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.

the site.
•Noting the applicant’s willingness to also include in their application with respect
