§ 61.221. General Requirements.

All streets shall be designed in accordance with the specifications of Figure 5 and the following:

Connectivity with Surrounding Street Network. The street layout and site circulation of all new developments shall be coordinated with and interconnected to the street system of the surrounding area. Streets in all new developments, including all new subdivisions, shall be connected to platted streets in adjacent areas wherever feasible and deemed necessary by the City, to allow for property inter-neighborhood traffic flow and proper connectivity for all modes of transportation, including, but not limited to, walking, biking, and transit by conforming with the following:

(a)

Interconnected Street Network. The development shall provide multiple direct vehicular and pedestrian connections in its local street system and internal circulation to and between nearby local destinations, such as transit stops, parks, schools, residences, workplaces and shops, without requiring the use of arterial streets. Each development shall incorporate and continue all collector or local streets stubbed to the boundary of the development plan by existing development or previously approved but un-built development.

(b)

Maximum Block Size. The development shall provide a local street connection spaced at intervals not to exceed 660 feet along each boundary that abuts potentially developable or redevelopable land. On each boundary of less than 660 feet a vehicular and pedestrian cross-access easement shall be dedicated to the benefit of the neighboring property.

(c)

Minimum Accessibility. The development shall provide a potentially signalized, full-movement intersection of a collector or a local street with arterial street at an interval of at least every 1,320 feet or one-quarter mile along arterial streets. The development shall provide additional non-signalized, potentially limited movement, intersections of a collector or local street with an arterial street at intervals not to exceed 660 feet between each full movement collector and local street intersection. Development whose dimensions are less than 660 feet adjacent to arterial streets shall provide two points of ingress/egress wherever the development comprises 30 residential units or more, and all non-residential development shall provide vehicular and pedestrian cross access easements and facilities to any adjacent property that co-terminates with any arterial facility. Traffic signals shall be required when warranted.

(d)

Street Stub-Outs to Abutting Properties. Wherever the development abuts unplatted land or a future development phase of the same development, street stubs shall be provided in accordance with the requirements of this Section to provide access to abutting properties or to logically extend the street system into the surrounding area. Street stubs are to be named in accordance with the street name policy. All street stubs shall be provided with temporary turn-arounds or cul-de-sacs unless specifically exempted by the Public Works Director, and the restoration and extension of the street shall be the responsibility of any future developer of the abutting land.

(e)

Connectivity Index Requirement. In addition to paragraphs (b) and (c) above, a proposed development shall provide a minimum connectivity ratio of 1.4 (links over nodes), where each street and cul-de-sac is counted as one link, and each intersection and end of a cul-de-sac is counted as one node.

(f)

Access Management. The City Transportation Engineer may require any limited movement collector or local street intersections to include an access control median or other acceptable access control device consistent with Chapter 61.

(g)

Exemption. The requirements of paragraph (a), (b), and (c) above may be waived if, in the written opinion and analysis of the City Transportation Engineer or Planning Official, they are infeasible due to unusual topographic features, existing development, or a natural area or feature.

(h)

Gated Subdivisions and Development. Gated public and private street entryways are prohibited. However, gated entryways to any surface parking area outside the Traditional City for multi-family development are permitted.

(i)

Cul-De-Sac Pedestrian Connections. Except for industrial properties, the development shall dedicate to the public an improved 15-foot wide pedestrian and bicycle access connecting to the termination of all cul-de-sac streets, or passing through odd-shaped or oversized city blocks over 660 feet or longer, in order to complete existing pedestrian and bicycle routes and to provide for networks of public paths creating access to schools, parks, transit stops, arterial street networks or other destinations. This requirement may be waived by the Planning Official where impracticable.

Location of Street Centerlines. The location of the centerlines of all existing street rights-of-way shall be as determined by the Public Works Director.
