Overview
At the February 13th and February 27th Planning Commission meetings, the
Commission and staff discussed concerns that have been raised by the City
Council, the Planning Commission and staff. The Commission then gave staff
direction regarding amendments to the cluster ordinance to address the
issues raised.
Cluster Developments in the A1 District
The Commission had a lengthy discussion of the use of cluster developments
in the A1 district. We discussed whether the density bonus is too high and
whether limiting the use of the ordinance to within a certain distance of the
existing developed areas would control cluster developments. The
Commission felt that neither of these options would effectively reduce the use
of cluster developments in the outer reaches of the City. Furthermore, the
Commission did not feel use of cluster developments in the northern portion
of the A1 district was a major problem.

Quality of Open Space
As a method to preserve higher quality open space, the Commission
suggested that at least 35% of the open space be "buildable area". Buildable
area is defined as gross land area less the land that includes floodways,
hydric and restrictive soils, lands with slopes greater than 33%, wetlands,
and areas that can not accommodate septic systems. The ordinance should
also be amended to give the City the option of requiring that shoreland and
areas along streams be included as preserved open space.
The Commission also thought that the 5% density bonus for additional 10%
open space, above the required 50%, should only given if the additional 10%
is buildable.
The Commission felt that the maximum lot size allowed should be 2~A acres
and that if the maximum lots size is % acre there should be a 5% density
bonus.
Architectural Theme
The Commission felt a written narrative describing the architectural theme
of a project should be provided at the same time that the preliminary plat is
submitted. The 5% bonus should also be further broken down. Landscape
theme, lighting theme and a common open space/central gathering place
would make up 2.5% of the density bonus and additional architectural
elements would make up 2.5% of the density bonus.
Front Yard Setback
The current minimum front yard setback of 30 feet is too restrictive and does
not allow developers to create more pedestrian friendly, walkable
neighborhoods. By reducing the minimum front yard setback to 20 feet, a
developer would have more flexibility in design and additional trees could be
preserved. The Commission wanted the garages to have a less dominant
presence in the streetscape and recommend that garages be setback back
further than the house. A 30 foot minimum setback for garages was
recommended.
Density Bonus Calculations
It is currently not clear how the 5% density bonus should be calculated,
whether it is based on zoning district density or the open space density. The
intention was that it should be based on the zoning district density, and the
following formula should be included to make it clear:

Page 3
Rla district - eligible land 24 ac.
Density bonus: (24/2.5) x .05 - .48
In this example each 5% density bonus would be worth .48 lots
A1 district - eligible land 42 ac.
Density bonus: (42/10) x .05 -- .21
In this example each 5% density bonus would be worth .21 lots
Park Dedication Requirements
The Commission also reviewed the park dedication requirements. Under the
current ordinance the park dedication fee is based on the number of lots
allowed per based density, not on the total number of lots platted.
For instance, with Ridges of Rice Lake, the park dedication fee would be
based on the base density allowed under the A1 zoning district (273 ac./10 -
27.3 or 27 lots). The alternative would be based on the total number of lots
platted, which in this case is 70.
The Commission recommended that park dedication requirements be based
on the total number of lots platted.
Recommendation
The Planning Commission and staff recommend that the City council approve
attached ordinance amendment approving the following amendments to the
cluster ordinance:
1. 35% of the preserved open space be buildable area.
2. The City have the option of requiring that shoreline and areas along
streams be included as preserved open space.
3. The additional 10% open space, above the required 50%, provided to
receive the 5% density bonus be buildable area.
4. The maximum lot size allowed shall be 2 ½ acres.
5. If the maximum lot size in a project is ½ acre or less, the developer will
receive a 5% density bonus.
6. Landscape theme, lighting theme and a common open space/central
gathering place would make up 2.5% of the 5% density bonus for
architectural theme and the architectural theme of the houses would
make up other 2.5% of the density bonus.
7. A written narrative describing the architectural theme of a project be
provided with the submittal of the preliminary plat.
8. The minimum front yard setback for house shall be 20 feet and the
minimum front yard setback for garages shall be 30 feet.

be designed to achieve one or more of the following
objectives:
a. Oriented around a central focal point such
as:
i) A central green or square
ii) A physical amenity such as a meadow,
stand of trees, a stream or water body, or
some other natural feature.
iii) A street with a boulevard planted with
shade trees and a central parkway or median
at least 25 feet wide.
b. Located to preserve woodlands, farmland or
other natural features or character including
places of historic, archeological or cultural
value and their environs.
c. Located such that at least 50% of the lots
within a neighborhood abut open space on at least
one side. A local street may separate lots from
open space.
d. Views shall be preserved on and off-site to
the maximum possible.
e. Locate neighborhood recreation open spaces
such that they are an integral part of the
neighborhood or the surrounding home sites, are
at an elevation appropriate to their intended
recreational use, have boundaries that are
clearly defined and are accessible to all
neighborhood residents from a public street.
f. Preserve.natural habitat to the maximum
extent possible in a contiguous, connected
configuration. Natural open spaces may include,
but are not limited to, fields, wetlands, slopes,
bluffs, woods, lakes, ponds, streams, shore
lands, and other environmentally sensitive areas.
g. Connect individual home sites with
pedestrian corridors or sidewalks to larger open
spaces and places of destination on and off site.
Open spaces should be accessible to pedestrians
at roughly (1,200) foot intervals along public
roadways. Pedestrian corridors between lots shall
be at least (50) feet in width and buffered from
view of adjacent properties.
h. Buffer residential properties from
incompatible uses with buffer zones of at least
(100) feet to minimize land use conflicts. The
buffer zones shall be thickly planted with native
grasses, shrubs and trees. Roads may be included
in the buffer that will create an effective
barrier separating yards from fields and
pastures.
i. Minimizes development fronting onto
existing arterial roads by establishing buffer
zones with existing and native vegetation to
protect rural roadside character and to improve
public safety and traffic carrying capacity.
j. Locate houses and garages such that the
garages do not dominate the streetscape.
k. Locate septic systems on the most suitable
soils for sub-surface septic disposal.
1. Landscape common areas and street right-of-
ways with native vegetation with high wildlife
conservation value.
F. Density. To calculate the base density for a given
tract:
i. Determine the Eligible Land (See definition).
ii. In the Rl-a zoning district, divide the eligible
land by 2.5 then multiply by 1.15 to determine the
number of lots.
Example:
Eligible land area: 24 acres
Zoning district density: 2.5 acres
OSP density: (24 / 2.5) x 1.15 = 11.04,
or 11 lots
iii. In the A-1 zoning district divide the eligible
land by 10 and multiply by 2.15 to determine the
number of lots.
Example:
Eligible land area:
Zoning district density:
OSP density:
42 acres
10 acres
(42 / 10) x 2.15 =
9.03, or 9 lots
iv. Density bonuses. At the discretion of the City
Council, density bonuses may be permitted which allow
projects to be developed at a density greater than
otherwise allowed provided that one or more of the
following standards are complied with. Each standard
provides an additional density increase above the
allowed zoning district density with a maximum density
increase of 40% above the allowed zoning district base
density.
Example:
Rla District eligible land area - 24 acres
Density bonus: (24/2.5) x .05 = .48
Each 5% bonus = .48 lots
A1 District eligible land area - 42 acres
Density bonus: (42/10) x .05 = .21
Each 5% bonus = .21 lots
a. Creating an endowment to the land trust or
homeowners association where the principal would
generate sufficient annual interest to cover the
conservation easement holder's yearly costs (5%
bonus).
b. Providing for access by the general public
to trails, parks, or other recreational
facilities, excluding golf courses (5% bonus).
c. An additional 10% open space is provided
above the required 50% preserved Eligible Land.
The additional 10% open space shall be buildable
area (5% bonus).
d. Reusing existing buildings and structures
or preserving specific site features inventoried
by the County, City, or State Historical
Preservation Office (5% bonus).
e. Provide covenants to create an
architectural theme to include items such as,
porches, side or rear loaded or detached garages
(5% bonus). Landscape theme, lighting theme, and
open space/central meeting place shall make up
2.5% of the density bonus and additional
architectural elements shall make up 2.5% of the
density bonus. A written narrative describing
the architectural theme shall be provided with
the preliminary plat.
f. Maximum lot size h acre (5% bonus).

Careful siting of each home must seek to fit He topography, protect existing vegetation, views, open
space and other features that define the character of this neighborhood. These guidelines will further
this goal by establishing criteria aimed at achieving quality levels of landscape architecture and sensi-
tive site plans. Our goal is beautiful streetscaFes and open spaces, irtterestin~ and complementary lot
amenity features, paving and planting design. Careful consideration must be made for bature addi-
tions, decks, fences, and screened porches. Consultation with a landscape consultant is recommended
at the early stages of planning.

racy and front yard neighboring opportuni-
ties, while also creating attractive off-lot
impacts and respecting sight lines of other
homes.
2. Respect the existing topography and

3. ARC may require maintenance of sight
lines of other homes to natural or built
amen/ties.
B. TREE PRESERVATION
1. Preserve undergrowth m protected forest
areas. Pathways are appr0pr/ate
2. In concept planning identify the trees you
will be savLng and those that appear to
require removal.

2. On vertical curb streets, utilize existing
curb cut or pay for new location and street
repair.
3. Homes should be positioned with tn
respect to existing homes and tn anticipa-
tion of sitLug of future homes. (See: The
A.R.C. Lot/Home Location Guide.)
D. HOUSE-DOMINANT HOME DESIGNS
1. Reduced setbacks for homes require
design of homes with "tamed garages",
emphasizing a home's elevations and wi~
clear references to building massing and
architectural detailing, including a recog-
nizable style.
E. LIBERTY'S REDUCED SETBACKS
1. 20' setback from property line (15'
from back of most sidewalks) allows
use of deeper floor plans (see City
requirements).
E TAMING THE GARAGE:
1. With reduced lot widths and budget con-
scious home design, house dominant
designs require creative two and three car
garage positioning to screen, dLminish
impact from road, while emphasizing home
entry and approach.
2. Not less than two car or more than four
spaces without ARC approval.
3. Garage positioning that maximizes
house and minimizes garage: ie. · 3 car L-
shaped garages with tandem spaces, turned
garages at side streets, court yard and side
load garages (where lot width permits).

I. GENERAL HOME DESIGN GUIDE
S
Each individual home shall have its own identity and ch.aracter. It will be aesthet4cally balanced, details
consistent with its basic architectural style and be made with quality materials and workmanship.
Homes identical to an established builder's model or portfolio will not be allowed and homes not
demonstrating adequate design variety will not be approved by ARC.

A.~VISUAL IMPACTS
1. Create attractive off-lot visual impacts.
Be mindful of the home's massLng as seen
from surrounding road approaches and in
context with other adjacent and surround
homes. Avoid unaccented 2 & 3 story
facades.
2. Respond to each lot's on and off- site
opportunities to help define the home's
outdoor spaces and guide positions of
home interior spaces
3. Select home design/floor plans that
establish a friendly relationship with the
street via porches, decks, gradual level
changes and anteways, entry sitting areas,
courtyards, patios, terraces, sheltered
entrys, etc.
4. Price efficiency can come with simpler,
lower room count, "box-on-box" floor
plans, blended with modern, shared-space
room layouts.
5. "Stage front" appearance will not be
approved, the sides and rear should sup-
port the style of the home's front eleva-
tions.
6. Camouflage garages with small set-
' backs from home front with porch exten-
sions, arbors, trellises, wing walls or
retaining walls. Use to help hide garbage
& recycle bins.
7. Add steps from garage to home, pro-
vide headroom at garage service door.
Allow space for added risers in garage
and/or transition rooms within home,
such as laundry/mudroom. Design
should reduce impact of blank area above
garage door(s) (ie. lowered roof line,
trim/details.)
