Conformance with City Goals The project is in conformance with the City's long-term goal to replace any existing deteriorated water and sewer mains which have become a maintenance problem, or no longer serve their purpose because of poor condition. B. Land Use Existing land use adjacent to the proposed project is residential. The project will be constructed within the existing public right-of-way, requiring no addi- tional right-of-way, and is essentially a replacement project. C. Human Resources The project does not affect any existing building or require the relocation of any people. D. Geologic Hazards Liquefaction is a potential hazard in the project area. However, construction of the new water and sewer mains will not affect the damage potential of this hazard, nor will liquefaction affect the design or construction of the new mains E. Water The construction of this project will not change the currents or the direction of water movements in the canal. The project will not affect the water -related hazards to the residents adjacent to the Canal. The water quality in the bay will not be changed as a result of this construc- tion. The construction will be conducted in a manner to preserve the existing water quality. If dewatering becomes necessary, a permit will be obtained from the Sanitation Districts of Orange County to allow discharge of the effluent into the nearby sewer system. F. Canal Dredging Dredging to prepare a trench for installing be minimal --approximately 300 cubic yards. arily stock -piled for later use as backfill cause the bed of the canal along the trench ever, the bed of the canal will be returned tractor. the new water and sewer mains will The dredged material will be tempor- for the trenches.

Erosion and Siltation The project specifications and special provisions will require the contractor to employ erosion control measures during construction to minimize the possibility of siltation. H. Noise Level During construction, noise levels may rise due to operations which are necessary to construct the project; however, these operations will be limited to normal working hours to ensure a minimum of disturbance'to neighboring residents and commercial establishments. The operations will cease upon project completion. I. Air Resources This project will not affect the ambient air quality of this region or create any objectionable odors. J. Recreation The quality and quantity of recreational use of the canal by the community will not be affected by this project. However, there will be some inconveniences to boat owners and those wishing to sail during the construction period. These inconveniences will end upon completion of the project. K. Archeological and Paleontological Sites There are no known archeological or paleontological sites within the project limits. However, should dredging operations encounter significant fossils or artifacts, construction scheduling will be altered in line with Council Policy to allow sufficient time for investigation and recovery of finds. L. Vegetation and Animal Life There are no known rare or endangered species or habitats of such speciesof animal or plant life within or adjacent to the project area. All vegetation removed to facilitate construction will be replaced in kind under the construc- tion contract. M. Secondary Consequences It has been determined that no secondary consequences will arise from the minor primary consequences associated with this project. N. Long -Term Impacts This project will have no long-term, irreversible or irretrievable effects on the commitment of resources in the City. 0. Short -Term Impacts The only short-term impacts anticipated are those associated with most construc- tion projects of this type. They are such items as noise and some inconvenience • Fact Sheet C-1959 Page 3 to the residents adjacent to the project. These impacts are not considered to have a significant effect on the environment. P. Summary The project does not appear to have a significant effect on the environment. In fact, it would seem that the decision not to construct the project would have a more important effect on environment, as failure of the existing mains to function properly may affect public health and safety. u• DUNES \ • \ amfr f r IS Ate`, / 10 _rc b' r) <a;� U m Ca, a''-'1 n n' 7 JULIO f lJ n Liu _Nt-k , • 0,00 ) •' 4 Q o �a oL g�`o € a h 0 h V 5415Oa PIER • of e,yaa -1 C- pUBLUC • 0 i CITY OF NEWPORT BEACH PUBLIC WORKS DEPARTMENT DRAWN E D.
