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; Case Nos.
