500.06: REGULATIONS FOR SAFETY: — Porterville Zoning Code

A. Development Standards: Table 500.06A of this section describes the development standards for all development within the airport safety zones as shown in section 500.10, map 500-2, "Airport Impact Map: Safety", of this article. Additional standards follow the table.

TABLE 500.06A: DEVELOPMENT STANDARDS -AIRPORT SAFETY ZONES

Standard	Standard			Safety Zones	Safety Zones
		1	2	3	4	5	6

Standard				Safety Zones
		1	2	3	4	5	6
Maximum lot coverage (% of site)		0	40	60	70	70	100
Nonresidential development:
	Maximum sitewide average intensity (people/acre)	10	60	100	160	160	n/a
	Maximum single acre intensity (people/acre)	20	120	250	400	400	n/a
Residential development:
	Maximum sitewide average density (units/acre)	n/a	n/a	4	4	n/a	n/a
	Maximum single acre density (units/acre)	n/a	n/a	12	12	n/a	n/a

1. Intensity Calculation:

a. Nonresidential Development: Usage intensity calculations shall include all people (e.g., employees, customers/visitors) who may be on the property at any single point in time, whether indoors or outdoors. The city may make exceptions for rare special events (e.g., an airshow at the airport) for which a facility is not designed and normally not used and for which extra safety precautions can be taken as appropriate.

b. Residential Development:

(1) The maximum allowable residential densities are intended to include density bonuses and any other bonuses or allowances that the city may provide for affordable housing developed in accordance with the provisions of state and/or local law or regulation. The overall density of a development project, including any bonuses or allowances, must comply with the allowable density criteria in table 500.06A of this section.

(2) Second units are excluded from density calculations.

c. Mixed Use Development:

(1) Where the residential and nonresidential uses are proposed to be situated on separate parts of the project site, the project shall be evaluated as separate developments. The residential density shall be calculated with respect to the area(s) to be devoted to residential development and the nonresidential intensity calculated with respect to the area(s) proposed for nonresidential uses.

(2) Development in which residential uses are proposed to be located in conjunction with nonresidential uses in the same or nearby buildings on the same site must meet both residential density and nonresidential intensity criteria. The number of dwelling units shall not exceed the density limits indicated in table 500.06A of this section. Additionally, the normal occupancy of the residential portion shall be added to that of the nonresidential portion and the total occupancy shall be evaluated with respect to the nonresidential usage intensity criteria cited in table 500.06A of this section.

B. Airport Safety; Compatibility Criteria: In regard to airport safety, land uses are classified as being either "normally compatible", "conditional" or "incompatible" as defined below.

Normally compatible: Normal examples of the use are compatible under the presumption that usage intensity and maximum lot coverage criteria in table 500.06A of this section will be met. Atypical examples may require review to ensure compliance with usage intensity and lot coverage criteria. Noise, airspace protection, and/or overflight limitations may apply.
Conditional: Use is compatible if indicated floor area ratio (FAR), lot coverage, and other listed conditions are met.
Incompatible: Use shall not be permitted under any circumstances.

C. Airport Safety; Land Use Compatibility: Table 500.06C of this section describes the compatibility of various land uses

within the airport safety zones as shown in section 500.10, map 500-2, "Airport Impact Map: Safety", of this article. Land uses are classified as being either "normally compatible", "conditional" or "incompatible".

Land uses not specifically listed in table 500.06C of this section shall be evaluated by the zoning administrator based on the criteria for the most similar comparable use.

Numbers in table cells refer to the maximum allowable FAR.

Notes in table cells refer to criteria to be met by uses listed as "conditional". The note numbers refer to criteria listed at the end of the table.
