§ 58.511. Development Standards.

In addition to the Zoning District and Use Regulations of Figures 1—2 and the standards ordinarily applying to the review of Master Plan and Subdivision Plat applications, the following standards shall apply:

A.

Development Site Standards:

1.

The development shall meet the requirements of Chapter 65, Part 5D (Improvements Retained in Private Ownership), and Part 5E (Maintenance of Common Improvements and Open Space).

2.

The development shall be designed in a manner to adequately protect adjacent land uses, which shall include for this purpose any landscaped bufferyard which may be required by Chapter 60, Part 2 along the boundaries of the development as necessary to ensure compatibility of land uses, which shall be maintained as common or dedicated open space.

3.

Density for townhome units is calculated as follows:

a)

Maximum density is established by dividing the total number of dwelling units by the net area of the development site.

b)

Minimum density is established by dividing 43,560 square feet by the average size of the individual building sites (townhome lots) in square feet.

4.

Impervious Surface Ratio (ISR): Maximum amount must be established consistent with the applicable zoning district. If the development site is below the maximum ISR, any remaining available impervious surface must be allocated to individual lots as part of the master plan or conditional use permit. ISR in the front and street side setbacks cannot exceed 40%, consistent with Section 61.302(f)(2).

5.

Not more than 8 dwelling units may be provided within a single building.

6.

If the development site includes platting new streets, or includes more than 20 dwellings, in addition to the standard parking requirement in Chapter 61 Figure 26, guest parking is required at a ratio of 1 space per 5 dwellings. On-street parking on streets being constructed within the development site may count toward this requirement.

7.

Development sites with 31 to 99 units must provide a minimum of 2 access points to the surrounding street network. One of these access points may be operated as an "Emergency Only" access and may use a stabilized, pervious surface approved by the City Engineer or designee.

8.

Development sites with 100 or more units must provide a minimum of 2 access points with impervious surfaces suitable for all users.

9.

Front-loaded townhomes are prohibited. Driveway and parking access must be from the rear of the unit.

10.

Driveways must meet the following minimum requirements:

a)

The maximum width is 24 feet at the property line.

b)

Up to four units served: The minimum width is 14 feet at the property line, narrowing to 12 feet at a point 15 feet from the property line.

c)

Five or more units served:

i.

One-way (access to two streets): The minimum width is 14 feet at the property line, narrowing to 12 feet at a point 15 feet from the property line.

ii.

Two-way: The minimum width is 20 feet wide at the property line, narrowing to 16 feet at a point 15 feet from the property line.

11.

Maneuvering areas for perpendicular parking spaces must meet the following requirements:

a)

A minimum of 22 feet clear pavement is required behind each parking space. This 22 feet width may be incorporated into the width of a shared driveway or an alley.

b)

The 22-foot width must be measured from the face of the garage door, the back of a carport, or the back of an uncovered parking space, as applicable.

12.

A minimum 2-foot wide clear area must be maintained adjacent to any backing and maneuvering area that is less than 24 feet wide, and along both sides of the driveways throughout the development site.

a)

This area may be decorative pavement, or landscaped with grass or other groundcover.

b)

This area may not contain a fence, wall or landscaping that includes species with mature heights greater than 18 inches.

c)

This area may only be included in the minimum width of any required bufferyard if it is not paved, and if the required landscaping and/or fences can be accommodated outside the clear area.

B.

Building Site Standards:

1.

Minimum lot width: 20 feet

2.

Minimum area each lot: 1,000 square feet

3.

Setbacks:

a)

For street facing units, each unit must meet the setbacks for the applicable zoning district, except that as part of master plan, a modification to the maximum setbacks in AC and MU districts may be allowed in order to provide a landscaped front yard and/or street side yard.

b)

For units facing a courtyard, the perimeter of the development site must meet the applicable setbacks for the zoning district. Individual units need to meet the front and rear setbacks established by the dimensions for courtyards and driveways.

4.

Height limit: Per the applicable zoning district. Roof decks, whether covered or open air, are included within the height of the building at a minimum height of 8 feet.

5.

Building Separation: A minimum 10-foot separation is required between all buildings on the development site.

6.

Frontage requirements. Each unit must be developed consistent with one of the two following options:

a)

Frontage on a public street, or a private street that meets public street design standards.

b)

Frontage onto a courtyard. The courtyard must include the following:

i.

Minimum width of 15 feet if units face one side of the courtyard. If a bufferyard is required, the courtyard must include sufficient landscaping to meet the bufferyard standard. The 15 feet width courtyard can accommodate up to a 5 foot wide buffer. If a wider bufferyard is required, the width of the courtyard must be increased to meet the bufferyard standard.

ii.

Minimum width of 25 feet if units face both sides of the courtyard.

iii.

Minimum 5 foot sidewalk required for the length of the courtyard. The sidewalk must connect the primary pedestrian entrance of each unit to a sidewalk on a public or private street.

iv.

A maximum of 4 units are allowed on a single-sided courtyard that dead-ends into an adjacent development site. See Figure 7E.

v.

Fencing is not required. If included, fences, walls or other privacy barriers must not block access between individual lots on the side of the building where the primary pedestrian entrances are located.
