The Public Works Department will supply the committee with any additional information which may be required to make findings and recommendations in this matter. The tentative project schedule calls for construction to start in August 1975; final design of the project will occur this fiscal year. Joseph Devlin Public :rks Director SB:hh Attachments R‘EGE]VED.

The review was conducted in compliance with the requirements of The California Environmental Quality Act of 1970, the State "Guidelines for Implementation of the California Environmental Quality Act of 1970", and the City's "Policies and Procedures for Implementing the California Environmental Quality Act". As a result of the preliminary review, it has been determined that: 1. The project is approved. 2. The project will not have a significant effect on the environment. 3. An Environmental Impact Report has not been prepared. A Negative Declaration has been prepared and is attached hereto. i.seph T. Devlin ublic • ks Director, RCE 9537 SB:hh Attachment • .41 March 5, 1975 BALBOA AVENUE STORM DRAIN IMPROVEMENTS MARINE AVENUE TO THE GRAND CANAL EIR - NEGATIVE DECLARATION BY CITY OF NEWPORT BEACH - PUBLIC WORKS DEPARTMENT 1. Location: The proposed project is located on Balboa Island in the City of Newport Beach. 2. Project Description: The work consists of construction of a stormwater pump station in Balboa Avenue at The Grand Canal and construction of a gravity storm drain collection system in Balboa Avenue from Marine Avenue to the Grand Canal. 3. Purpose of Project: The project will provide for the replacement of an existing deficient gravity storm drain system in Balboa Avenue at the Grand Canal. During periods of high tides the system cannot function and, if a rainstorm is concurrently occurring, flooding of adjacent private property results. Construction of the project will alleviate the potential for severe flooding. 4. Discussion of Environmental Impacts: - a) Land Resources The proposed project is located within existing public street right - of way. b) Geologic Hazards The project lies within a seismic hazard area of potential liquefaction; however, the contemplated construction will not increase or decrease the hazard. c) Secondary Consequences The project will not increase or decrease stormwater flow into the Bay. Siltation and floatable pollution will be reduced by collection prior to discharge. 5. Basis for Negative Declaration: The proposed project has been reviewed in conjunction with Sections 15081, 15082, and 15083, Chapter 3 -- Guidelines fdr Implementation of the California Environmental Quality Act of 1970, Division 6, Title 14, California Administrative Code. The project is not in conflict with the environmental goals and plans of the community; it does not have any aesthetic effect; it does not affect animal or plant life;, and it does not affect the air quality, water quality, and the ambient noise levels of the adjoining areas. Review of the criteria set forth in the above noted 'sections indicates that the proposed project will not have a significant environmental impact. A copy of the informational fact sheet is attached for reference. • March 5, 1975 CITY OF NEWPORT BEACH - PUBLIC WORKS DEPARTMENT BALBOA AVENUE STORM DRAIN IMPROVEMENTS MARINE AVENUE TO THE GRAND CANAL FACT SHEET TO DETERMINE IF PROJECT HAS A SIGNIFICANT ENVIRONMENTAL EFFECT A. Conformance with the City General Plan The project is in conformance with the Balboa Island Drainage Study, an area - wide plan for drainage improvements on the island completed in 1974. The plan was approved by the City Council in January 1975. This project is in conformance with the City's General Plan. B. Land Use Construction of the project will not require acquisition of right-of-way. The storm drain system will be located within existing public street right-of-way. Land use on Marine Avenue i,s commercial, and on Balboa Avenue is residential. C. Human Resources The project will not require the relocation of any homes,businesses or people. D. Geologic Hazards A potential seismic hazard due to liquefaction exists in this area. However the project involves shallow excavations and reconstruction of street surfacing and will not increase or decrease any potential damage due to the seismic hazard. E. Flooding, Erosion, or Siltation Project planning calls for construction of this project to occur during the summer and early fall months prior to the normal rainy season for this region. Construction during that period should preclude the possibility of flooding, erosion and any subsequent siltation of materials in Newport Bay. •The project specifications will require the contractor to employ erosion control measures during construction to further reduce any possibility for siltation. F. Groundwater Groundwater exists in the area from seawater tidal sources; subsequently de - watering by pumping will be required for structure and pipeline construction. A permit from the Sanitation Districts of Orange County will be obtained to allow dewatering effluent to be discharged into the sanitary sewer system. G. Noise Level • During construction, noise levels may rise due to operations which are necessary to construct the project. However these operations will be limited as to working' Balboa Avenue Storm Drain Improvements Fact Sheet to Determine if Project has a Significant Environmental Effect Page 2. hours to ensure a minimum of disturbance to residents and commercial establish- ments. During operation of the stormwater pump station noise levels may rise, however noise attenuation will be considered of prime importance in the design of the facility and acceptable noise levels will be maintained, during operation of the station. H. Archeological and Paleontological Sites There are no known archeological or paleontological sites within the project limits. However.should grading operations encounter significant fossils or artifacts, construction scheduling will be altered to allow sufficient time for investigation and recovery of finds. I. Air Resources This project will not affect the air quality of this region. Dust control measures will be required during construction under the project specifications. J. Vegetation and Animal Life There are no known rare or endangered species of animal or plant life within or adjacent to the project area. K. Water Resources The proposed project will not affect the water resources in the area. L. Secondary Consequences The proposed project will not cause an increase or decrease in the volume of stormwater entering Newport Bay. The wetwell of the stormwater pump station will provide for silt removal and collection of floatable materials, thus improving water quality. M. Short -Term Impacts The only short term impacts anticipated.for this project are a slight amount of motorist inconvenience and some construction noise. These impacts are not considered to be significant. N.' Summary The project does not appear to have a significant effect on the environment. • Ir Qgavf. ron ="'�. • -` oeiv6 �•% � .
