§ 19-410. Subdivision design standards: Streets.

All lots and blocks provided in a subdivision shall abut on a street adequate to accommodate all traffic generated, in a reasonable and safe manner. The arrangement, character, extent, width, grade and location of all streets shall conform to all of the elements of the City's "Transportation Plan" and the regulations and City's "Standard Specifications and Construction Drawings" and "Engineering Design Criteria" relating thereto and they shall be designed in accordance with the following provisions:

A.

Each subdivision shall provide for the continuation of all arterials and highways as shown on the adopted Transportation Plan.

B.

Residential development adjacent to an arterial street designated on the Transportation Plan shall comply with the following:

1.

Only backing or siding residential lots shall be used adjacent to the above described roadways unless a frontage road is provided for local access purposes. This shall not apply to any residential lots two (2) acres or more in size.

2.

Steel mesh fencing at least four (4) feet high with permanent evergreen plant screening, at least three (3) feet high, or an opaque fence approved by the City of Norman, shall be installed by the developer within the required screening easement at the right-of-way line behind or at the side of residential lots and shall be maintained by the developer for one (1) year from the date of installation. There shall be no openings in any fence for vehicular access onto the above described roadways except at street intersections, and at approved openings to commercial areas.

3.

Subdivision streets shall not open onto an arterial street except at an average interval of not less than one-quarter (¼) mile, measured from the centerlines.

4.

The maintenance of all required fencing and the arterial right-of-way must be addressed by the developer. Maintenance shall be provided by a mandatory property owners' association or other acceptable arrangement. Such provisions cannot be changed without the express written approval of the City of Norman.

C.

Commercial and industrial subdivisions shall provide access from each parcel to a major street by means of a street system designed for such use, but they shall not have access to residential streets in a manner that encourages or promotes the movement of foreign traffic through residential neighborhoods.

D.

Minor streets shall be laid out so that their use by through traffic will be discouraged.

E.

Collector streets shall be used in the subdivision wherever traffic is being collected from minor streets to provide access to a major street or community facility. Any street shall be deemed a collector street when it serves more than seventy-five (75) dwelling units.

F.

Ingress and egress to multifamily areas having seventy-five (75) or more units shall be provided only on collector streets or frontage roads of appropriate design.

G.

Where a subdivision borders on or contains a railroad right-of-way or limited access highway right-of-way, a street approximately parallel to and on each side of such right-of-way at a distance suitable for the appropriate use of the intervening land may be required. Such distances also shall be determined with due regard for the requirements of approach grades and future grade separation structures.

H.

Reserve strips controlling access to streets shall be prohibited except where their control is placed with the City under conditions approved by the City Council.

I.

A tentative plan of a proposed future street system shall be shown on the preliminary plat.

J.

When a tract is subdivided into larger than normal building lots or parcels, such lots or parcels shall be so arranged as to permit the logical location and opening of future streets and appropriate resubdivision, with provision for adequate utility easements and connections for such resubdivision.

K.

A street crossing another street should continue on the same alignment; however, if it does not, then the off-set shall not be less than one hundred twenty-five (125) feet measured from the street centerlines.

L.

Street right-of-way widths and paving widths shall be in accordance with the Norman Transportation Plan and the Code of the City of Norman.

M.

The grades and the horizontal and vertical alignment for all streets shall be in accordance with the "Engineering Design Criteria" of the City of Norman.

N.

Streets designed for local service only, such as cul-de-sac and loop streets, shall be used to the maximum feasible extent in the subdivision. Streets adjacent to (or separated therefrom only by a single row of lots) public use areas shall be connected thereto with appropriate sidewalks and bicycle paths in dedicated easements.

O.

A cul-de-sac, except for Residential Estates and Norman Rural Certificates of Survey, shall not exceed six hundred (600) feet in length, measured from the centerline of the intersecting street to the center of the turnaround, and if more than one hundred fifty (150) feet in length shall be provided with a circular turnaround having a radius of not less than fifty (50) feet at the property line and not less than forty-two (42) feet at the face in front of the curb. In large lot rural subdivisions, cul-de-sac length shall not exceed twelve hundred (1,200) feet or sixteen (16) lots, whichever is greater.

P.

Half streets shall be prohibited.

Q.

The arrangement of streets shall be such as to cause no undue hardship either on a subdivider or in the subdividing of adjacent properties. The dedication of street rights-of-way to facilitate the development of adjoining properties may be required.

R.

No street names shall be used which will duplicate or be confused with the names of existing streets. Street names and house numbers shall be assigned in accordance with the City system and shall be subject to approval of the Public Works Department.

S.

Vehicular entrances to commercially or industrially zoned or used areas shall conform to Section 9.9 of Oklahoma Department of Transportation's (ODOT's) "Roadway Design Manual." Specific variations from this policy may be approved by the City Engineer.

T.

Street intersection design, including sight distance and right-of-way, shall be in accordance with the City's "Engineering Design Criteria".
