All manufactured and mobile home communities and modifications
of or additions or extensions to existing communities shall comply
with the following:
A. Chapter SPS 326, Wis. Adm. Code, as now existing or hereafter amended,
is hereby made a part of this chapter and incorporated herein by reference
as if fully set forth, except that such regulations shall not be deemed
to modify any requirement of this chapter or any other applicable
law or ordinance of the state or City.
B. Manufactured and mobile home spaces shall be a minimum of 50 feet
wide and 100 feet in depth, have a setback of 20 feet from all street
rights-of-way, and have a side yard setback of 10 feet, except that
driveways may extend to within four feet of a property line. Accessory
structures, such as awnings, cabanas, storage cabinets, carports,
windbreaks or attached porches, shall be considered part of the unit
for purposes of determining compliance with this provision. No manufactured
and mobile home site shall be rented for a period of less than 30
days. There shall be two surfaced automobile parking spaces for each
manufactured and mobile home. Unless adequately screened by existing
vegetative cover, a manufactured and mobile home community shall be
screened around its outer perimeter by a planting of hedges or trees
capable of reaching a height of 15 feet or more, the individual trees
to be such a number and so arranged that within 10 years they will
have formed a screen equivalent in opacity to a solid fence or wall.
Such permanent planting shall be grown or maintained to a height of
not less than 15 feet when mature.
C. No manufactured and mobile home community shall be laid out, constructed
or operated without City sanitary sewer service.
D. All liquid wastes originating at units, service or other buildings
shall be discharged into a sewerage system extended from and connected
with the public sewerage system. Such systems shall comply with all
provisions of the state code and City ordinances relating to plumbing
and sanitation. Each individual space shall be provided with a three-inch
watertight sewer connection protected from damage by heaving and thawing
or parking of the unit and located within the rear 1/3 of the stand,
with a continuous grade which is not subject to surface drainage,
so constructed that it can be closed when not in use and trapped in
such a manner that it can be kept odor-free.
E. Adequate provision shall be made for the disposal of solid and liquid
wastes in a manner approved by the Common Council. Open burning of
waste or refuse is prohibited.
F. All television cable systems, electrical and telephone distribution
lines and oil or gas piping serving the community or spaces therein
shall be installed underground. Distribution systems shall be new
and all parts and installations shall comply with all applicable federal,
state and local codes.
G. Each space shall be provided with direct electrical service of not
less than 100 amperes for 220 volt service.
H. A minimum of two off-street parking spaces surfaced with bituminous
concrete or similar material capable of carrying a wheel load of 4,000
pounds shall be provided for each manufactured and mobile home space.
I. Condition of soil, groundwater level, drainage and topography shall
not create hazards to the property, health or safety of occupants
of manufactured and mobile home spaces or living units. The site shall
not be exposed to objectionable smoke, noise, odors or other adverse
influences, and no portion subject to unpredictable and sudden flooding,
subsidence or erosion shall be used for any purpose which would expose
persons or property within or without the community to hazards.
J. Exposed ground surfaces in all parts of every manufactured and mobile
home community shall be paved or covered with stone screenings or
other solid material or protected with a vegetative growth that is
capable of preventing soil erosion and eliminating objectionable dust.
K. The ground surface in all parts of every manufactured and mobile
home community shall be graded and equipped to drain all surface water
in a safe, sanitary and efficient manner.
L. All communities shall be furnished with individual outdoor lot lighting
of 25 to 60 watts so spaced and equipped with luminaires placed for
the safe movement of pedestrians and vehicles at night.
M. All manufactured and mobile home spaces shall abut upon a street.
All streets shall be provided with a smooth, hard and dense surface
which shall be well drained under normal use and weather conditions
for the area. Pavement edges shall be curbed and protected to prevent
raveling of the wearing surface and shifting of the pavement base.
Grades of streets shall be sufficient to ensure adequate surface drainage
but not more than 8%, provided that a maximum grade of 12% may be
used if approved by the Director of Public Works as safe and designed
to avoid traffic hazards. Streets shall be at approximately right
angles within 100 feet of an intersection. Intersections of more than
two streets at one point shall not be allowed. A distance of at least
150 feet shall be maintained between center lines of offset intersecting
streets.
N. All communities shall be provided with pedestrian walks between individual
manufactured and mobile homes, community streets and community facilities
of not less than three feet in width. Grade and surfacing of walks
shall be approved by the City Engineer as safe and comparable to sidewalks
in other areas of the municipality subject to similar usage, except
that, as an alternative, inverted curbing may be used which provides
approximately three feet of concrete walking area adjacent to the
curbline.
O. All manufactured and mobile home communities shall have a greenbelt
or buffer strip not less than 10 feet wide along all boundaries. Unless
adequately screened by existing vegetative cover, all manufactured
and mobile home communities shall be provided within such greenbelt
or buffer strip with screening of natural growth or screen fence,
except where the adjoining property is also a manufactured and mobile
home community. Compliance with this requirement shall be made within
five years from the granting of the manufactured and mobile home community
developer's permit. Screening or planting requirements may be waived
or modified by the governing body if it finds that the exterior architectural
appeal and functional plan of the community, when completed, will
be materially enhanced by modification or elimination of such screen
planting requirements.
P. Manufactured and mobile home community operators shall, at the time of approval, pay the park development fees required for conventional subdivisions in §
510-47.
Q. Single-family nondependent manufactured and mobile homes and approved
accessory structures included in the original plans and specifications
or revisions thereof, parks, playgrounds, open space, off-street parking
lots, one community office and service buildings for exclusive use
of community residents shall be the only permitted uses in manufactured
and mobile home communities, provided that the Common Council may
approve the following uses when designed and limited to exclusive
use of community residents:
(2) Clubhouses and facilities for private, social or recreation clubs.
R. No signs shall be erected in manufactured and mobile home communities.
S. All manufactured and mobile home communities shall be provided with
safe and convenient vehicular access from abutting public streets
or roads to each manufactured and mobile home space. Entrances to
communities shall be designed to minimize congestion and traffic hazards
and allow free movement of traffic on adjacent streets.
All plumbing, electric, electrical, building and other work
on or at any manufactured and mobile home community under this chapter
shall be in accordance with the ordinances of the City and the requirements
of the State Plumbing, Electrical and Building Codes and the regulations
of the State Department of Safety and Professional Services. Licenses
and permits granted under this chapter grant no right to erect or
repair any structure, to do any plumbing work or to do any electric
work.
The following guides, standards and requirements shall apply
in site planning for manufactured and mobile home communities:
A. Principal vehicular access points. Principal vehicular access points
shall be designed to encourage smooth traffic flow with controlled
turning movements and minimum hazards to vehicular or pedestrian traffic.
Merging and turnout lanes and/or traffic dividers shall be required
where existing or anticipated heavy flows indicate need. In general,
minor streets shall not be connected with streets outside the district
in such a way as to encourage the use of such minor streets by substantial
amounts of through traffic. No lot within the community shall have
direct vehicular access to a street bordering the development.
B. Access for pedestrians and cyclists. Access for pedestrians and cyclists
entering or leaving the community shall be by safe and convenient
routes. Such ways need not be adjacent to or limited to the vicinity
of vehicular access points. Where there are crossings of such ways
and vehicular routes at edges of planned developments, such crossings
shall be safety located, marked and controlled and where such ways
are exposed to substantial vehicular traffic at edges of communities,
safeguards may be required to prevent crossings except at designated
points. Bicycle paths, if provided, shall be so related to the pedestrian
way system that street crossings are combined.
C. Protection of visibility for automotive traffic, cyclists and pedestrians. At intersections of any streets, public or private, the provisions of §
635-53 shall apply and are hereby adopted by reference.
D. Ways for pedestrians and/or cyclists in exterior yards. In any exterior
yard, required or other, ways for pedestrian and/or cyclists may be
permitted, if appropriately located, fenced or landscaped to prevent
potential hazards arising from vehicular traffic on adjacent streets
or other hazards and annoyances to users or to occupants of adjoining
property. When otherwise in accord with the requirements concerning
such ways set forth above, approved ways in such locations shall be
counted as common recreation facilities and may also be used for utility
easements.
E. Internal relationships. The site plan shall provide for safe, efficient,
convenient and harmonious groupings of structures, uses and facilities
and for appropriate relation of space inside and outside buildings
to intended uses and structural features. In particular:
(1)
Streets, drives and parking and service areas. Streets, drives
and parking and service areas shall provide safe and convenient access
to dwellings and community facilities and for service and emergency
vehicles, but streets shall not be so laid out as to encourage outside
traffic to traverse the community, nor occupy more land than is required
to provide access as indicated, nor create unnecessary fragmentation
of the community into small blocks. In general, block size shall be
the maximum consistent with use, the shape of the site and the convenience
and safety of the occupants.
(2)
Vehicular access to streets. Vehicular access to streets from
off-street parking areas may be direct from dwellings if the street
or portion of the street serves 50 units or fewer. Determination of
units served shall be based on normal routes anticipated for traffic.
Along streets or portions of streets serving more than 50 dwelling
units, or constituting major routes to or around central facilities,
access from parking and service areas shall be so combined, limited,
located, designed and controlled as to channel traffic conveniently,
safely and in a manner that minimizes marginal traffic friction, and
direct vehicular access from individual dwellings shall generally
be prohibited.
(3)
Ways for pedestrians and cyclists; use by emergency, maintenance
or service vehicles.
(a)
Walkways shall form a logical, safe and convenient system for
pedestrian access to all dwellings, project facilities and principal
off-street pedestrian destinations. Maximum walking distance in the
open between dwelling units and related parking spaces, delivery areas
and trash and garbage storage areas intended for use of occupants
shall not exceed 100 feet.
(b)
Walkways to be used by substantial numbers of children as play
areas or routes to school, bus stops or other destinations shall be
so located and safeguarded as to minimize contracts with normal automotive
traffic. If an internal walkway system is provided, away from streets,
bicycle paths shall be incorporated in the walkway system. Street
crossings shall be held to a minimum on such walkways and shall be
located and designated to provide safety and shall be appropriately
marked and otherwise safeguarded. Ways for pedestrians and cyclists,
appropriately located, designed and constructed may be combined with
other easements and used by emergency, maintenance or service vehicle
but shall not be used by other automotive traffic.
