In addition to the declaration of legislative intent set forth in § 145-2 of this chapter, it is hereby declared to be the specific intent of this article with respect to mobile home development to establish standards of performance and promote the desirable benefits which planned mobile home developments may have upon the community and the residents within them. It is further the intent of this article to ensure the interdependency and compatibility of proposed mobile home developments with essential utilities and surrounding land uses in the Township. It shall further be the intent of this article:
A.
To reflect the changes in the technology of home building
and land development so that resulting economies may inure to the
benefit of those who need homes.
B.
To further the general welfare by extending greater
opportunities for better and more affordable housing to all present
and prospective residents of Franconia Township.
C.
To provide for better quality and greater variety
in type, design and layout of mobile home developments than has been
evident in many mobile home parks in the past by enforcing uniform
standards, desirable design criteria and encouraging innovative site
design approaches.
D.
To provide for a diversity in housing types and prices.
E.
To encourage mobile home developments that are beneficial
rather than detrimental to property values and the general welfare
of the area in which they are proposed.
Mobile home developments are allowed only as a conditional use in the R-50 Residential District, provided that the tract to be used as a mobile home development meets the criteria specified in § 145-48 of this article. The uses which are permissible in a mobile home development are as follows:
A.
Residential uses. A mobile home development may include
mobile homes of single width or multiple width, or both, single-family
detached modular homes, conventionally built single-family detached
homes (including zero-lot-line homes) or any combination thereof,
but shall not include travel trailers or motor homes. No more than
40% of the total number of dwelling units in a mobile home development
may be conventionally built.
[Amended 10-9-1990 by Ord. No. 175]
B.
Nothing in this article shall be deemed as prohibiting
the rental, sale or resale of a mobile home located on a mobile home
stand and connected to the pertinent utilities. Similarly, a model
or display area is permissible on a temporary basis, provided that
those models are developed in accordance with all applicable regulations
of this article and other applicable ordinances, and use of the models
for sales or rental promotion ceases when the project is fully developed.

Editor's Note: Former § 145-47,
Approval procedure, was repealed 10-9-1990 by Ord. No. 172.
A mobile home development may be allowed by the Board of Supervisors as a conditional use in the R-50 Residential District only pursuant to the procedure specified in § 145-47[1]and subject to the following standards. The burden of proving
compliance with these standards shall be on the applicant.
A.
The tract of land to be developed shall be in one
ownership or shall be the subject of an application filed by the owners
of the entire tract, and it shall be agreed that the tract shall be
developed under single direction and in the manner approved.
B.
Any parcel to be used as a mobile home development
must have a minimum tract area of 15 contiguous acres of land.
C.
At least 50% of the site must be composed of developable
land, as defined in this chapter.
D.
Any site proposed for a mobile home development shall
not be subject to adverse environmental influence, such as swamps,
marshes, garbage or rubbish disposal areas or other potential breeding
places for insects or rodents.
E.
Any site proposed for a mobile home development shall
not be subject to any hazard or nuisance, such as excessive noise,
vibration, smoke, toxic matter, radiation, heat, odor or glare, as
defined by the governing body and all appropriate ordinances.
F.
The location of all mobile home developments shall
be protected by screening or other appropriate means against any undesirable
off-site views or any adverse influence, such as heavy commercial
or industrial use, heavy traffic or brightly lighted activities from
adjoining streets and areas.
G.
Mobile home developments shall not be located directly
abutting conventionally built single-family detached housing of significantly
different value and density than the proposed mobile homes, except
where extensive natural buffering exists and will be retained or can
be created so as to functionally and visually separate the two sites
or where compatible conventionally built homes will be located in
the mobile home development adjacent to the existing residences.
[Amended 10-9-1990 by Ord. No. 175]
H.
Any site proposed for a mobile home development shall,
in the opinion of the Board of Supervisors, be easily accessible to
essential community facilities and services, such as employment centers,
shopping centers, schools and police and fire protection and shall
be within one mile by road or pedestrian walkway to existing or planned
convenience commercial facilities. The site should also preferably
be within that same one-mile distance of existing or planned public
transit routes (if available).
I.
Every area to be used as a mobile home development
must be served exclusively by the municipal sanitary waste disposal
system and a centralized water supply system, if those facilities
are available, and if each system is found to contain the available
capacity to serve the proposed development; or, alternately, the area
to be used as a mobile home development must, if it cannot connect
to either or both the centralized water supply and municipal sanitary
sewer systems, be served by a common single water supply system serving
all dwelling units and other structures in the development and/or
a common single sanitary sewer system doing likewise, either or both
of which, as applicable, must have the approval of the Pennsylvania
Department of Conservation and Natural Resources. Furthermore, those
on-site facilities must, when constructed, meet the following criteria:
(1)
The satellite system shall be designed and constructed
in a manner that will permit adequate connection to the centralized
or public system in the future.
(2)
The administrative structure for the satellite system
shall be organized in a manner that will facilitate easy interconnection
of the two systems.
(3)
The developer shall be required to show proof that
the satellite system extended to serve the proposed development will
not interfere with any existing sewage disposal system or any existing
water supplies, be they wells for nearby properties or sources of
water for other community systems.
(4)
When the centralized or public system reaches the
development site, connection to it shall be mandatory, and the cost
of the eventual interconnection shall be borne by the developer, or
the organization that is set up to own and operate the satellite system.
(5)
If, after development occurs, the satellite water
system is deemed to be the cause of interference with existing water
supplies or the satellite sewer system is deemed to be the cause of
any pollution, extension of the centralized or public systems may
be required at that time. The cost of the extension and hookup shall
be borne by the developer or organization owning and operating the
satellite system.
J.
Access to public thoroughfares.
(1)
Any tract intended for a mobile home development must
have direct access to a feeder-type road (or a road of a higher classification),
as defined by the Township Official Map Summary, which the Township
Board of Supervisors deems capable of accommodating the transport
of mobile home units, upon recommendation of the Township Engineer.
(2)
Plans evidencing provision for safe and efficient
ingress and egress to and from the public streets and highways servicing
mobile home developments without causing undue confusion or interference
with the normal traffic flow shall be submitted to the Township Board
of Supervisors and must be approved by the Township Engineer, who
shall make the determination based on the adequacy of the thoroughfare
to carry the additional traffic generated by the mobile home development.
K.
The applicant shall demonstrate, to the satisfaction of the Board of Supervisors, that he has complied with or will comply with all requirements of Chapter 179 of Title 25, Part 1, Subpart D, Article II, of the Rules and Regulations of the Pennsylvania Department of Conservation and Natural Resources and with all other pertinent regulations of the Commonwealth of Pennsylvania which are applicable to mobile home parks.
The total number of lots in a mobile home development
shall not exceed a maximum density of four per developable acre. All
area not contained in developable acreage as defined in this chapter
shall be excluded from density calculations.
[Amended 10-9-1990 by Ord. No. 175]
A.
The lot size requirements under the R-50 Residential
District may be reduced a maximum of 50%, and the lot width and yard
setbacks may be reduced a maximum of 25%, for lots which will be used
for conventionally built single-family detached homes located within
the mobile home development. The following standards shall apply to
zero-lot-line homes within the mobile home development:
A.
Setback from tract boundary. No mobile home or other
primary building may be located closer than 40 feet to any boundary
of a mobile home development, regardless of whether that boundary
abuts a lot, water body, road or other right-of-way. In the event
that a mobile home development abuts another such development or R-50
Residential District, this provision shall not apply; however, all
other applicable setbacks prescribed herein shall apply.
[Amended 10-9-1990 by Ord. No. 175]
B.
Setback from streets. In no case shall the long side
of a mobile home or any side of another primary building or accessory
use be located closer than 25 feet to the ultimate right-of-way line
of any public street or to the edge of the cartway, or the equivalent
right-of-way line, if applicable, of private interior roadways or
to the edge of any common pedestrian walkway, within a mobile home
development; provided, however, that the short side of a mobile home
may be located no closer to these facilities than 15 feet. No more
than six homes in a row shall have the same setback; where varied
setbacks are utilized, the difference shall be at least four feet.
C.
Setback from common parking facilities. No mobile
home or accessory use shall be located within 25 feet of any common
parking area.
D.
Lot size. All mobile home lots in a mobile home development,
regardless of tenure, shall have a minimum lot size of 5,000 square
feet when on-lot parking is provided, excluding the area of any access
leg to a rear lot, except that this may be reduced to no less than
4,500 square feet when common parking is provided.
E.
Lot width. No individual mobile home lot shall be less than 55 feet in width at the building setback line, although this may be reduced to 45 feet where roofed additions are prohibited or where the applicant can demonstrate that roofed additions can be added without violating the provisions Subsections F and H herein. No individual mobile home lot shall be less than 25 feet in width at the right-of-way line of a public street or the equivalent right-of-way line or the edge of the pavement of a private street, as applicable.
F.
Side and rear setbacks. No mobile home or accessory building may be located closer than four feet to any side or rear lot line of an individual mobile home lot; provided, however, that all minimum requirements of Subsection H must be met, and provided further that accessory buildings may be located on the lot line if physically joined to each other with a common wall located on the property line.
G.
Unit location on individual lots. Mobile homes placed on individual lots are encouraged to utilize the minimal setbacks specified in Subsection F and to be placed off-center on the lots so as to provide a large usable open yard space and outdoor living area in one section of the lot.
H.
Distance between structures. Mobile homes and roofed
structures or areas attached thereto shall be separated from each
other and from other buildings and structures, other than accessory
structures, at their closest points by a minimum of 20 feet; provided,
however, that whenever two mobile homes have their longer sides parallel
or essentially parallel to each other for more than 25% of the length
of either, the minimum distance between the two mobile homes shall
be 30 feet. The sides shall be considered essentially parallel if
they form an angle of less than 45º when extended to intersect.
I.
Lot coverage. The maximum coverage of any individual
mobile home lot shall be no greater than 35%.
[Amended 10-9-1990 by Ord. No. 175; 1-20-2020 by Ord. No. 409]
J.
Height. No structure built in a mobile home development
shall exceed a height of three stories or a maximum of 35 feet.
K.
Design alternative. In order to allow clustering of lots designed to encourage flexibility in site design and preservation of natural features and to maximize creation of accessibility of recreation areas, the distance between structures, minimum lot width and minimum lot size may be reduced up to a maximum of 10% upon approval of the governing body, provided that at least 50% of all lots so reduced shall directly abut a part of the common open space for a distance of at least 20 feet. An area equal to that by which each lot is reduced shall be added to the minimum common open space specified in § 145-52.
At least 20% of the site area of the mobile
home development must be in common open space as defined herein, no
more than 1/3 of which may be required buffer area.
