All monuments shall be in accordance with § 236.15,
Wis. Stats.
The arrangement, character, extent, width, grade,
and location of all streets shall conform to the Comprehensive Plan
and to these regulations and shall be considered in their relation
to existing and planned streets, to reasonable circulation of traffic,
to topographical conditions, to runoff of stormwater, and to public
convenience and safety and in their appropriate relation to the proposed

Continuation of existing streets. The arrangement
of streets in new subdivisions shall make provision for the appropriate
continuation at the same width of the existing streets in adjoining
area wherever topographic and other physical conditions permit.
B.

are not subdivided but may be subdivided, the arrangement of streets
in a new subdivision shall make provision for the proper projection
of streets into adjoining areas by carrying the new streets to the
boundaries of the new subdivision at appropriate locations.
C.
Blocks. Block length and width or acreage within bounding
streets shall be such as to accommodate the size of residential lots
required in the area by the Zoning Code and to provide for convenient
access, circulation control, and safety of street traffic. Blocks
shall be appropriate for the topography and the type of development
contemplated.

on a publicly dedicated street to allow vehicular access.
B.

at right angles to the street lines.
G.
Watercourses. Lots abutting upon a watercourse, drainageway,
channel or stream shall have an additional depth or width as required
to assure house sites that are not subject to flooding.
H.
Access. In the platting of small tracts of land fronting
on limited access highways or thoroughfares where there is no other
alternative, a temporary entrance may be granted. As neighboring land
becomes subdivided and more preferable access arrangements become
possible, such temporary access permits shall become void.
I.
Through or double frontage lots. Such lots shall not
be permitted except where such lots back onto a highway or arterial;
such lots shall have additional depth of 10 feet for screen planting

an existing or planned major thoroughfare or a railroad right-of-way,
a street approximately parallel to and on each side of such right-of-way
for adequate protection of residential properties and to afford separation
of through and local traffic may be required. Such service streets
shall be located at a distance from the major thoroughfare or railroad
right-of-way suitable for the appropriate use of the intervening land,
