The review was conducted in accordance 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." The environmental statement has been reviewed and was approved by the City's Environmental Affairs Committee. As a result of the preliminary review, 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. Benjamin B. Nolan Public Works Director AIM:jd 8/22/85 it has been determined that: RIVERSIDE AVENUE RELIEF STORM DRAIN, PHASE 2 NEGATIVE DECLARATION BY CITY OF NEWPORT BEACH PUBLIC WORKS DEPARTMENT 1. PROJECT LOCATION: The proposed storm drain alignment is located approxi- mately 400 feet westerly of Riverside Avenue, crossing the 2800 block of Pacific Coast Highway from property line to property line, in the City of Newport Beach. 2. PROJECT DESCRIPTION: A storm drain catch basin will be built on the south side of Pacific Coast Highway. Reinforced concrete pipe or box -shaped con- duit, approximately 3-feet interior dimension, will be placed across Pacific Coast Highway to connect into the catch basin, thence into an existing storm drain pipe which passes through the basement of the adjacent Dominis building. 3. PROJECT GOALS: The project is needed to relieve the flooding which occurs in the vicinity of Riverside Avenue and Pacific Coast Highway. The highway must occasionally be closed because of the flooding. The general public and businesses in the area are the beneficiaries of the construction because of reduced travel times, and less inconvenience and damage to private property. 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 consistent with the General Plan of the City of Newport Beach and could not have a significant effect on the environment. 6. INITIAL STUDY: The Public Works Department of the City of prepared the Negative Declaration and its Initial Study in Article 7, Chapter 3, Guidelines for Implementation of the Environmental Quality Act of 1970. Copies of the Initial obtained from the Public Works Department during normal bu YOZ Benjamin B. Nolan Public Works Director LRD:jd 8/20/85 Newport Beach has accordance with California Study may be siness hours. RIVERSIDE AVENUE RELIEF STORM DRAIN, PHASE 2 INITIAL STUDY BY CITY OF NEWPORT BEACH PUBLIC WORKS DEPARTMENT A. CONFORMANCE WITH THE GENERAL PLAN This project is in conformance with the General Plan of the City of Newport Beach; in particular, the "Conservation of Natural Resources Element." B. ENVIRONMENTAL CHECKLIST FORM An Environmental Checklist Form (copy attached) has been completed as a por- tion of this study. The following statements, referenced to questions pre- sented on the checklist, explain all "yes" and "maybe" answers: 1.b. Reinforced concrete pipe or box -shaped conduit will be placed in a trench crossing Pacific Coast Highway; hence, the displacement and possible difference in recompactlion of soil in the vicinity of the conduit trench. 3.b. The storm drain construction will result in a faster rate of sur- face runoff from a completely developed commercial area. 3.c. Flood waters will flow toward Newport Bay through a newly installed storm drain pipe which is approximately 400 feet away from the location of the present outlet to the bay. The capacity of both outlets should be adequate to eliminate future flooding of the commercial area. 14.b. Completion of the proposal will result in lesser need for police manpower to close Pacific Coast Highway to vehicles and to reroute traffic during flood conditions. 14.e. Completion of the proposal will result in lesser need for street cleanup personnel subsequent to each flood. Conversely, the pro- posed storm drain will occasionally need to be cleaned of debris and silt buildup. 8/16/85 ENVIRONMENTAL CHECKLIST FORM w, I. Background 1.
