(c)

Development standards. The following standards apply to all new development along the shoreline and on coastal bluffs.

(1)

Alteration of the shoreline, including diking, dredging, filling and placement or erection of a shoreline protection device, shall not be permitted unless the device has been designed to eliminate or mitigate adverse impacts on local shoreline sand supply and it is necessary to protect existing development or to serve coastal-dependent uses or public beaches in danger from erosion or unless, without such measures, the property at issue will be rendered undevelopable for any economically viable use;

(2)

Consistent with the City's Seismic Safety and Safety Element, new development which requires sea-walls as a mitigation measure or projects which would eventually require seawalls for the safety of the structures shall be prohibited, unless without such seawall the property will be rendered undevelopable for any economically viable use;

(3)

Required shoreline protection devices shall be designed and sited to consider and reflect:

(i)

Maximum expected wave height,

(ii)

Estimated frequency of overtopping,

(iii)

Normal and maximum tidal ranges,

(iv)

Projected erosion rates with and without a shoreline protection device,

(v)

Impact on adjoining properties,

(8)

The seawall shall be designed to minimize impacts upon existing lateral and vertical access and in any case shall not result in the blocking of an accessway. In cases where it is not possible to engineer a wall without blocking access, then appropriate mitigation measures shall be incorporated into the design. These measures can include a stairway over the seawall to provide continuous vertical access or a platform over the seawall to provide continuous lateral access.

(§ VI, Ord. 610-C.S., eff. March 16, 1994)

(a)

Intent. The provisions of this section shall apply to all new development requiring a coastal development permit in the CZ District and where public shoreline access is required in the Access Component of the LCP Land Use Plan, and shall be subject to the regulations found in Article 43, Coastal Zone Combining District. The intent of these provisions is to maximize public access to and along the shoreline, while protecting the established rights of private property owners.

(b)

Development standards. The following development standards shall apply to all required access provisions.

(1)

To provide separation between shoreline access and residential uses and to protect the privacy and security of residents and homes, any required access easements shall comply with the following setbacks, where feasible:

(i)

The inland edge of lateral shoreline trails shall be at least twenty-five (25′) feet from any occupied or proposed residence. However, in the event a twenty-five (25) foot access buffer will not provide adequate lateral public access in compliance with the access provisions of the Coastal Act or with the Access Component of the LCP Land Use Plan, a narrower access buffer may be required. In no event shall the lateral accessway extend any closer than ten (10′) feet from the residence in question; and

(ii)

The edge of vertical shoreline trails shall be at least ten (10′) feet from any existing or proposed residence.

(2)

Public shoreline access through environmentally sensitive habitat areas shall comply with the provisions established in Section 9-4.4403, Habitat Preservation and the California Coastal Act, Section 30212;

(4)

Public shoreline access improvements such as trails, stairs, ramps, railings, viewing areas, restrooms, and parking facilities shall be sited and designed to be compatible with the natural character of the shoreline;

(5)

Public shoreline access signage shall identify access location, destination areas, environmentally sensitive habitat, and hazardous conditions, and be compatible with the natural appearance and character of the shoreline by using appropriate color, size, form and material; and

(6)

Any required vertical trail easement shall be at least ten (10′) feet wide. Any required lateral access easement shall be at least twenty-five (25′) feet wide. However, in the event such an easement width would prohibit private use of the real property or render use or development of the site economically infeasible, a narrower access width may be required. In no event shall the lateral access width be less than ten (10′) feet.

(7)

With respect to lateral bluff top access, the easement shall be adjusted inland from the current bluff edge if it recedes inland, but in no event shall the trail be closer than ten (10′) feet to an occupied or proposed residence. Such an inland adjustment shall not occur in the event it would prohibit private use of a site or would render use or development of the site economically infeasible.

(1)

Applicable standards as set forth in Articles 10 and 11 of this chapter;

(2)

If the proposed visitor-serving commercial use will result in a mix of commercial uses that is not consistent with the provisions of the LCP Land Use Plan, such use may be conditionally permitted, subject to the following criteria:

(i)

The addition of the proposed use will not significantly alter the overall character of the small-scale, residentially oriented features of the neighborhood;

(ii)

The proposed use will not by itself serve to convert the predominant character of the area; and

(iii)

The proposed use will not present a barrier to the efficient functioning of the area as a neighborhood-serving shopping district.
