The review was conducted in accor- dance 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, it has been deter- mined 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. Benjamin B. Nolan Public Works Director BBN/np 7-24-84 FERNLEAF AVENUE STORM DRAIN AND DAHLIA AVENUE SEWER MAIN REPLACEMENT NEGATIVE DECLARATION BY CITY OF NEWPORT BEACH PUBLIC WORKS DEPARTMENT 1. PROJECT LOCATION: Storm drain replacement is located in the 500 and 600 blocks of Fernleaf Avenue, in the 400 block of Dahlia Avenue, and in the 2500 block of First Avenue, all in Corona del Mar. Sewer main replacement is located in the 400 block of Dahlia Avenue, in the 2500 block of First Avenue, in the 400 block alley between Carnation and Dahlia Avenues, and through Begonia Park between Bayside Drive and First Avenue, all in Corona del Mar. 2. PROJECT:DESCRIPTION: A hydraulically -deficient, 24-inch diameter storm drain in Fernleaf Avenue is to be bypassed with 360 linear feet of 42-inch-diameter pipe. A hydraulically-deficient,36-inch diameter storm drain through private property in the 400 block between Carnation and Dahlia Avenue is to be by- passed with 450 linear feet of 42-inch-diameter pipe in Dahlia and First Avenues. An 8-inch-diameter sewer main through private property in the 400 block between Carnation and Dahlia Avenues is to be bypassed with 525 linear feet of 8-inch diameter pipe in Dahlia and First Avenues. A 110-linear-foot by 8-inch-diameter sewer in the 400 block alley between Carnation and Dahlia Avenues will be replaced with' a reverse -flowing 8-inch-diameter sewer. And a hydraulically -deficient, 8-inch-diameter sewer through Begonia Park will be replaced with adhydraulicaliy-adequate 8-inch-diameter pipe. Replaced or bypassed sewer and storm drain pipes in Fernleaf Avenue, the 400 block, the alley, and Begonia Park will be backfilled and abandoned in„place. 3. PROJECT GOALS: The project will provide (1) relief from rainstorm runoff flooding in Fernleaf Avenue and in the sump area near Second and Dahlia Avenues; (2) relief from recurrent sewer stoppages in the Begonia Park area; (3) in- creased access to sewer and storm drain systems for City maintenance forces; (4) relief from City's exposure to liability whenever downstream storm drain constrictions cause flooding upon and damage to private property; and finally (5) new conduits to replace those of partial longevity. 4. EFFECT ON THE ENVIRONMENT: There will be no significant long-term irrevers- ible or irretrievable effects on the environment. There will be minimal, acceptable short-term disturbances of the environment due to construction activity. 5. BASIS FOR NEGATIVE DECLARATION: This project is consistent with the General Plan policies of the City of Newport Beach and could not have a significant effect on the environment. -t le I 1 • • Fernleaf Avenue Storm Drain and Dahlia Avenue Sewer Main Replacement Negative Declaration Page 2 6. INITIAL STUDY: The City of Newport Beach Public Works Department has prepared this Negative Declaration and its Initial Study in accordance with Article 7, Chapter 3, Guidelines for Implementation of the California Environmental Quality Act of 1970.

CONFORMANCE WITH THE GENERAL PLAN This project is in accord 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 (attached) has been completed as a portion 'of this study. The following statements, referenced to questions presented on the checklist, explain all "yes" and "maybe" answers: II.3.b Construction of new catch basins and transmission pipe will slightly increase the runoff rate in the vicinity of the Sump condition at Second and Dahlia Avenues; however, the increased runoff rate will preclude the flooding of private property which has occurred hereto- fore during heavy rain storms. II.14.e Construction of storm drain improvements will result in the need for periodic cleaning of debris from inlet catch basins; however, a correspondingly lesser amount of debris will need to be cleaned from public and private property which flood during heavy rain storms in absence of She improvements. Also, less cleaning will be re- quired in the new storm drain system than is required in the exist- ing deficient system. -t 7/19/84 • ENVIRONMENTAL CHECKLIST FORM • I. Background 1.
