§ 19.15.080. Street length.

A.

Length of a block or street segment. The maximum length of any block or street segment (including a looped street) shall be one thousand six hundred feet along arterial streets, except that where lots are designed under Section 19.15.060 F.4. blocks may not exceed eight hundred feet. Block faces shall not exceed one thousand feet along other streets and the full perimeter of a block shall not exceed two thousand four hundred feet except when Table 19.15-3 specifies otherwise or where topographic features or parcels of one-half acre or larger would justify an exception from this requirement. Cul-de-sac streets shall adhere to Table 19.15-1 or other requirements herein. Measurements shall be as measured along the centerline of the street from the centerline or center point of one intersection to the centerline or center point of the next intersection. For the purposes of measurement, either a full four-way intersection or a "T" three-way intersection shall be considered an intersection. Traffic calming may be provided by the developer or may be required in accordance with the adopted Neighborhood Management Policy and in accordance with the DSC by the city manager or designee.

The length of a block or street segment may exceed the maximum length stated in paragraph A. above under the following conditions:

1.

Blocks containing retention or detention ponds;

2.

Blocks containing parks, and

3.

Development where the proposed development abuts the rear of an existing development and no rights of way have been provided.

B.

Maximum Length of a Cul-De-Sac Street.

1.

No cul-de-sac served by one access point in any single-family, multiple-family, industrial, or commercial subdivision shall exceed six hundred feet in length or the length as shown in Table 19.15-1, whichever is less.

2.

No cul-de-sac in any single-family subdivision district shall be designed to serve more than twenty-five single-family dwelling units, unless an exception is granted by the CPC to the maximum length, in which case the maximum number of dwelling units shall be increased in the same percentage as the maximum length has been increased.

3.

For purposes of this paragraph, cul-de-sac length shall be measured along the centerline of the cul-de-sac from a point beginning at the intersection of the cul-de-sac street with the centerline of the street from which it extends to the center of the turnaround at the end of such cul-de-sac. (Also see Section 19.15.090 for cul-de-sac requirements.) For the purposes of measurement, either a full four-way intersection or a "T" three-way intersection shall be considered an intersection.

4.

An exception may be granted by the city plan commission to develop a parcel:

a.

With topographic problems;

b.

With Arroyos or environmental areas requiring protection surrounding such parcel;

c.

That is effectively landlocked with no other alternative than a cul-de-sac exceeding six hundred feet;

d.

Is in a proposed subdivision that has such a unique configuration that the only way to serve the area in question is with a cul-de-sac exceeding six hundred feet. Such exception shall not be granted if the length of the cul-de-sac can be reduced by connection to an adjacent and/or parallel street. The desire to gain additional lots from the cul-de-sac exception by itself is not reason enough to grant such exception to the maximum length;

e.

Additional modifications may be required by the city plan commission upon recommendation by the fire marshall's office including intermediate turnarounds (eyebrows) to accommodate emergency vehicles being provided at a maximum distance of six hundred feet;

f.

Building construction within the area of the cul-de-sac beyond the six hundred feet distance shall be fire sprinklered and a note shall be added to the recording plat and the subdivision improvement plans indicating that buildings are required to be sprinklered within the subdivision, and which lot numbers have such requirement.

C.

Cross-Reference. Also see Section 19.15.090 below for cul-de-sac requirements.
