The review was conducted in compliance with the requirements of the California Environ- mental 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.

IMPROVIIONT OF THE IRVINE AVENUE-DOVER OVE-19TH STREET INTERSECTION ENVIRONMENTAL IMPACT REPORT - NEGATIVE DECLARATION CITY OF NEWPORT BEACH - PUBLIC WORKS DEPARTMENT 1. PROJECT LOCATION: The proposed project is located at the intersection of Irvine Avenue with Dover Drive and 19th Street in the Cities of Newport Beach and Costa Mesa. The corporate boundary divides the cities along Irvine Avenue. Development in the area is primarily residential with the exception of a fire station - park area in the southeasterly quadrant of the intersection. 2. PROJECT DESCRIPTION: The work consists of: reconstruction of the intersection and widening of the 19th Street and Dover Drive legs of the intersection; recon- struction of an inadequate storm drain system in the intersection; reconstruction of a portion of the County Flood Control Channel (G02) to accommodate widening of Dover Drive; and installation of a traffic signal system at the intersection. All streets at the intersection are primary arterial highways. Storm drain reconstruc- tion is in compliance with the City of Costa Mesa's and Orange County Flood Control District's Master Plans of drainage. All widening is within existing street rights of way. 3. PURPOSE OF THE PROJECT: (a) To provide adequate capacity and safety at the intersection to meet present and future traffic demands. (b) To widen and realign 19th Street and Dover Drive to provide safer crossing of Irvine Avenue. (c) To reconstruct and upgrade an existing inadequate storm drain system at the intersection. Major flooding of travel lanes occurs at present during storms of lcw to median intensities: (d) To control the intersection with a traffic signal system in order to provide for a safer and more efficient flow of traffic at this major intersection. 4. DISCUSSION OF ENVIRONMENTAL IMPACTS: (a) Land Resources Construction of this project will not require the use of any land not presently in dedicated street rights of way. A portion of the open area adjacent to the County Flood Control Channel will be used for widening Dover Dri•vet this will necessitate removal of five trees, hcwever they will be replaced in the new parkway adjacent to Dover Drive. The improvements to traffic safety, potential to flooding, and traffic capacity resulting from this project are felt to off- set this change in use. (b) Human Resources There will be no effects on human resources due to this project since the work is within existing street rights of way and no relocation of residences will be made. 5. BASIS FOR NEGATIVE DECLARATION: The proposed project has been reviewed in conjunction with Sections 15081 and 15082 of Article 7, Chapter 3 (Guidelines for Implementation of the California Environmental Quality Act of 1970), Title 14, Division 6 of The California Administrative Code. The criteria set forth in the above sections indicate that the proposed project will not have a significant environmental impact. A copy of an informational fact sheet is attached for reference hereto. IMPROVIlipT OF THE IRVINE AVE.--DOVER D E--19TH STREET INTERSECTION FACT SHEET TO DETERMINE IF PROJECT HAS SIGNIFICANT ENVIRONMENTAL EFFECT A. CONFORMANCE WITH CITY AND COUNTY GENERAL PLANS This project is in conformance with the City's current Master Plan of Streets and Highways element of the General Plan. The project is also in conformance with: The City of Costa Mesa --Master Plan of Drainage, Orange County Flood Control District's Master Plan of Drainage, and the County's Master Plan of Arterial Highways. Irvine Avenue, Dover Drive, and 19th Street are classified as primary arterial highways on the City's.and County's Master Plans. Minimum width for a primary arterial highway is 84 feet, curb to curb. Existing street widths curb to curb at the intersection are: Irvine Avenue 91 feet, Dover Drive 40 feet, and 19th Street 36 feet. B. LAND USE AND AESTHETICS Street widening for this project will be accomplished within existing public right-of-way. A portion of open area adjacent to the Orange County Flood Con- trol District's G-02 Channel will be utilized for widening of Dover Drive. C. GEOLOGIC HAZARDS This project is in a general area of geologic concern, however no significant geologic hazards are within the area encompassed by the improvements. Extensive grading will not be required. D. HUMAN RESOURCES There will be no effects on human resources due to this project since the work is within City right-of-way, and no relocation of residences or major alterations to private property will be made. E. FLOODING, EROSION, AND SILTATION Project planning calls for construction of this project to occur during late spring and summer, prior to the normal rainy season in this area. Construction during those periods should preclude the possibility of flooding, erosion, and any sub- sequent siltation of material downstream. The project specifications will require the contractor to employ sufficient erosion control measures during construction to further reduce the possibility of siltation. F. GROUNDWATER There are no known aquifers in the area of the project. G. NOISE LEVEL Widening of the street should not substantially alter the ambient noise levels for the surrounding area, since the intersection modifications are not expected to cause a major increase in traffic use, but rather to facilitate the use of the intersection. 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 hours to insure the minimum disturbance to neighboring residents, and the operations will cease upon completion of the project. H. SECONDARY CONSEQUENCES It has been determined that no secondary consequences will arise from the, minor primary consequences related to this project. I. AIR RESOURCES This project will not significantly increase or decrease the vehicle emissions in this air quality region. Dust control procedures will be required during construction specifications. total volume of under the project J. VEGETATION AND ANIMAL LIFE There are no known rare or endangered species or habitats of such species of animal or plant life within or adjacent to the project area. The widening Will necessitate the removal of five eucalyptus trees adjacent to the County Flood Control District's G-02 Channel. A parkway area will be created adjacent to the channel and three to four trees are to be planted in this area. K. SHORT TERM IMPACTS The only short term impacts anticipated are those associated with any street or underground construction. They are specifically noise and motorist inconvenience during construction. Traffic control provisions are made in the project specifi- cations to provide for the smooth and continued flow of traffic thru the inter- section. These impacts are not considered to have a significant effect on the environment. L. SUMMARY This project, being essentially a reconstruction of an existing intersection, will not have a significant effect on the environment.
