(c)
Submittal of Plans. Development plans shall be submitted to the director at least ten (10) days prior to application for those permits required by Section 18500 of the Health and Safety Code or its successors, and any other pertinent permit requirements of the county and the Department of Housing and Community Development of the state.

(Ord. No. 1928.)
(d)
Expansion and Staged Development. Development may be in stages so long as each stage meets the minimum standards of this section.
(e)
Density. The maximum permitted residential density for a mobile home park shall be one hundred thirty-five percent (135%) of the density established on the zoning map.
(f)
Park Area. No mobile home park shall be less than three (3) acres in area within the R1 Low Density Residential Zone District, or less than two (2) acres in area within the R2 Medium Density Residential and R3 High Density Residential Zones.
(g)
Setbacks. All structures and mobile homes shall maintain setbacks from the exterior property lines of the mobile home park in accordance with the regulations of the applicable zoning district; provided, however, that a setback of at least twenty feet (20′) shall be maintained from all exterior public roadways, so as to allow for fencing and landscaping in accordance with subsection (p) of this section.
(h)
Parking. Mobile home parks shall provide parking pursuant to Article 86, Parking. At least one (1) guest parking space shall be provided within a designated guest parking bay for every three (3) mobile homes. Guest parking shall be dispersed in parking bays throughout the development, and shall be in addition to the parking requirement which may be made for a community or recreational building commonly open to visitors. Where the interior streets of a mobile home park do not allow for parking on both sides, scattered parking bays of a minimum nine feet (9′) depth and containing from three (3) to five (5) visitor parking spaces are required to meet fire safe accessibility standards.
(i)
Recreational Space. Each mobile home park shall provide recreational space in accordance with applicable zoning district regulations for residential developments of similar size. Such recreation space may be provided as outdoor or indoor space, and may include such facilities as community swimming pools and other active recreational facilities, common landscaped and accessible walkways, developed recreational trails, parcourses, play areas and picnic areas, and indoor community gathering facilities. In no case shall credit toward the required minimum recreational area be granted for roadways, fire lanes, or parking areas. Recreation space design and location shall be approved by the director.
(j)
Utilities. All utility distribution facilities, including but not limited to electric, communication and cable television lines, installed in and for the purpose of supplying service to any mobile home park shall be placed underground, except as follows: equipment appurtenant to underground facilities, such as surface-mounted transformers, pedestal-mounted terminal boxes and meter cabinets and concealed ducts. The developer is responsible for complying with the requirements of this subsection and shall make the necessary arrangements with the utility companies involved for the installation of such facilities.
(k)
Storage Facilities and Garbage Collection. A minimum three-foot (3′) by five-foot (5′) by five-foot (5′) cabinet for storage shall be provided within the rear yard, or within the rear half of a side yard, on each site. Adequate trash enclosures and facilities for park residents which allow for the source separation and collection of household recycling and garbage collection shall be provided to the satisfaction of the director.
(l)
Accessory Uses. Accessory uses are those uses that are incidental to the original use, exist for the sole purpose of service to residents, are customarily found in multiple-family development, and do not alter the character of the original use. Any structure used for an accessory use shall meet all requirements for a main structure. Allowable accessory uses include vending machines, a common car wash, storage area for travel trailers and boats, a management facility, recreational facility, and other uses which in the opinion of the director are of a similar nature.
(m)
Occupancy of Recreational Vehicles (Travel Trailers). In the R2 or R3 zoning districts, and where allowed by the HCD license and the use permit, short-term overnight use of recreational vehicles may be permitted where adequate sewer and water hook-ups, parking capacity, and compliance with all applicable health and safety and building codes can be shown. In each case, such proposed use shall be included in the application for use permit so that compatibility may be reviewed. All such recreational vehicle spaces shall be designated on the development plan and shall be separated from permanent mobile home spaces. Overnight use of recreational vehicles or travel trailers in mobile home parks located within the R1 or PC zoning districts is prohibited.
(n)
Storage of RVs, Boats, Recreational Vehicles and Travel Trailers. In the R2 or R3 zoning districts, the storage of RVs, boats and travel trailers owned by permanent park residents may be permitted with a use permit. Any areas proposed for the storage of recreational vehicles (RVs, boats, and/or travel trailers) owned by permanent park residents shall be shown on the development plan. The storage area shall be fully screened, shall have no public access, shall allow only limited access by park residents, and shall be fenced and otherwise secured at all times.
(o)
Walls, Fences, etc. A six-foot (6′) wall, fence or landscape screen may be required along all perimeter boundaries of the mobile home park. The decision making body shall make a determination on the requirement for this fence on the basis of aesthetics and compatibility with surrounding proposed and existing development. Where a screening wall is required along a public street, it shall be placed fifteen feet (15′) from the public right of way, in order to allow buffer landscaping to be placed outside of the fence and adjacent to the public street. Such wall or fence, if required, shall not be less than forty-two inches (42″) in height nor greater than six feet (6′) in height.
(p)
Landscaping. All open or common areas, excluding mobile home sites, shall be landscaped and maintained. At least forty percent (40%) of all the open or common areas shall be landscaped with live materials. Landscaping shall include planting of trees of a five (5) gallon size along all perimeter boundaries of the mobile home park, at a minimum planting rate of one (1) tree per mobile home site. Additional trees and more mature trees may be required where they are being utilized for screening, or in lieu of fencing development. Plans shall indicate the means of irrigation for all landscaped areas, including perimeter areas where trees or other screening landscape are provided.
(q)
Signs. One non-illuminated or indirectly illuminated detached appurtenant sign not exceeding ten feet (10′) in overall height or thirty-two (32) square feet in area shall be permitted for each mobile home park, and shall be integrated into the landscape with the location and elevation approved by the director.
(r)
Access. All entry streets shall be paved to a minimum of twenty-five feet (25′), and no parking shall be allowed within fifty feet (50′) of the intersection. All interior park streets shall be paved to a width of not less than twenty-two feet (22′) from shoulder to shoulder where no on-street parking is allowed. Interior streets shall be thirty-three feet (33′) in width if car parking is permitted on one (1) side, and forty-one feet (41′) in width if car parking is permitted on both sides.
(1)
No park entry road shall be located closer than one hundred feet (100′) to any public intersection unless authorized by the director of transportation and public works.
(2)
A "looped" system of narrower interior roadways is encouraged in lieu of cul-de-sac streets. Where they are allowed, cul-de-sac streets shall have a minimum outside turning radius of thirty-eight feet (38′).
(3)
All interior corners shall have a minimum fifteen-foot (15′) radii unless a reduced dimension is authorized by the director or the decision maker.
(4)
Curbs and gutters shall be installed on both sides of entry and access roads. The planning commission may approve alternate treatment for vehicular, pedestrian and bicycle circulation where appropriate in cases of extreme topography or low-density developments.
(5)
All streets shall be adequately lighted. The placement, style and height of all street lighting shall be subject to design review and shall generally not exceed a height of twelve feet (12′) along interior streets or sixteen feet (16′) along the park entry road so as to avoid lighting glare and spill-over into adjoining properties. Any taller light standards used, including any "cobra-head" fixtures as may be required along abutting streets, shall incorporate full cut-off shields to eliminate lighting glare and spill-over into the night sky and onto adjoining properties.
(6)
Each site shall front on an access street. Alternatively, where mobile home sites are provided in clusters, no more than four (4) such clustered sites shall share a common frontage on an access street with a minimum ingress/egress width of twenty-four feet (24′).
(7)
Stop signs shall be provided at all intersections with all public streets.
(s)
Circulation. Proximity to public transit and alternative transportation modality shall be encouraged and accommodated. All mobile home park developments shall complement adjoining, existing or contemplated vehicle, transit and pedestrian/bicycle circulation patterns. All mobile home park developments shall dedicate such land adjoining public roads as may be required by the county for road widening purposes and improvements of the same to county standards may be required, as stipulated by the director of transportation and public works, to offset the burden placed on the public by the generation of new traffic.
(t)
Compliance with State Regulations and Other Regulations of the County. All pertinent state and county regulations concerning the development and operation of mobile home parks shall be observed. Nothing contained in this section shall be construed to abrogate, void or minimize such other pertinent regulations.
