Location: The proposed project is located in the City of Newport Beach adjacent to the Newport Pier on the Peninsula. An exhibit is attached showing the location of the project. 2. Project Description: The project proposes constructing wood extensions on the seaward end of the four existing wood groins adjacent to the Newport Pier. Three of the extensions will be 24 feet long, the fourth 48 feet long; all terminate at the same shore line. A parallel protection system between the groins will consist of a sacked concrete slope revetment. 3. Purpose of Project: The purpose of the project is to provide interim protection to the existing City Lifeguard Headquarters building and the Dory Fishing Fleet shore establishment. The recent erosion of the beach berm has undermined the building, necessitating emergency repairs and protective measures. It is antici- pated that permanent protection will be provided by an extension of the existing. Corps of Engineers beach erosion control project. 4. Discussion of Environmental Impacts The proposed project is consistent with the City's General Plan policies, requires no additional right-of-way, and will not cause the relocation of any people or the disturbance of any buildings. The possibility of tidal flooding landward of the project should be reduced, and the quality of the ocean water will not be affected. There will be no additional noise or pollution as a result of this project. The magnitude and dimensions of the project are such that the over-all beach regime will not be affected. Only 140 feet of the 27,000 feet of the beach compartment extending from the Santa Ana River to the Newport Harbor entrance is affected. The 24 and 48 foot lengths of the groin extensions are insignificant compared to the beach width and the 340 to 600 foot lengths of the existing rubble mound groins installed by the Corps of Engineers in the years 1968-1973. The sandy beach below the proposed groin extensions will be disturbed temporarily during placement of the piles. This disturbance should not have a significant effect on the marine organisms, since the area was beyond the surf zone (inhabited by biota) until the recent degradation of the beach berm. There will be no long-term, irreversible or irretrievable effects on the environ- ment, and no significant short-term effects. Temporary impacts during and imme- diately subsequent to construction of the project will not be to the disadvantage of long-term environmental goals of protecting and preserving the invaluable sandy beach coastline. Environmental Impaclitatement - Negative Declaration Extension of Wood Groins at Lifeguard Headquarters Page 2. 5. Basis for Negative Declaration The proposed project has been reviewed in conjunction with Sections 15081, 15082, and 15083 of the "Guidelines for Implementation of the California Environmental Quality Act of 1970". Criteria set forth in these sections indicate that the project will not have a significant environmental impact. • "'FACT'SHEET • 'TO DETERMINE " IF'PROJECT HAS SIGNIFICANT ENVIRONMENTAL EFFECT EXTENSION OF WOOD GROINS AT LIFEGUARD HEADQUARTERS A. Conformance with City's Goals This project conforms to the City's objective "to ensure the protection and enhance- ment of the harbor and ocean waters, their adjoining beaches and shoreline" and the supporting policy of preserving "the ocean beaches...and coastal shoreline in a manner that will ensure their -availability for continued public use and enjoyment". The groin extensions will provide protection for the Lifeguard Headquarters and the Dory Fishing Fleet and will help to replenish the beach area that has been lost recently by unusually severe tidal erosion. B. Land Use Existing land use surrounding the proposed project is public beach, with the Newport Pier and the City's Lifeguard Headquarters adjacent. The project involves land restoration rather than any loss of land or change in use. No right-of-way will be required to construct the proposed project. C. Human Resources The project will provide a buffer of protection against the undermining of the existing Lifeguard Headquarters building and the further loss of beach area used by the Dory Fishermen. The anticipated accretion will restore the beach width for public use and enjoyment, and stabilize the existing and restored beaches. The project will not require the relocation of any people. D. Geologic Hazards Liquefaction and erosion are potential hazards in the project area. The construc- tion of the wood groin extensions and the revetment will not affect the damage potential of liquefaction, nor will liquefaction affect the design or construction of the groins. The project should reverse the continual degrading effects of surf erosion and littoral drift in the immediate area. E. Flooding and Water Quality The expected build-up of the beach within the area of the groin extensions should diminish the possibility of tidal flooding landward of the shoreline. No pollution is anticipated as a result of the project or contractor's operations. F. Noise Level After construction is completed, the project will neither increase nor decrease the noise level in the area. G. Air Resources The project will not affect air quality. Fact Sheet Extension of Wood Groins -at Lifeguard Headquarters Page 2. H. Vegetation and Animal Life The construction of the groin extensions and revetment will temporarily disrupt any existing sandy beach biota. However, due to the severe recent erosion, the area in which the groins are to be built was until recently beyond the intertidal zone, where the majority of the biotic community dwells. In any event, disturbance will be limited to the small area occupied by the narrow groins. Marine organisms which now exist in the surf zone should adjust to the gradual accretion expected to result from the presence of the groins, since this is normally a natural occur- rence. I. Natural Resources The sandy beach shoreline is one of the most valuable natural resources of Southern California. Preservation of this coastline for recreational purposes, as well as protection of backshore properties and structures from damage which may result from further erosion of the beach berm, is a desirable goal. Beach sand, an important natural resource, is becoming increasingly difficult to replace, due to the reduc- tion in sediment deposits at the mouths of the tributary drainage areas near the project area. The groin extensions should result in the replenishment of the beach area and the stabilization of the shoreline near the Newport Pier. J. Long Term Impacts This project will have no adverse long-term effects on the commitments of resources in the City. The project should result in the restoration and protection of the valuable beach berm near the Newport Pier, minimizing the potential of further damage to the adjacent structures. The relative insignificance of this project becomes apparent when it is related to the existing conditions of the beach from the Newport -Harbor entrance to the Santa Ana River. The project affects only 140 feet of the 27,000 feet of beach. The groin extensions, measuring 24 feet (3) and 48 feet (1) in length, are minor com- pared to the eight rubble mound groins built by the U.S. Army Corps of Engineers northerly of the Newport Pier from 1968 to 1973. These groins measure from 340 feet to 600 feet in length. The effects of the project are localized and will not significantly influence the over-all beach regime. K. Short Term Impacts Anticipated short-term impacts include noise and restricted access during construc- tion, temporary disturbance of the sandy beach during pile installation, and the presence of the wood groins on the wet slope until the expected resulting accretion covers them with sand. These impacts are not considered to have a significant effect on the environment. L. Summary The project does not appear to have any significant adverse environmental effects. In fact, the decision not to construct the groin extensions could result in con- tinued severe erosion with loss of additional sandy beach width, and eventually damage to valuable real estate on and adjacent to the beach.
