in the area to be disturbed in association with project implementation. Based on a paleontological analysis completed for the La Costa Road Widening project, geological formations underlying the project vicinity include the Santiago Formation, Del Mar Formation, and Pleistocene marine terrace deposits. Paleontological resource potential within these formations is considered to be high. Measures have been incorporated into the proposed project to reduce potential impacts to cultural and paleontological resources to less than significant (see Section 3.2, Mitigation Measures and Monitoring Program, and discussion under Section 5.14, Cultural Resources). 15. Recreation: Implementation of the proj ect would not affect existing or planned recreational facilities (see Section 3.2 and discussion under Section $.1$, Recreation). 3.2 MITIGATION MEASURES AND MONITORING PROGRAM LCWD has summarized here the various requirements imposed on the project to reduce impacts to less than significant: 1545-60 April 24,1998 12 Screencheck Draft Mitigated Negative Declaration Saxony Pump Station Rehabilitation Project Land Use and Planning: To comply with the City of Carlsbad's LCP, the following measures will be incorporated into the project: • Prior to construction, LCWD shall obtain a Coastal Development Permit from the City of Carlsbad. • Wetlands impact mitigation shall be a condition of the permit. As discussed in Section 5-7, Biological Resources, LCWD will mitigate for impacts to wetlands. • An established mitigation area adjoins the project site to the north. The construction plans shall state that the Contractor for the proposed project will not disturb any areas outside of the work area. Therefore, there will be no grading, landscaping or other disturbance within the mitigation area. In addition, measures required to reduce potential impacts from standby generator noise (See Noise, below) and direct impacts to wetlands (see Biological Resources, below) will reduce identified inconsistencies with the environmental goals of the relevant land use plans to below a level of significance. Geologic Problems: • Plans and specifications for the proposed project shall incorporate standard geotechnical recommendations as presented in the AGRA Geotechnical Report. Measures are recommended in the areas of site preparation and grading, slabs on grade, retaining walls, flexible pavement structural section, corrosion and geotechnical and construction review. The complete AGRA investigation including the recommendations, is included as Attachment A to this report. • Erosion control measures, such as the use of sandbags, will be implemented to reduce potential soil erosion during construction. Water : Prior to construction, the Contractor shall obtain Order No. 96-41-NPDES Permit #919002 from the RWQCB for dewatering activities. (The official title of the permit to be obtained is: General Waste Discharge Requirements for Groundwater and Similar Waste Discharges for Some ifrni* Cr'Mf*"" -- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^» April 24,1998 13 c Screencheck Draft Mitigated Negative Declaration Saxony Pump Station Rehabilitation Project Construction and Remediation Projects to Surface Waters Within San Diego Region Except San Diego Bay.) The permit may be conditioned to protect the water quality in the project vicinity. These conditions may include treatment, discharge sampling, monitoring and reporting. Air Quality: • LCWD will require, as part of the construction documents, measures to reduce PMi0 dust emissions including the use of watering and other dust control measures during project construction. • The Contractor shall obtain a Certificate of Registration from the SDAPCD for operation of the standby generator to ensure that emissions do not result in adverse impacts to ambient air quality. Biological Resources: • Prior to construction, impacts to 0.04 acre of coastal sage scrub will be mitigated by the acquisition (by LCWD) of 0.08 acre of coastal sage scrub within an approved mitigation bank or planned open space (preserve) area. If not previously encumbered, appropriate easements guaranteeing permanent preservation will be obtained. Prior to construction, LCWD will devise a revegetation plan and revegetate 0.42 acre of southern willow scrub/mule fat scrub located offsite which is similar in species richness and structure to that removed. LCWD will devise a Concept Plan which will include: 1) the location of the project, 2) applicant responsibilities, 3) revegetation contractor responsibilities, 4) ownership status and, 5) present and proposed uses of the mitigation area. LCWD will also devise an Implementation Plan which will include: 1) timing of construction activities, 2) timing of revegetation effort, 3) revegetation materials, 4) site preparation, 5) planting plan and, 6) irrigation plan. A Maintenance Plan will also be devised by LCWD. Prior to construction these plans will be reviewed and approved by local resource agencies including the California Department of Fish and Game. This revegetation effort will be subject to a 5- year monitoring period and performance criteria as dictated in the revegetation plan. • To reduce the generator noise to a one-our average noise level of 60 dB or less at the adjacent biological habitat area, a minimum six-foot high noise barrier will be designed by a qualified acoustician and constructed along the north side of the generator. The barrier should be l&ASSOClATESl April 24,1998 14 Screencheck Draft Mitigated Negative Dedaration Saxony Pump Station Rehabilitation Project aligned so as to connect to the east and west side retaining walls. Due to access requirements, the barrier cannot be constructed of masonry material, therefore, it is recommended that tongue and groove boards with a minimum thickness of 3/4-inch be used as a barrier material. Also, a sound absorbing material such as Pyrock Acoustement 40 (with a minimum thickness of 1-5/8 inches) or equivalent, should be applied to the interior surfaces of the retaining wall. Construction will not occur during the breeding seasons of three bird species (California gnatcatcher February 15 through August 15; least Bell's Vireo April 1 through July 31; and southwestern willow flycatcher May 22 through July 31). If construction must occur during the breeding season, weekly surveys must be conducted by a qualified biologist to determine the presence/absence of the potentially affected species. If one or more of the species is detected, construction must stop until noise levels can be demonstrably reduced to a level below 60 dB. Hazards: • Measures incorporated for Transportation above (see5.6-athrough5.6-e) reduce construction impacts to emergency routes to a level below significance. Noise: • The hours of construction shall be restricted to 7AM to sunset Monday through Friday, and SAM to sunset on Saturdays. An exemption to construction outside these times shall be required for activities which extend beyond these times. Cultural/Faleontological Resources: • A qualified paleontological monitor (certified by the County of San Diego) will be present during open excavation activities. LCWD will also contract with a qualified archaeologist (certified by the County of San Diego) to conduct monitoring during construction activities. • If any paleontological or cultural resources are discovered during construction, grading would be temporarily delayed to allow for recovery of these resources. I&ASSOC1ATIS 1545-60 April 24,1998 15 Screencheck Draft Mitigated Negative Declaration Saxony Pump Station Rehabilitation Project Recovered resources would be cataloged and stored in a museum. Following construction, a report will be submitted to the District by the archaeologist and paleontologist that documents the results of the monitoring. i&ASSOCUTiSl April 24,1998 16
