Requested Modifications to Subdivision Ord.
1)Subdivision Ordinance No. 483, as amended, Section 5.04 does
not permit private streets in new subdivisions in which less than
75% of the lots contain homeowner occupied structures. The
applicant is requesting a gated community with private streets
with the initial development.
2) Subdivision Ordinance No. 483, as amended, Section 5.03.I -
Generally, a maximum number of twenty (20) dwelling units
should be permitted on a cul-de-sac street permanently designed
as such. Additionally, the length of the Cul-de-Sac should not
exceed 1,000 feet or be less than 150 feet in length. However,
density of development, topography, lot sizes and other
significant factors will be weighed in determining the length of a
cul-de-sac street.
3) Subdivision Ordinance No. 483, as amended, Section 5.03.K states
that dead end streets shall be permitted only where a future
extension or connection is to be made. The applicant has
removed the connection to the street stub from the Siena
subdivision to the south.
October 5, 2017; Tabled to the October 19, 2017 meeting (6-0).
October 19, 2017; Approved (4-2) subject to the Staff Report dated October 19, 2017;
further subject to the Development Plan Review Summary No. 4 dated October 19,
2017;
•Granting the variance No. 1 related to a gated community on the northern end and
variance No. 2 on the length of the cul-de-sac street; specifically not granting
variance No. 3 related to gated emergency access only on the southern side of
the site.
•Noting the applicant’s willingness to also include in their application with respect
to alleyways an alternative that does not include alleyways in the Site Plan.
•Noting the applicant’s willingness to provide alternative Site Plans relative to
access to the site for Council’s consideration.

February 20, 2018; Approved at 1st reading (5-2) subject to the staff report dated February 13, 2018 and
Development Plan Review Summary No. 8, dated February 13, 2018 noting the following approvals of the
modifications to Subdivision Ord. No. 483 as requested:
1) Subdivision Ordinance No. 483, as amended, Section 5.04 does not permit private streets in new subdivisions
in which less than 75% of the lots contain homeowner occupied structures. The applicant is requesting a
variance to allow a gated community with private streets with the initial development of the subdivision.
2) Subdivision Ordinance No. 483, as amended, Section 5.03.I - Generally, a maximum number of twenty (20)
dwelling units should be permitted on a cul-de-sac street permanently designed as such. Additionally, the
length of the Cul-de-Sac should not exceed 1,000 feet or be less than 150 feet in length. This proposed plan
does not meet the intent of the regulation, however, noting that a secondary emergency only access to the
subdivision has been provided.
3) Subdivision Ordinance No. 483, as amended, Section 5.03.K states that dead end streets shall be permitted
only where a future extension or connection is to be made. The applicant has removed the connection to the
street stub to the Siena subdivision to the south,
Also noting the applicant’s willingness to address the stacking distance issues on egress and ingress as it relates to
where the gate is positioned and will come to 2nd reading with an option or options for City Council to consider,
And then noting that Council would be directing staff that in order for the applicant to obtain a first lot certificate of
occupancy, they’ll be required to have completed the open space and water features prior to that issuance of a CO.
