The maximum residential density shall not exceed twenty (20) units per acre.

(3)

Townhouse performance standards. The townhouse performance standards are intended to offer high-quality design in development as a fee simple alternative to conventional single family development.

a.

Pedestrian and bicycle circulation. Pedestrian and bicycle circulation within the NR district shall be designed to accommodate pedestrians and bicyclists in a safe and convenient manner on development and redevelopment sites.

1.

Commercial site plans shall depict stub-outs to adjacent parcels to accommodate future development or redevelopment activity and shall be reviewed by the county engineer. Where stub-outs are adjacent to parcels for which commercial site plans are under review, these plans shall depict connections to existing stub-outs. With these connections, commercial site plans are exempt from the landscaping requirements of section 24-4(a)(2).

2.

Developments that use shared driveways between adjacent parcels may be permitted to reduce fifteen (15) percent of the total off-street parking required on both parcels as specified in section 38-1476. This incentive may not be combined with any other off-street parking reduction specified in this section.

3.

Consistent with the intent of this section, access management shall not be pursued using street closures or cul-de-sacs.

4.

Waivers from these regulations shall be addressed by the development review committee (DRC).

c.

Parking. Parking facilities and ratios shall be designed to avoid disruption of the urban development pattern with parking areas and to promote safe and convenient pedestrian access and circulation. Parking shall be consistent with the requirements of article XI of this chapter and the landscaping requirements of chapter 24, with the following exceptions:

1.

A fifteen (15) percent increase to the criteria established for the calculation of the minimum parking requirements specified in section 38-1476 shall be considered the maximum parking allowable on a development site.

2.

Parking areas in front of buildings shall be limited to one aisle of parking spaces, with additional required parking to be provided on the side or rear of buildings or in shared parking areas.

3.

Sharing of off-street parking between land uses shall be encouraged by reducing the total number of parking spaces required for all land uses by fifteen (15) percent.

Additional parking reductions may be available upon submittal of a parking study by a qualified transportation engineer to the zoning manager demonstrating no adverse impacts to the surrounding area from parking reductions and demonstrating consistency with shared parking methodologies available from the Urban Land Institute. The zoning manager must approve any additional proposed reductions in parking.

4.

To promote the use of alternative modes of transportation in a manner compatible with an urban development pattern, a minimum of two bicycle parking spaces shall be provided where ten (10) or more vehicular parking spaces are required, with additional bicycle parking spaces required at a ratio of one bicycle parking space for every ten (10) vehicular parking spaces. No more than fifteen (15) bicycle spaces are required in any case.

(5)
