Conformance to thoroughfare plan.
The arrangement, character, extent, width, grade, and location of all major streets shall conform to the current City of Lubbock Master Thoroughfare Plan.
c. 
Street layout.
New and substantially improved streets in a subdivision shall be planned and laid out in accordance with the following standards.
1. 
General design. Streets shall be designed to integrate as much as possible with the topography and natural resources of the site, to discourage the use of through-traffic where inappropriate considering the character of the area, to permit efficient drainage and utility systems, and to require the minimum number of streets necessary for the convenient and safe access to property.
2. 
External access points. Streets shall be arranged in such a manner as to cause no hardship in the subdividing of adjacent properties with external access points provided in accordance with Subsection d, Access, below.
3. 
Internal connectivity. Street patterns in the SF-1 and SF-2 district may be of a radial design consisting of curvilinear streets, cul-de-sacs, and/or U-shaped streets. Street patterns in the HDR and Base Mixed-Use districts shall consist of an interconnected grid network. Streets in a master planned or commercial setting may consist of a mix of such designs.
4. 
Future streets. Lots shall be so arranged as to permit the logical location and opening of future streets, consistent with the current City of Lubbock Master Thoroughfare Plan.
5. 
Abutting streets. Each subdivision shall provide for the continuation of all abutting streets.
6. 
Extension to boundary.
A. 
Unless waived by the City Engineer, proposed streets within a subdivision shall extend to the boundary lines of the tract to be subdivided without the use of reserve strips, as prohibited in Subsection l, Reserve Strips, below. The City Engineer may require a temporary turnaround at the end of such stubbed streets, pending their extension, where such turnarounds appear necessary to facilitate the flow of traffic or accommodate emergency or service vehicles.
B. 
A barricade shall be required for all stub streets.
C. 
A turnaround shall have a paved radius as required in 39.04.005.h, Cul-de-Sacs, below, or be of such other design approved by the City Engineer. A stubbed street shall be a maximum of 400 feet in length measured from the nearest right-of-way line of the intersecting street, along the centerline of the street, to the center of the turnaround. Stubbed streets with temporary turnarounds that are greater than 400 feet in length shall comply with the standards in Subsection h, Cul-de-Sacs, below.
7. 
Traffic generation. All streets shall be designed based on the City's Engineering Minimum Design Standards and Specifications and Thoroughfare Plan.
8. 
Nonresidential development. In nonresidential developments, the arrangement of streets and other accessways shall consider the arrangement of lots, the location of rail facilities, the provision of alleys, truck loading and maneuvering areas, pedestrian movements, and parking areas so as to minimize conflicting movements between the various types of traffic, including pedestrians.
9. 
Dedication. If a portion of a street designated on the current City of Lubbock Master Thoroughfare Plan is located within the proposed subdivision, the total required right-of-way width shall be dedicated. If such street is located adjacent to the outer edge of the subdivision, the amount of right-of-way to be dedicated shall be determined by the proposed alignment of the thoroughfare, and in most cases, no less than one-half of the required right-of-way.
10. 
Half-streets. The dedication of half-streets is only permitted where a subdivision adjoins undeveloped property and a Collector A, Collector B, Minor Arterial A, Minor Arterial B, Principal Arterial A, or Principal Arterial (Modified) as shown on the current City of Lubbock Master Thoroughfare Plan for the perimeter of the property or as needed for half width construction. Wherever a half-street is adjacent to an unsubdivided tract, the other half of the street shall be dedicated when the adjacent tract is platted. Approval by the City Engineer shall be required for half-width paving where full width dedication exists.
11. 
TxDOT approval. Any access to TxDOT rights-of-way shall be subject to approval by TxDOT.
12. 
Circulation. Circulation shall take place in a new subdivision according to the following standards.
A. 
Perimeter arterials. Arterial streets shall generally not be located within a residential subdivision. They may only be located on the perimeters of a residential subdivision. A residential subdivision shall not be located adjacent to a freeway unless the subdivider provides a screening wall that abates noise to the satisfaction of the City Engineer. Such screening wall shall be located, owned, and maintained on property owned by the homeowners' or property owners' association or publicly owned and maintained under appropriate mechanisms as may be approved by the City (such as PIDs). For a nonresidential parcel or tract located adjacent to a freeway, the following shall apply:
i. 
If an existing arterial accesses the freeway, the parcel or tract shall take access from such arterial.
ii. 
If no arterial access is available, access to the expressway shall be provided by a collector street. No local street shall have direct access to an expressway other than to a frontage or access road.
B. 
Local street conversion. New subdivisions shall be designed so that future development shall not require the conversion of local streets to collector streets or arterial streets.
13. 
Thoroughfares. Whenever a subdivision includes a street which, according to the current City of Lubbock Master Thoroughfare Plan requires an ultimate cross-section with a higher functional classification than a collector street, the developer shall:
A. 
Right-of-way dedication. Dedicate the right-of-way required by the Thoroughfare Plan and the Bicycle Master Plan for an arterial street; and
B. 
Street construction. Construct their portion of the arterial street, install curb and gutter along the arterial adjacent to the site perimeter, or be assessed the required impact fee as may be provided for under Chapter 41, Impact Fees, of the City of Lubbock Code of Ordinances.
d. 
Access.
1. 
Intent. The intent of this Subsection is to provide for adequate spacing between driveways, cross-streets, median openings, and signalized intersections by:
A. 
Promoting consistent and suitable traffic flows and speeds by establishing appropriate and uniform spacing;
B. 
Decreasing the density of access points to limit conflicts and improve safety;
C. 
Maintaining safe distances between access points to provide appropriate stopping, intersection, and decision sight distances; and
D. 
Avoiding the functional areas of interchanges and intersections to the extent practical to limit conflicts and maintain capacity.
2. 
Connection spacing requirements.
A. 
Minimum spacing. Access connection spacing criteria for all new or modified street and access connections to thoroughfares (collectors and arterials as designated by the Master Thoroughfare Plan) in the City of Lubbock shall meet or exceed the minimum connection spacing requirements provided in Table 39.04.005-1, Minimum Connection Spacing by Street Classification, and shown in Figure 39.04.005-1, Minimum Driveway and Access Connection Spacing, except as noted below.

Figure 39.04.005-1
Minimum Driveway and Access Connection Spacing
B. 
Desirable spacing. While the minimum distances are required to maintain safe and efficient traffic flow, the typical Lubbock one-mile grid may be configured with additional space between connections. Additional spacing which is beyond the minimums is not required but is desired by the City. As an example, the desirable spacing of driveways, median openings, and traffic signals along the typical one-mile grid is shown in Figure 39.04.005-2, Desirable Driveway and Access Connection Spacing for Arterials.
C. 
Measuring spacing distances.
i. 
Distance D is measured along the edge of the traveled way from the closest edge of pavement of the first access connection to the closest edge of pavement of the second access connection.
ii. 
Connection spacing distances shown in the table must be measured between the endpoints shown in the figure.
iii. 
The remaining distances are measured center to center.
Figure 39.04.005-2
Desirable Driveway and Access Connection Spacing for Arterials
D. 
Strategies to reach minimum spacing. Joint-access driveways, cross-access connections, and public access easements are some of the strategies that can be used to avoid violating these minimum spacing requirements. Refer to Section 39.04.010, Easements, for joint access and cross-access standards.
E. 
Alternative compliance standards for constrained properties. The intent of access management is to meet the minimum or desired access spacing. However, some circumstances may exist in which the minimum access spacing cannot be met due to the size and location of a property. In these cases, the property is not to be denied access, but shall meet the below standards, as applicable.
i. 
Nonresidential driveways. Driveways for constrained nonresidential properties shall meet the following standards:
a. 
One driveway may be permitted within the first 100 feet of frontage. Properties with 300 feet of frontage or more may be allowed additional drives per 200 feet of frontage.
b. 
Driveways are not allowed within 150 feet approaching an arterial-arterial intersection or within 100 feet exiting the intersection.
c. 
In the case of nonresidential driveways along arterials, Figure 39.04.005-3, Nonresidential Driveway Allowances in Constrained Circumstances, lists the number of driveways a nonresidential property is allowed under constrained circumstances.
d. 
In the event none of the alternative compliance methods can be achieved, a property owner may apply for a Variance from the Zoning Board of Adjustments (ZBA) in accordance with Section 39.07.037, Variance.
Figure 39.04.005-3
Nonresidential Driveway Allowances in Constrained Circumstances
ii. 
Single-family detached driveways. Driveways for constrained properties with single-family detached dwellings on local roads shall meet the standards for the number of driveways per property provided in Table 39.04.005-2 Single-Family Detached Driveway Guidelines.

3. 
Driveway throat length. Table 39.04.005-3, Minimum Driveway Throat Length, lists the minimum driveway throat length that shall be provided to allow traffic entering the site to be stored on-site without affecting traffic flow on the abutting roadway. Driveway throat length is defined as the distance from the edge of the arterial street to the first point of conflict in the driveway and is based on the anticipated number of parking spaces. Exceptions to the minimum throat length standards will require a queuing analysis based on anticipated site trip generation and approval of the City Engineer. The length of multiple throats may be combined to meet the standard. For example, a 100-space parking lot with two driveways could allow for two 25-foot throats.

B. 
New developments building collector facilities are required to align with existing collectors, if possible, except in the following circumstances and with approval of the City Engineer:
i. 
Physical constraints such as playa lakes;
ii. 
Areas where discontinuous facilities are desired as a traffic calming measure; or
iii. 
A Master Thoroughfare Plan amendment is formally filed and approved.
C. 
Collectors must include pedestrian facilities on both sides in accordance with City's Engineering Minimum Design Standards and Specifications; and
