SUMMARY
This ordinance amendment is a critical step in the process of developing zoning strategies for development of
land with important sensitive or unique natural features that may be vulnerable in the context of urban
development. The zoning ordinance already has an RL Low Density Residential District which requires 20,000
sq. ft. lots. However, Staff believes that modifications are needed to achieve the preservation of natural features
in addition to encouraging large house construction on large lots. The basic strategy is to have a zoning district
with a low overall density ceiling,but allow clusters or pockets of moderate density development within the
district to create larger opportunities for preserved land.
The other important consideration is that because of the overall very low density within the RL district, other
adjacent districts may be expected to absorb density in order to negotiate with developers (and avoid legal
challenges of"takings").
,
On October 14, 1997, the Planning Commission conducted a public hearing as required for the amendment.
While no mailing occurred, ten to fifteen residents attended from the Danbury Way neighborhood to discuss the
amendment. Comments where generally related to potential development of the Kelley Trust property which
may be partially rezoned to RL. The Planning Commission was generally in favor of the amendment with one i
additional reference to wildlife to be added to the language. One Commissioner felt that the cluster areas should
have a density ceiling of 2 units per acre instead of 2.5. However, the Commission adopted a motion to
recommend approval(4-1)based upon the 2.5 dwelling unit(net)maximum within the cluster areas. Staff has
modified the PUD section for clarity and will provide a revision based upon comrnents from the City Attorney
as necessary.
RECOMMENDED ACTION: Motion to adopt the zoning ordinance text amendment for the RL Very
Low Density Residential District.

THE CITY COUNCIL OF THE CITY OF ROSEMOUNT, MINNESOTA, ORDAINS AS
FOLLOWS:
Section 1. Section 6 of Ordinance B-City of Rosemount Zoning Ordinance, adopted September
19, 1989, is hereby amended to include:
6.4 RL VERY LOW DENSITY SINGLE-FAMILY RESIDENTIAL DISTRICT:
A. Purpose and Intent: The purpose of this District is to allow low density residential
development within the Metropolitan Urban Service Area while minimizing negative
environmental impacts on areas with greatest physical arnenities (rolling topography, forest,
wildlife habitat,water bodies). Single-Family Detached Dwelling Cluster Development will
be encouraged as a tool to protect unique physical features and restrict development to the
most suitable locations. The twenty thousand(20,000} square foot minimum lot size will
accommodate larger homes than the R-1 (10,000 square foot minimum lot size)District,
will mandate increased structure separation and will allow for more selective siting of
homes. The lower maximum density of one dwelling unit per acre will result in
preservation of natural amenities within the context of providing urban services.

1. Essential Service Facilities except electrical substations and switching stations.
2. Licensed Child Day Care, for twelve(12)or fewer persons. Unlicensed facilities
