§ 275-104 Dimensional standards.
A.
Permitted uses.
(1)
Minimum developable lot area: one acre. [Note: Refer to Article XI for determination of actual allowable lot size(s); except that tracts of five acres or more with central sewer and water (where the applicable density adjustment factors of Article XI each equal 1.0) may use the standards of Subsection B below.]
(2)
Minimum lot width: 150 feet.
(4)
Maximum building coverage: 15%.
(5)
Maximum building height: 35 feet.
B.
Option (minimum site area of five acres):
(1)
Community facilities. Any site proposed for development under this option shall be served by central water and sewage facilities. (Note: a central water facility utilizing an on-site well or wells shall demonstrate that a sufficient supply will exist to serve the development without causing any adverse effects on the supply available to existing wells in the surrounding area and shall meet all applicable requirements of Chapter 261, Water, Article I, Well Drilling.)
(2)
Density. Density shall be calculated by determining developable area for the site, as provided for in Article XI, and application of the following formula:
T | = | SDA a+b+c+d |
Where: | ||||
T | = | Total number of dwelling units permitted | ||
SDA | = | Site Developable Area | ||
a | = | Proposed % of SFD divided by 2.50 | ||
b | = | Proposed % of two-family divided by 3.50 | ||
c | = | Proposed % of single-family attached divided by 4 | ||
d | = | Proposed % of multifamily divided by 6 | ||
(3)
The following shall determine the number of dwelling units of each dwelling type from the total (T) found in Subsection B(2) of this section.
Number = T x proposed % |
Where: | ||||
N | = | Number of dwelling units of a specific type | ||
T | = | Total number from Subsection B(2) of this section | ||
Proposed % | = | Percentage used for a specific dwelling type in the calculations in Subsection B(2) of this section | ||
(a)
Percentages used in the above calculations shall be in decimal form.
(b)
Regardless of the maximum number of dwelling units permitted in a proposed development based upon Subsection B(2) and (3), a proposed development in an MR District shall conform with all other requirements of this district so that the choice of dwelling types, mixing percentages, natural constraints of a site, or other factors may prescribe a suitable lesser number of dwelling units.
(4)
Dimensional requirements. See Optional Standards Chart as Attachment 1[1] for standards regarding lot area, lot width, building coverage, yard setbacks, and required open space for each dwelling type.
[1]
Editor's Note: Optional Standards Chart is included as an attachment to this chapter.
(5)
Other requirements.
(a)
A single overall plan shall be required, although the plan may be developed in separate phases.
(b)
Any development containing 75 or more dwelling units shall include at least two of the permitted dwelling types, with each type constituting no less than 20% of the total number of units.
(c)
A buffer strip at least 50 feet wide shall be provided along the ultimate right-of-way of all abutting streets and along all tract boundaries. The buffer strip shall include one of the following:
(6)
Additional standards for single-family attached dwellings. In addition to all other applicable standards, no more than eight single-family attached units may be attached in a linear row, provided that in the case of back-to-back units, this limitation shall apply to each of both tiers of units.
