A. The construction or placement of any improvement which may significantly affect the natural erosion process resultant from the interaction of water bodies upon their shores, or cause significant adverse alteration of the bay or ocean environment shall require a coastal permit from the City. Without limitation, buildings, harbor channels, breakwaters, groins, piers, retaining walls, revetments, riprap, sea walls and similar items shall be governed by this chapter.
B. An improvement or activity requiring a coastal permit under this chapter shall only be allowed when it serves coastal dependent uses, protects existing structures, removes public hazards, or protects public beaches in danger of erosion.
C. In order for an improvement or activity requiring a coastal permit under this chapter to qualify for such a permit, the improvement or activity must be designed and constructed as follows:
1. To neither create nor contribute significantly to erosion or geologic instability;
2. To minimize their own breakdown and disintegration;
3. To minimize water pollution and the silting of coastal waterways;
4. To not result in a substantial or potentially substantial, adverse change in any of the physical conditions within the area affected by the coastal permit requiring activity including land, air, water, minerals, flora, fauna, ambient noises and objects of historic or aesthetic significance;
5. To not preclude the public’s right of access to (including without limitation) the ocean, bay or public beach where acquired through use, custom, legislative authorization, purchase, condemnation, judicial action, gift, bequeath or escheat;
6. To encourage or facilitate, where feasible, the phasing out or upgrading of marine structures causing water stagnation contributing to pollution problems or fish kills;
7. To minimize their intrusion into public vistas by being unobtrusive and aesthetically pleasing when viewed from public streets, walk or bicycle ways or waterways;
8. To minimize extensions or projections into the bay or ocean;
9. To facilitate public access where appropriate and feasible; and
10. To minimize or mitigate resultant adverse environmental impacts.
D. The applicant, at the determination of the Coastal Permit Administrator, shall provide a certification by a civil engineer acceptable to the City indicating that the proposed improvement or activity conforms to the above criteria. (Ord. 1533)
For waterfront land recorded on Miscellaneous Map 121 (Rancho Peninsula), Record of Survey 563, 2372, and Map 2544 (Bay View Estates), Record of Surveys 5191, 6014 and 6958, retaining walls, revetments, riprap, sea walls and similar development shall be permitted, with a coastal permit, subject to all other standards of this chapter, with the provision that such improvements may be situated in a manner so that the improvements’ bayward faces may connect in a straight line the bayward faces of similar improvements on adjoining property.
