10-5-23: AO AIRPORT OVERLAY ZONE:
   (A)   Purpose: The purpose of this zone is to:
      1.   Implement the Placerville Airport land use compatibility plan (ALUCP) in accordance with state law, adopted by the El Dorado County airport land use commission (ALUC) and incorporated into the general plan land use element by city council resolution 8105;
      2.   Implement the city's general plan policy to provide for land uses surrounding the Placerville Airport that is consistent with the Placerville ALUCP;
      3.   Protect land uses around the airport from potential hazards of airport operations;
      4.   Identify a range of uses compatible with airport accident hazard and airport noise exposure;
      5.   Prohibit the development of incompatible uses that are detrimental to the general health, safety and welfare and to existing and future airport operations;
      6.   Require noise attenuated construction within the airport environs; and
      7.   Comply with federal aviation administration (FAA) regulations.
   (B)   Applicability: The standards and regulations of this section apply to all lands within the AO overlay zone mapped on the official zoning map. The AO overlay zone is conterminous with the Placerville Airport influence area as identified in the adopted ALUCP influence area map in chapter 6 and defined under section 2.7 of chapter 2 of the ALUCP.
Regulations in the AO overlay zone modify and supplement the underlying zoning designation regulations. Within the AO overlay zone district, the noise impact zones, airport safety zones, airspace protection and aircraft overflight zone policies of the ALUCP apply.
   (C)   Permitted Uses: All of the uses permitted in the underlying zone, provided the use is consistent with the land use compatibility policies and criteria with respect to airport related noise, public safety, airspace protection, and aircraft overflight areas established in the ALUCP.
   (D)   Development Review Procedures: The Placerville ALUCP in effect at the time an application was deemed complete shall be the basis for compatibility review.
      1.   Development Services Department Review:
         (a)   New development or expansion of existing development within this overlay zone shall be subject to review by the development services director, or designee for ALUCP consistency. Depending on the type of land use development, a consistency review could also involve action by the planning commission and possibly city council as part of other land use requests authorized within this title. Examples of other land use requests include, but are not limited to, site plan reviews, tentative subdivision maps, general plan amendments, zone changes, variances, conditional use permits, etc.
Proposed land uses within the zone shall be consistent with the following compatibility policies and maps in chapters 4 and 6 of the Placerville ALUCP:
            (1)   Noise compatibility policies: Subsections 4.2.1 through 4.2.4 of section 4.2, the noise compatibility criteria in table 1 of chapter 4, and the noise zones policy map of chapter 6;
            (2)   Safety compatibility policies: Subsections 4.3.1 through 4.3.8 of section 4.3, the safety compatibility criteria in table 2 of chapter 4, and the safety zones policy map of chapter 6;
            (3)   Airspace protection policies: Subsections 4.4.1 through 4.4.5 of section 4.4 of chapter 4 and the airspace protection zones policy map of chapter 6;
            (4)   Overflight policies: Subsections 4.5.1 through 4.5.3 of section 4.5 of chapter 4 and the overflight zones policy map of chapter 6;
            (5)   Special circumstances policies: Section 4.6 of chapter 4;
            (6)   Additional compatibility policies: PLA.1 of chapter 6.
         (b)   Minimum submittal requirements for development review:
            (1)   Property location data (assessor's parcel number, street address, subdivision name, lot number).
            (2)   An accurately scaled map depicting the project site location in relationship to the airport boundary and runways.
            (3)   A description of the proposed use(s), current general plan and zoning designations, and the type of land use action being sought from the city (e.g., zoning variance, conditional use permit, site plan review, building permit).
            (4)   When determined by the development services director or designee, a detailed site plan and supporting data showing: site boundaries and size; existing uses that will remain; location of existing and proposed structures, open spaces, and water bodies; ground elevations (above mean sea level) and elevations of tops of structures and trees. Additionally:
               A.   For residential uses, an indication of the potential or proposed number of dwelling units per acre (excluding any secondary units).
               B.   For nonresidential uses, the total floor area for each type of proposed use, the number of auto parking spaces, and, if known, the number of people expected to occupy the total site or portions thereof at any one time during busiest periods.
            (5)   Identification of features, during or following construction, that would increase the attraction of birds or cause other wildlife hazards to aircraft operations on the airport or in its environs (see policy 4.4.3(a)(6)). Such features include, but are not limited to, the following:
               A.   Open water areas.
               B.   Sediment ponds, retention basins.
               C.   Detention basins that hold water for more than forty eight (48) hours.
