The R-1 through R-3 Single-Family Residential Districts are
intended to provide sites for single-family detached dwellings and
residentially related uses that serve the residents in the district.
These districts provide a range of housing opportunities from larger
suburban lots to more compact urban neighborhoods. These districts
are intended to create walkable neighborhoods that are integrated
into the character of the City. It is also the intent of these districts
to protect natural areas and include recreational open space within
neighborhoods and throughout the City. Further, it is the intent of
the Single-Family Residential Districts to eliminate multiple-family
residential uses in these districts.
Buildings or land shall be not used and buildings shall not
be erected except for one or more of the following specified uses,
unless otherwise provided for in this chapter. Land and/or buildings
in the districts indicated at the top of Table 7.03.1 may be used
for the purposes denoted by the following abbreviations:

|
Recreational area. All residential developments containing more
than six dwelling units shall provide a recreational area of at least
1,500 square feet for each residential unit. The location of the area
shall be approved by the City Commission, based upon a recommendation
by the Planning Commission.
| |
|
2
|
Depth-to-width ratio. All lots created after the adoption date
of this chapter shall have a lot depth not more than four times its
width, as measured at the front lot line.
| |
|
3
|
Building height. Exceptions to building height shall be as provided for in § 7-14.03A, Height limit.
| |
|
4
|
Averaged lot size. The intent of this section is to permit the
subdivider or developer to vary lot sizes and lot widths so as to
average the minimum size of lot per unit as required in Table 7.03.2
for each Single-Family Residential District. If this option is selected,
the following conditions shall be met:
| |
|
a.
|
In meeting the average minimum lot size, the subdivision shall
be so designed that lot areas and widths shall not be reduced by more
than 10% below that area or width required and shall not create an
attendant increase in the number of lots.
| |
|
b.
|
Each final plat submitted as part of a preliminary plat shall
average the minimum required for the district in which it is located.
| |
|
c.
|
All computations showing lot area and the average resulting
through this technique shall be indicated on the print of the preliminary
plat.
| |
|

| ||
|
6
|
Nonresidential setbacks. For all uses permitted other than single-family residential, the setback shall equal the height of the main building, unless otherwise specified in Article XIII, Use Requirements. A setback and screening buffer as listed in Table 7.15.1 is required when a rear or side lot line is adjacent to different zoning district or use.
| |
|
7
|
Natural features setback. All structures shall be set back at
least 25 feet from all natural features such as drains, regulated
wetlands, natural ponds, lakes and streams.
| |
|
8
|
Front yard reduction. The required front yard setback may be
reduced to an average of the existing front yard setbacks of residences
immediately adjacent on the same street. If no adjacent residences
exist, then the front yard setback may be reduced to an average of
the nearest two residences on the same street.
| |
|
9
|
Rear yards abutting a side yard. In the case of a rear yard
abutting a side yard, the side yard setback abutting a street shall
not be less than the minimum front yard setback of the district in
which located and all regulations applicable to a front yard shall
apply. On corner lots where a lot width of 60 feet or less exists,
the side yard may be reduced to the front setback of the home to the
rear of such corner lot.

A.
The intent of the Subdivision Open Space Plan is to promote the following
objectives:
(1)
Provide a more desirable living environment by preserving the natural
character of open fields, stands of trees, brooks, hills and similar
natural assets.
(2)
Encourage developers to use a more creative approach in the development
of residential areas.
(3)
Encourage a more efficient, aesthetic and desirable use of open area
while recognizing a reduction in development costs and allowing the
developer to bypass natural obstacles on the site.
(4)
Encourage the provision of open space within reasonable distance
to all lot development of the subdivision and to further encourage
the development of recreational facilities.
B.
Modification to the standards outlined in Table 7.03.2 may be made
in the R-2 and R-3 Single-Family Residential Districts when the following
conditions are met:
(1)
The lot area in R-2 Single-Family Residential Districts, which are
served by a public sanitary sewer system, may be reduced up to 20%.
In the R-2 District, this reduction may be accomplished in part by
reducing lot widths up to five feet. In the R-3 Districts, this reduction
may be accomplished in part by reducing lot widths up to 10 feet.
These lot area reductions shall be permitted, provided that the dwelling
unit gross density shall be no greater than if the land area to be
subdivided were developed in the minimum square foot lot areas as
required for each Single-Family District under Table 7.03.2. All calculations
shall be predicated upon the Single-Family Districts having the following
gross densities (including roads):
(2)
Rear yards may be reduced to 30 feet when such lots border on land
dedicated for park, recreation and/or open space purposes, provided
that the width of said dedicated land shall not be less than 100 feet
measured at the point at which it abuts the rear yard of the adjacent
lot.
(3)
Under the provisions of Subsection B(1) above of this section, for each square foot of land gained within a residential subdivision through the reduction of lot size below the minimum requirements as outlined in Table 7.03.2, at least equal amounts of land shall be dedicated to the common use of the lot owners of the subdivision in a manner approved by the municipality.
(4)
The area to be dedicated for subdivision open space purposes shall
in no instance be less than three acres and shall be in a location
and shape approved by the Planning Commission.
(5)
The land area necessary to meet the minimum requirements of this
section shall not include bodies of water, swamps or land with excessive
grades making it unsuitable for recreation. All land dedicated shall
be so graded and developed as to have natural drainage. The entire
area may, however, be located in a floodplain.
(6)
This plan, for reduced lot sizes, shall be permitted only if it is
mutually agreeable to the legislative body and the subdivider or developer.
(7)
This plan for reduced lot sizes shall be started within 12 months
after having received approval of the final plat and must be completed
in a reasonable time. Failure to start within this period shall void
all previous approval.
(8)
Under this subdivision open space approach, the proprietor shall
dedicate sufficient park area for the common use of the lot owners
so that each final plat is within maximum density requirements; provided,
however, that any entire park within a single block shall be dedicated
as a whole.
C.
The application for approval of Subdivision Open Space Plan shall contain the following in addition to the information required by Chapter 6, Land Division:
(1)
A complete description of the land proposed to be dedicated to the
City or to the common use of lot owners (herein called "open land"),
including the following, at a minimum:
(2)
The proposed plan of development of the open land shall be contained
in the application and shall include the following, at a minimum:
(a)
The proposed manner in which the title to land and facilities
is to be held by the owners of land in the subdivision.
(b)
The proposed manner of collection of maintenance costs, financing
costs or assessments so that nonpayment will constitute a lien on
the property, thus avoiding municipal responsibility in the future.
(c)
The proposed manner of regulating the use of the common facilities
and areas so as to eliminate possible nuisances to the property owners
and cause for enforcement by the City.
(d)
The proposed method of notifying the City when any change is
contemplated in plans that would affect the original specifications
approved by the City.
(e)
The proposed method of setting up assessments to cover contingencies,
insurance against casualty and liability and payment of taxes relating
to these properties.
(f)
The proposed use of open land and the proposed improvements
which are to be constructed by the proprietor.
(3)
The application shall contain a statement of the benefits to be realized
by the residents of the proposed subdivision and the City by approval
of the proposed Subdivision Open Space Plan with particular reference
to the objectives stated in this chapter.
D.
Subdivision Open Space Plans shall follow the review and approval procedures for subdivisions, including all public hearing requirements, as set forth in Chapter 6, Land Division.
(1)
If the Planning Commission is satisfied that the proposed Subdivision Open Space Plan is in compliance with this chapter and should be approved, it shall recommend such approval to the City Commission with the conditions upon which such approval should be based. Thereafter, the City Commission shall take action upon such application in accordance with the procedures for subdivisions set forth in Chapter 6, Land Division.
(2)
If the Planning Commission is not satisfied that the proposed Subdivision
Open Space Plan is in compliance with this chapter or finds that the
approval of said Subdivision Open Space Plan will be detrimental to
existing development in the general area and should not be approved,
it shall communicate such disapproval to the City Commission with
the reasons therefor. The proprietor shall be entitled to a hearing
upon said proposal before the City Commission upon written request
filed with the Clerk.
(3)
If the City Commission gives approval to the proposed Subdivision
Open Space Plan, it shall instruct its attorney to prepare a contract
setting forth the conditions on which such approval is based, which
contract, after approval by the City Commission, shall be entered
into between the City and the proprietor prior to the approval of
a preliminary plat.
A.
Intent.
(1)
The intent of this section is to permit the development of single-family
residential patterns which, through design innovation, will provide
for an alternative means for development of single-family areas. To
accomplish this, modifications to the single-family residential standards,
as outlined in Table 7.03.2, shall be permitted in the R-2 and R-3
Districts.
(2)
In R-2 and R-3 Single-Family Residential Districts, the requirements
of Table 7.03.2 may be waived and the attaching of single-family dwelling
units may be permitted, subject to the standards of this section.
B.
Conditions for qualification.
(1)
The Planning Commission may approve of the clustering or attaching
of dwelling units on parcels of land under single ownership and control
which, in the opinion of the Planning Commission, have characteristics
which would make sound physical development under the normal subdivision
approach impractical because of parcel size, shape or dimension or
because the site is located in a transitional use area or the site
has natural characteristics which are worth preserving or which make
platting difficult. In approving an area for cluster development,
the Planning Commission shall find at least one of the following conditions
to exist:
(a)
The parcel to be developed has frontage on a major or secondary
thoroughfare and is generally parallel to said thoroughfare and is
of shallow depth as measured from the thoroughfare.
(b)
The parcel has frontage on a major or secondary thoroughfare
and is of a narrow width, as measured along the thoroughfare, which
makes platting difficult.
(c)
The parcel is shaped in such a way that the angles formed by
its boundaries make a subdivision difficult to achieve and the parcel
has frontage on a major or secondary thoroughfare.
(d)
A substantial portion of the parcel's perimeter is bordered
by a major thoroughfare which would result in a substantial proportion
of the lots of the development abutting the major thoroughfare.
(e)
A substantial portion of the parcel's perimeter is bordered
by land that is located in other than an R Single-Family Residential
District or is developed for a use other than single-family detached
homes.
(f)
The parcel contains a floodplain or poor soil conditions which
result in a substantial portion of the total area of the parcel being
unbuildable.
(g)
The parcel contains natural land forms which are so arranged
that the change of elevation within the site includes slopes in excess
of 10% between these elevations. These elevation changes and slopes
shall appear as the typical feature of the site rather than the exceptional
or infrequent features of the site. The topography is such that achieving
road grades of less than that permitted by the City could be impossible
unless the site were mass graded. The providing of single-family clusters
will, in the opinion of the Planning Commission, allow a greater preservation
of the natural setting.
(h)
The parcel contains natural assets which would be preserved
through the use of cluster development. Such assets may include natural
stands of large trees, land which serves as a natural habitat for
wildlife, unusual topographic features or other natural assets which
should be preserved.
(2)
In order to qualify a parcel for development under Subsection B(1)(f), (g) or (h) above, the Planning Commission shall determine that the parcel has these characteristics and the request shall be supported by written and/or graphic documentation, prepared by a landscape architect, engineer, professional community planner, registered architect or environmental design professional. Such documentation shall include the following as appropriate: soil test borings, floodplain map, topographic map of maximum two-foot contour interval, inventory of natural assets.
(3)
This option shall not apply to those parcels of land which have been
split for the specific purpose of coming within the requirements of
this cluster option section.
C.
Permitted densities. In a cluster development, the gross densities
permitted may be increased to the following maximums (including streets):
(3)
Water areas within the parcel may be included in the computation
of density, provided that land adjacent to the water is substantially
developed as open space.
(4)
In those instances where a parcel qualifies under both Subsection C(1) and (2) above, the densities permitted under Subsection C(1) may be permitted by the Planning Commission, provided that the Commission finds that such density is reasonable in that it does not preclude the application of Subsection D(5) and does not result in the destruction or total removal of such natural assets as enumerated under Subsection B(1)(f), (g) or (h) above.
D.
Development standards and requirements. In areas meeting the criteria of Subsection B(1) above, the minimum yard setbacks, heights and minimum lot sizes per unit as required by Table 7.03.2, may be waived and the attaching of dwelling units may be accomplished, subject to the following:
(1)
The attaching of single-family dwelling units, one to another, may
be permitted when said homes are attached by means of one of the following:
(a)
Through a common party wall which does not have over 50% of
its area in common with an abutting dwelling wall.
(b)
By means of an architectural wall detail which does not form
interior room space.
(c)
Through a common party wall in only the garage portion of adjacent
structures.
(d)
No other common party wall relationship is permitted and the
number of units attached in this manner shall not exceed four.
(2)
Yard requirements shall be provided as follows:
(a)
Spacing between groups of attached dwelling units or between
groups of four unattached units shall be equal to at least 20 feet
in an R-3 District, and 15 feet in an R-2 District, measured between
the nearest points of adjacent buildings.
(b)
Building setbacks from local streets shall be determined after
consideration of potential vehicular traffic volume, site design and
pedestrian safety. It is intended that setbacks for each dwelling
shall be such that one car length space will be available between
the garage or required off-street parking spaces and the street pavement.
In determining the setbacks from local streets, the Planning Commission
may use the following guidelines:
[1]
Garages or required off-street parking spaces shall not be located
less than 20 feet from the right-of-way of a public street unless
such street (or portion thereof) is serving as access to not more
than 16 residential units.
[2]
Where streets are private or the Planning Commission does not
require the twenty-foot setback from a public right-of-way, garages
or required off-street parking spaces shall not be located less than
20 feet from the pavement edge of the street or the shoulder of a
street.
(c)
That side of a cluster adjacent to an arterial or collector street shall not be nearer to said street than 25 feet, except that in those areas where topography meets the topographic conditions set forth in § 7-3.05B(1)(g) above on lands immediately adjacent to said streets having slopes in excess of 10%, the front yard may be reduced by five feet, but in no instance shall a structure be closer to the road right-of-way line than 1/2 the front yard setback for the district in which it is located.
(d)
Any side of a cluster adjacent to a private road shall not be
nearer to said road than 10 feet.
(3)
In computing the height of any individual dwelling unit in a cluster
on a slope in excess of 10% and when the unit is constructed on posts,
the first 10 feet of height in the posts shall not be computed. Application
of the definition of "building height" shall apply over and above
the 10 feet of post height.
(4)
The area in open space (including subdivision recreation areas and
water) accomplished through the use of one-family cluster shall represent
at least 20% of the horizontal development area of a one-family cluster
development.
(5)
In order to provide an orderly transition of density, where the parcel
proposed for use as a cluster development abuts a one-family residential
district, the Planning Commission shall determine that the abutting
one-family district is effectively buffered by means of one of the
following within the cluster development:
(a)
Single-family lots subject to the standards of Table 7.03.2.
(b)
Detached buildings with setbacks as required by Table 7.03.2
for the applicable residential district.
(c)
Open or recreation space.
(d)
Changes in topography which provide an effective buffer.
(e)
A major or secondary thoroughfare.
E.
Procedures.
(1)
In making application for approval under this section, the applicant
shall file a sworn statement that the parcel has not been split for
the purpose of coming within the requirements of this option, and
shall further file a sworn statement indicating the date of acquisition
of the parcel by the present owner.
(2)
Qualification for cluster development.
(a)
Application to the Planning Commission for qualification of a parcel for cluster development shall include documentation substantiating one or more of the characteristics outlined in Subsection B, Conditions for qualification.
(b)
The Planning Commission shall make a preliminary determination as to whether or not a parcel qualifies for the cluster option under one of the provisions of Subsection B(1) above, based upon the documentation submitted.
(c)
Preliminary determination by the Planning Commission that a
parcel qualifies for cluster development does not assure approval
of the site plan and, therefore, does not approve the cluster option.
It does, however, give an initial indication as to whether or not
a petitioner should proceed to prepare a site plan.
(3)
Site plan and cluster approval.
(a)
The Planning Commission shall hold a public hearing on the site
plan after an initial review of a preliminary plan which shall not
require a public hearing.
(b)
In submitting a proposed layout under this section, the sponsor
of the development shall include, along with the site plan, typical
building elevations and floor plans, topography drawn at two-foot
contour intervals, all computations relative to acreage and density,
a preliminary grading plan, and any other details which will assist
in reviewing the proposed plan.
(c)
For those parcels which qualified under the provisions of Subsection B(1)(f), (g) or (h), one copy of the site plan superimposed on a recent aerial photograph of at least one-inch-equals-200-feet scale, shall be submitted for review to show the relationship of the site plan to existing natural features and to adjacent developments.
(d)
Site plans submitted under this option shall be accompanied by information as required in § 7-3.04C Subdivision Open Space Plan, provided, however, that:
(e)
The Planning Commission shall give notice of the public hearing in accordance with § 7-21.07, Public hearings.
(f)
If the Planning Commission is satisfied that the proposal meets
the letter and spirit of the Zoning Ordinance and should be approved,
it shall give tentative approval with the conditions upon which such
approval should be based. If the Planning Commission is not satisfied
that the proposal meets the letter and spirit of the Zoning Ordinance,
or finds that approval of the proposal would be detrimental to existing
development in the general area and should not be approved, it shall
record the reasons therefor in the minutes of the Planning Commission
meeting. Notice of approval or disapproval of the proposal, together
with copies of all layouts and other relevant information, shall be
forwarded to the City Clerk. If the proposal has been approved by
the Planning Commission, the Clerk shall place the matter upon the
agenda of the City Commission. If disapproved, the applicant shall
be entitled to a hearing before the City Commission, if he requests
one in writing within 30 days after action by the Planning Commission.
(g)
The City Commission shall conduct a public hearing on the proposed open space plan and site plan for the cluster option and shall give notice in accordance with § 7-21.07, Public hearings. If the City Commission approves the plans, it shall instruct the City Attorney to prepare a contract, setting forth the conditions upon which such approval is based, which contract, after approval by the City Commission, shall be entered into between the City and the applicant prior to the issuance of a building permit for any construction in accordance with site plans.
(h)
As a condition for the approval of the site plan and open space
plan by the City Commission, the applicant shall deposit a cash or
irrevocable letter of credit in the amount of the estimated cost of
the proposed improvements to the open land guaranteeing the completion
of such improvement within a time to be set by the City Commission.
Actual development of the open space shall be carried out concurrently
with the construction of dwelling units.
