The widths, lengths and shapes of blocks shall be suited to
the planned use of the land, zoning requirements, need for convenient
access, control and safety of street traffic, topography, and solar
access.
A. The lengths of blocks in residential areas shall not as a general
rule be less than 600 feet nor more than 1,500 feet in length unless
otherwise dictated by exceptional topography or other limiting factors
of good design.
B. Pedestrianways of not more than 10 feet in width may be required
where deemed necessary by the City Plan Commission to provide safe
and convenient pedestrian circulation between the individual lots,
streams, lake shores, park lands or other public areas or may be required
near the center and entirely across any block where deemed essential
by the City Plan Commission to provide adequate pedestrian circulation
or access to schools, shopping centers, churches, parks, open spaces,
or transportation facilities. The final plat shall contain a special
restriction addressing by whom mid-block pedestrianways will be maintained.
C. The width of blocks shall be wide enough to provide for two tiers
of lots of appropriate depth, except where otherwise required to separate
residential development from through traffic. Width of lots or parcels
reserved or laid out for commercial or industrial use shall be adequate
to provide for off-street service and parking required by the use
contemplated and the area zoning restrictions for such use.
D. Utility easements shall, where practical, be placed on mid-block
easements along rear lot lines.
The size, shape and orientation of lots shall be appropriate
for the location of the subdivision and for the type of development
and use contemplated. The lots should be designed to provide an aesthetically
pleasing building site and a proper architectural setting, and for
solar access for the building contemplated. In addition:
A. Lines. Side lot lines shall be at right angles to straight street
lines or radial to curved street lines on which the lots face. Lot
lines shall follow municipal boundary lines rather than cross them.
B. Double frontage and reverse frontage. Double frontage and reverse
frontage lots shall be prohibited except where necessary to provide
separation of residential development from through traffic or to overcome
specific disadvantages of topography and orientation.
C. Access. Every lot shall front or abut for a distance of a least 80
feet on a public street/right-of-way and be at least 45 feet on all
proposed culs-de-sac.
[Amended 4-18-2013 by Ord. No. 1371]
D. Area and dimensions. Area and dimensions of all lots shall conform
to the requirements of the City Zoning Code or zoning ordinance of
the jurisdiction where the land division occurs, except that land
divisions which occur within the ERS Existing Suburban Residence Districts
or RL Lakeshore Residence Districts shall conform to the area and
dimension requirements of a new conforming district appropriate to
the surroundings as approved by the Plan Commission and Common Council.
The Common Council determines these provisions are necessary to preserve
the public health, safety, and morals because:
(1) The area and dimensions provided for the ERS and RL Zoning Districts
were intended to accommodate the nature of existing developments,
the majority of which pre-date the establishment of zoning codes.
The area and dimensions provided by these districts are not intended
to perpetuate high-density development opportunities.
(2) The provisions of the ERS Existing Suburban Residence Districts or
RL Lakeshore Residence Districts would otherwise permit high-density
development opportunities which are in conflict with the adopted comprehensive
plans, which call for residential densities not to exceed 2.9 dwelling
units per acre on lots of 15,000 square feet. The allowance for lots
of 10,000 square feet in the RL District and 11,250 square feet in
the ERS District has the effect of raising permitted densities to
unacceptable levels.
(3) In addition to the area and dimension requirements above, those building
sites not served by a public sanitary sewer system or other approved
systems shall be sufficient to permit the use of an on-site soil absorption
sewage disposal system designed in accordance with Ch. SPS 383, Wis.
Adm. Code, and administered by Waukesha County.
E. Resubdivision. Whenever a tract is subdivided into parcels five acres or less in area and more than twice the minimum lot area required for the zoning district in which such parcel is located, the Plan Commission may require such parcels to be arranged and dimensioned so as to allow resubdivision of any such parcels in accordance with the provisions of this chapter and in conformance with Chapter
400, Zoning, of the City Code or County Zoning Ordinance.
F. Depth. Depth of lots shall be a minimum of 100 feet. Excessive depth
in relation to width shall be avoided and a proportion of two to one
shall be considered a desirable ratio under normal conditions. Depth
and width of lots or parcels reserved or laid out for commercial or
industrial use shall be adequate to provide for off-street service
and parking required by the use contemplated and the zoning restrictions
for such use.
G. Extra depth. Double frontage and reverse frontage lots, where permitted
to provide separation of residential development from through traffic
or to overcome specific disadvantages of topography and orientation,
shall provide an extra lot depth of 30 feet or landscaped buffering
unless a greater depth is specified herein.
H. Water's edge. Lands lying between the meander line and the water's
edge and any otherwise unplattable lands which lie between a proposed
subdivision and the water's edge shall be included as part of lots,
outlots or public dedications in any plat abutting a stream or lake.
I. Width. Width of lots shall conform to the requirements of Chapter
400, Zoning, or other applicable ordinance, and in no case shall a lot be less than 80 feet in width at the setback line for that specific zoning district.
[Amended 4-18-2013 by Ord. No. 1371]
J. Corner lots. Corner lots shall be designed and platted with at least
10 feet of extra width over and above the minimum required for the
zoning district wherein located to permit adequate building setbacks
from side streets, and access shall be restricted to the minor street.
K. The shape of lots shall generally be rectangular, with lots platted
on culs-de-sac generally narrower at the street line than at the rear
lot line.
Special restrictions which are appropriate to the location or
design of the land division may be required by the Plan Commission
and shall be shown on the final plat or certified survey map. Examples
of the application of this provision include access control along
public ways, required planting and buffering strips, and prohibition
of structures and vegetative clearing in environmentally significant
lands.
