The environmental statement has been reviewed City's Environmental Affairs Committee. As a result of the preliminary review, it has 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. - Lam, a Benjamin B. Nolan Public Works Director AIM:dw 5-18-89 and was approved by the been determined that: AVON STREET IMPROVEMENT & RIVERSIDE AVENUE STORM DRAIN NEGATIVE DECLARATION BY CITY OF NEWPORT BEACH PUBLIC WORKS DEPARTMENT 1. PROJECT LOCATION: The proposed improvements are located in Riverside Avenue between Avon Street and Cliff Drive and in the 300 feet of Avon Street westerly of Riverside Avenue, all in the City of Newport Beach. 2. PROJECT DESCRIPTION: Dual 24-inch diameter storm drain pipe will connect to existing pipe in Avon Street and extend easterly to a structure in Riverside Avenue. From that point, a single 24-inch diameter storm drain pipe will be laid uphill in Riverside Avenue to terminate at Cliff Drive. Inlets to the drain will be built at Avon Street (1), at Cliff Drive (3) and adjacent to Cliff Drive Park (2). Curb, gutter, sidewalk and 10 perpendicular parking stalls will be built along the northerly side of Avon Street. Curb access ramps will be included in the new curb return construction at Riverside Avenue. Avon Street pave- ment will be reconstructed to 300 feet westerly of Riverside. A new commer- cial driveway approach, plus a street light, will be installed to serve the driveway to off-street parking for the Stuft Noodle Restaurant building. 3. PROJECT GOALS: The proposed project will provide the subterranean drainage system needed to keep Avon Street, Riverside Avenue and Pacific Coast Highway from inundating and silting during and after intense rain storms. The improvements should eliminate the need to close these streets as the result of storm activity, and assist in the enforcement of parking regula- tions along Avon Street. The improvements will also approve the appearance of the vicinity, and provide a safer walkway for pedestrians using Avon Street or Riverside Avenue. 4. EFFECT ON THE ENVIRONMENT: There will be no significant long-term irrever- sible or irretrievable effects on the environment. There will be minimal, acceptable short-term disturbances caused by construction activity. 5. BASIS FOR NEGATIVE DECLARATION: This project is not inconsistent with the General Plan of the City of Newport Beach and will not have a significant effect on the environment. 6. INITIAL STUDY: The Public Works Department of the City of Newport Beach has prepared the Negative Declaration and its Initial Study in accordance with Article 6, Chapter 3, Guidelines for Implementation of the California Environmental Quality Act. Copies of the Initial Study may be obtained from said Department during normal business hours. - au Benja(nin B. Nolan Public Works Director LD:dw AVON STREET IMPROVEMENT & RIVERSIDE AVENUE STORM DRAIN INITIAL STUDY BY CITY OF NEWPORT BEACH PUBLIC WORKS DEPARTMENT A. CONFORMANCE WITH THE GENERAL PLAN: This project is not inconsistent with the environmental plans and goals established by the General Plan of the City of Newport Beach. B. ENVIRONMENTAL CHECKLIST FORM: An Environmental Checklist Form has been completed as a portion of this study. The following statements, referenced to questions presented in the checklist, explain all "yes" and "maybe" answers: II.1.b. Trenches will be excavated in Avon Street and in Riverside Avenue for placement of 24-inch diameter storm drains. The storm drain trenches will then be backfilled, compacted and resurfaced with asphalt. II.1.c. The northerly side of Avon Street from Riverside Avenue to 300 feet westerly will be cleared of asphalt pavement, graded and compacted. Concrete curb and gutter will then be built to connect to existing curb and gutter in Avon Street and in Riverside Avenue. Concrete sidewalk will also be built along the new curb and gutter, and along Riverside Avenue to join an existing concrete sidewalk. Curb access ramps and a commercial driveway approach will be built along the Avon Street improvement. Four catch basins will be built along the Riverside Avenue storm drain alignment. Two drop inlets will be built in Cliff Drive Park to accept drainage flow from the park and from Newport Heights. II.3.b. The proposed construction of curb, gutter, pavement and a storm drain system may slightly reduce absorption rates and increase the rate and amount of surface runoff. II.7. A single street light, with 24-foot pole height and cutoff luminaire, will be installed adjacent to the driveway approach which serves the off-street parking lot for the Stuft Noodle Restaurant building. II.13.b The proposed construction of Avon Street improvements will result in the net loss of 10 parking spaces; however, 1) 6 of the lost spaces are along the southerly curb of Avon Street, which is too narrow to accom- modate parking after the street is improved to City standards, and 2) the remaining 4 lost spaces are located in public property in a manner which may not be accessed after street improvements have been built along Avon Street. II.14.e. The proposed construction will necessitate routine maintenance of the street and storm drain; however, that effort is exceeded by current maintenance requirements along Avon Street, Riverside Avenue and Pacific Coast Highway after storms inundate and deposit silt upon this low lying area. II.16.e. The proposed construction will provide for the extension of a subterranean drain system into a drainage area where no such facility now exists. I; ENVIRONMENTAL CHECKLIST FORM I.
