§ 18.80.070. ALUCP Zone A regulations.  


Latest version.
  • Within ALUCP Zone A, which is the runway protection zone, land uses are limited to open space, pasture, auto parking, aircraft tie-down, and agricultural uses which do not cause a hazard to flight. This is an area of high risk from low flying aircraft. The following standards shall apply in addition to the standards of the principal zoning district:

    A.

    Avigation easements in a form acceptable to the airport proprietor shall be required as a condition of subdivision approval and/or discretionary permits for new construction, and for any project requiring a building permit. Such easements shall be prepared prior to issuance of a building permit or recordation of a final map.

    B.

    Prohibited Uses. The following uses are prohibited:

    1.

    All Residential uses;

    2.

    Any assemblage of people;

    3.

    Any new structure exceeding county and/or FAA height limitations;

    4.

    Noise sensitive uses;

    C.

    Uses Not Normally Acceptable. The following uses raise concerns related to size, and hazards to flight to be addressed for a project to be approved. Such uses shall require use permits and shall be referred to the ALUC for a compatibility determination prior to final approval:

    1.

    Heavy poles;

    2.

    Signs;

    3.

    Trees;

    4.

    Lights;

    5.

    New ponds;

    6.

    Solar panels.

    D.

    Use Review Criteria. In determining whether proposed uses in subsection (C) of this section have been appropriately designed, the decision-making body shall consider the following criteria:

    1.

    Density. Total on site density for uses shall not exceed ten persons per acre. No permanent density is permitted within structures;

    2.

    Clustering. Clustering of development within the density parameters is encouraged to protect and provide open land/safety areas (such as requiring building envelopes, contiguous parking and landscape areas, and larger setbacks from certain geographic features such as creeks, roads, etc.);

    3.

    Noise. Applicable noise reduction measures have been incorporated for noise sensitive uses (such as hotels, motels and offices) consistent with ALUCP and county general plan standards;

    4.

    Location. Structures have been set back as far as possible from the extended centerline of the runway.

    E.

    General Design Requirements.

    1.

    Lights, Glare, Electronic Interference. All uses and structures shall be designed so as to prevent hazard to flight that could occur as a result of smoke, glare, distracting lights or electronic interference. All exterior lighting shall be directed or shielded to prevent glare to aircraft and meet any approved ALUC lighting guidelines.

    2.

    Height. All uses and structures shall be designed to prevent hazard to flight that could occur as a result of very tall structures intruding into flight areas. Height limits shall be as in the underlying zoning district, Napa County Airport Ordinance No. 416, and Federal Aviation Administration FAR Part 77 standards. Any project proposing heights over the applicable height limit shall require a use permit and be referred to the ALUC prior to final approval.
