§ 22.94.070. Nacimiento Sub-area Standards.

All development and new land uses in the Nacimiento Sub-area, as shown on Figure 94-5, shall comply with the following standards, where applicable.

A.

Finished floor elevations. Within the Lake Nacimiento watershed, the first floor of a building used for habitation shall not be constructed below the 825-foot elevation, except that habitable structures destroyed in the 2016 Chimney Fire may be reconstructed upon prior authorization by the Monterey County Water Resources Agency and issuance of a construction permit. Reconstruction shall be limited to the footprint and height of the destroyed structure.

B.

Water treatment. Where use of lake water is authorized by the County, the treatment of lake water shall include storage, coagulation, sedimentation, filtration, and chlorination. Intake systems shall be protected to prevent contamination either by means of a closed zone or other approved method. The systems shall be designed by a registered civil engineer and approved by the County Health Department.

C.

Sewage disposal.

1.

Individual sewage disposal systems. Individual sewage disposal systems are not permitted:

a.

On lots with an area less than 2½ acres per dwelling unit, except where a parcel is located within a cluster subdivision in compliance with Section 22.22.140 with a maximum density of 2½ acres or more per dwelling unit;

b.

Below an elevation of 825 feet above mean sea level (MSL);

c.

In any case closer than 200 feet, horizontal projection, from the lake's high water elevation of 800 feet;

d.

On slopes of 30 percent or greater; or

e.

Where percolation rates are less than one inch in 30 minutes.

2.

Substandard sewage disposal systems. Substandard sewage disposal systems that do not meet the requirements of the building code or the Regional Water Quality Control Board shall be replaced in conjunction with any new development.

D.

Circulation - New land divisions and Conditional Use Permit Plan projects.

1.

Proposals shall be integrated into areawide circulation and utility easements, providing for future extensions into adjacent undeveloped properties wherever feasible or where known areawide rights-of-way are planned.

2.

Road alignments shall be designed and constructed to minimize terrain disturbance consistent with safety and construction cost. Altered slopes shall be replanted with indigenous plants where practical or protected by other appropriate erosion control measures.

3.

New projects shall include an offer of dedication for interior and abutting roads where needed for public access and circulation. Until these roads are accepted for public use, maintenance shall remain the responsibility of the involved property owners.

4.

New developments shall include, where possible, design provisions for combining driveways and private access roads serving proposed parcels wherever terrain and adequate sight distance on the public road allow.

5.

New developments shall provide for safe and site-sensitive pedestrian and bike circulation facilities in the design of roads where feasible.

E.

Density calculations - Usable area. In the Lake Nacimiento watershed only land above the 800-foot elevation shall be used when computing density or minimum building site area.

F.

Easterly of the Santa Lucia Range. The following standards apply only to the area east of the Santa Lucia Range corresponding to the pre-1990 boundaries of the Nacimiento Planning Area as shown in Figure 94-29.

Figure 94-29: Pre-1990 Nacimiento Planning Area Boundaries

1.

Open space preservation. Approval of an application for land division, Site Plan, Minor Use Permit, or Conditional Use Permit is contingent upon the applicant executing an agreement with the County to maintain portions of the site not intended for development in open space use. Guarantees of open space preservation may be in the form of agreements, easements, contracts or other appropriate instrument, provided that such guarantees are not to grant public access unless desired by the property owner.

2.

RV parks - Location criteria. Proposed recreational vehicle parks shall be located within one mile of a road improved to County standards.

3.

Public recreation. Future public campgrounds or picnic areas shall be designed and located in compliance with the densities and location specified in Figure B.1-1 and Table B.1-2 in Appendix B of the Area Plans.

4.

Sloping Sites. Conditional Use Permit proposals for sites with varied terrain shall include design provisions for concentrating developments on moderate (less than 20 percent) slopes, retaining steeper (20 percent or greater) slopes that are visible from public roads undeveloped where practical except that outside of the pre-1990 planning area boundaries as shown in Figure 94-28, steeper slopes that are visible from public roads shall be kept undeveloped.

G.

Utility services - Undergrounding with Conditional Use Permit projects. All projects requiring Conditional Use Permit approval (including commercial and residential uses fronting the shoreline) shall provide for utilities being placed underground unless the Commission determines either that: the proposed development will be of low intensity or in an isolated location; or that supporting overhead utilities will not be visible from public roads; or that overriding operational, economic or site conditions of the project warrant waiver of this requirement.

H.

Site selection criteria. New development shall be located to not be visible from Highway 1, as follows:

1.

Sites shall be selected where hills and slopes would shield development, unless no alternative location exists or the new development provides visitor-serving facilities; and

2.

New development shall be located so that no portion extends above the highest horizon line of ridgelines as seen from Highway 1.
