The review was conducted in accordance with the requirements of the California Environmental Quality Act of 1970,,the State "Guideline$ foe, Implemegtation of the California Environmental Quality Act of 1970", and, the City's "Policies .and Procedures for Implementing the California EnvironmentalQuality Act." The ervironmentai'statement has been reviewed and was approved by City's Environmental Affairs Committee. As a result of the preliminary review, it has been determined that: 1. The project Is approved., 2. The project wil1_'not�have a significant effect on the environ- ment. 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:jd 10/12/84 • .v PEARL AVENUE STORM DRAIN NEGATIVE DECLARATION BY CITY OF NEWPORT BEACH PUBLIC WORKS DEPARTMENT. 1. PROJECT LOCATION: The storm drain construction is located in Pearl Avenue between Park Avenue and Newport Bay and along the South Bayfront between Agate and Garnet Avenues, all on Balboa Island in the City of Newport Beach. 2. PROJECT DESCRIPTION: A 21-inch-diameter storm drain pipe will be installed in Pearl Avenue to convey storm water from three new catch basins to a tide gate structure at the southerly Pearl Avenue street end. A 15-inch-diameter storm drain pipe will be installed along the south Bayfront to convey storm water from the southerly Agate and Garnet Avenue street ends to the same tide gate structure. The 4-foot by 5-foot by 7-foot deep tide gate structure will be fitted with an electrically operated 24=inch tide gate, which will con- trol the flow of storm water into Newport Bay and the flow of high tide sea water into City streets. A 24-inch-diameter storm drain pipe will extend approximately 40 feet from the South Bayfront into Newport Bay. The bayward 20 feet of the pipe and the upper 2 feet of the tide gate structure will be visible above the public beach and above the South Bayfront sidewalk, respec- tively. All other physical features of the project will be subterranean. 3. PROJECT GOALS: The project will provide (1) relief from flooding in the inter- section of Park and Pearl Avenues, (2) relief from roadway generated splashing of private property and pedestrians near the intersection of Park and Pearl Avenues, (3) drainage capacity to replace deteriorated and inadequate drains located at the southerly street ends of Agate, Pearl and Garnet Avenues, and (4) a single, electrically operated tide gate to replace 3 manually operated, deteriorated tide gates at the aforementioned street ends. 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. 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. Copies of the Initial Study may be obtained from said department during normal business hours. Benjamin B. Nolan Public Works Director LRD:jd • • PEARL AVENUE STORM DRAIN INITIAL STUDY BY CITY OF NEWPORT BEACH PUBLIC WORKS DEPARTMENT A. 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) jas 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 catch basins and transmission pipe will increase the runoff rate and reduce the absorption rate correspondingly in the vicinity of the sump condition at Park and Pearl Avenues; however, the increased runoff rate will preclude the flooding of public and private property which has occurred heretofore 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 the improvements. II.18. Approximately 20 linear feet of the bayward end of the 24-inch- diameter storm drain pipe will be partially exposed along the South Bay Front. In addition, the tide gate structure will pro- ject approximately 2 feet above the sidewalk elevation at the southerly Pearl Avenue street end. 5/7/84 411 ENVIRONMENTAL CHECKLIST FORM Background 1.
