Burbank Municipal Code Art. 10 Street Design (CA)

11-1-1001: ARTERIAL AND COLLECTOR STREETS:

Arterial and collector streets shall conform to the following requirements:

A. Alignment of Streets: Alignment shall be substantially an extension of existing streets in the City modified only to fit conditions of terrain and purpose, in conformance with this article.

B. Centerline Curve Radius of Streets: The centerline curve radius shall be not less than:

One thousand five hundred feet (1,500') on arterial streets in nonmountainous areas.
One thousand feet (1,000') on collector streets in nonmountainous areas.
Three hundred feet (300') on arterial and collector streets in mountainous areas if reduction below the limits for nonmountainous areas is approved by the Public Works Director. [Formerly numbered Section 27-101; renumbered by Ord. No. 3058, eff. 2/21/87; 2197.]

11-1-1002: PART WIDTH ARTERIAL AND COLLECTOR STREETS:

Part width arterial and collector streets, and reservations of easements therefor, lying along and abutting the subdivision boundary shall have such width as will conform to existing streets or to future extensions of such streets in conformance with this article. [Formerly numbered Section 27-102; renumbered by Ord. No. 3058, eff. 2/21/87; 2197.]

11-1-1003: STREET LAYOUT TO CONFORM TO GRADE SEPARATIONS:

The street layout of arterial and collector streets shall conform to the City’s grade separation plan at crossings of railroad and rapid transit rights of way if the General Plan provides for a grade separation. [Formerly numbered Section 27-103; renumbered by Ord. No. 3058, eff. 2/21/87; 2197.]

11-1-1004: BRIDGE APPROACHES:

Subdivision of land abutting an approach to an existing or proposed bridge shall be arranged so that the street layout adequately provides for the approach. [Formerly numbered Section 27-104; renumbered by Ord. No. 3058, eff. 2/21/87; 2197.]

11-1-1005: LOCAL STREETS:

Local Streets shall conform to the following requirements:

A. Street System: The street system shall relate to existing streets in the area adjoining the subdivision, shall as far as practicable be in alignment with existing adjacent streets or their proper projection, and shall be in general conformity with the General Plan; provided that in cases where the holdings are large enough, a modified curved street layout may be required or permitted if such layout will not interfere with the general street plan. Boundary connections to adjoining unsubdivided property may be required.

B. Cul-De-Sac Streets: Cul-de-Sac streets shall not exceed five hundred feet (500') in length and shall be provided with a turning area at the terminus thereof with a minimum right of way radius of forty feet (40').

C. Curved Streets: Curved streets shall have a centerline radius of not less than two hundred fifty feet (250') wherever practicable. Reverse curves shall be separated by a minimum one hundred foot (100') tangent section except when otherwise approved by the Public Works Director.

D. Dead End Streets: Dead end streets and alleys shall be avoided unless approved by the Public Works Director. If approved, adequate provision shall be made at the end of the street or alley for drainage and a turning area with a minimum roadway radius of thirty five feet (35') and a minimum right of way radius of forty feet (40'). [Formerly numbered Section 27-105; renumbered by Ord. No. 3058, eff. 2/21/87; 2197.]

11-1-1006: STREET INTERSECTIONS:

Streets shall intersect at as nearly a right angle as is practicable. The block corners in residential districts shall be rounded at the property line by a radius of not less than fifteen feet (15'), and in commercial districts or on lots adjacent to a collector or arterial street by a radius of not less than twenty feet (20'). A suitable diagonal cutoff equivalent to rounding the block corner may be permitted. [Formerly numbered Section 27-106; renumbered by Ord. No. 3058, eff. 2/21/87; 2197.]

11-1-1007: FUTURE STREETS:

Future streets and alleys shall be provided where it is determined that a street or alley is necessary for the future subdivision of the property being subdivided or adjoining property. Future street strip lots may be required at the terminus of dead end streets and along that portion of a street being dedicated on a partial width basis. [Formerly numbered Section 27-107; renumbered by Ord. No. 3058, eff. 2/21/87; 2197.]

11-1-1008: STREET GRADES:

No arterial or collector street shall have a grade of more than six percent (6%) except for short stretches where the topography makes it impractical to keep within such grade. In no case shall the grade exceed eight percent (8%), except where evidence satisfactory to the approving body shows that a lower grade is not possible.

On hillside streets, the grade shall be kept as low as possible, bearing in mind the advantageous development of the property, but no hillside street shall have a grade of more than ten percent (10%), except where evidence satisfactory to the approving body shows that it is impractical to keep within such grade. In no case shall the grade exceed fifteen percent (15%). Streets having grades between ten percent (10%) and fifteen percent (15%) shall in no case exceed one thousand feet (1,000') in length. [Formerly numbered Section 27-108; renumbered by Ord. No. 3058, eff. 2/21/87; 2197.]

11-1-1009: RIGHT OF WAY, ROADWAY, PARKWAY AND MEDIAN WIDTHS:

Each street shall have right of way, roadway, parkway and median widths conforming to the following (numbers indicate width in feet):

Rt.-of-Way Roadway Parkway Media Min.

Type of Street Min. Std. Min. Std. Min. St. Std. Local 56 60 36 - 10 12 -- Collector 60 64 40 - 10 12 -- Secondary Arterial 80 100 60 64 10 16 -- Major Arterial 4 Lanes 98 118 78 86 10 16 10 14 6 Lanes 122 142 102 110 10 16 10 14

Streets shall conform to the above standards (Std.) unless the approving body determines that the widths specified as standard are not practical. Where no standard width is specified but a minimum width is indicated, the approving body may require a width in excess of the minimum. Such widths shall not be reduced below the minimums (Min.) specified except that in hillside or mountainous areas the above

widths may be reduced below the minimums specified where evidence satisfactory to the approving body shows that such widths are impractical. [Formerly numbered Section 27-109; renumbered by Ord. No. 3058, eff. 2/21/87; 2197.]

11-1-1010: ALLEYS:

Alleys shall be provided where needed at the rear of all lots. Where two (2) alleys intersect, a cutoff of not less than ten feet (10') along each alley shall be provided. [Formerly numbered Section 27-110; renumbered by Ord. No. 3058, eff. 2/21/87; 2197.]

11-1-1011: WIDTH OF ALLEYS:

Alleys shall be at least twenty feet (20') wide. The approving body may require that an alley be at least thirty feet (30') wide at the rear of lots where the property is to be used for multiple residential, commercial or industrial use. [Formerly numbered Section 27-111; renumbered by Ord. No. 3058, eff. 2/21/87; 2197.]

11-1-1012: PEDESTRIAN WALKS:

A pedestrian right of way of a minimum width of ten feet (10') may be required through the middle of blocks which are excessively long and to provide convenient access to schools, parks, playgrounds, shopping centers, or adjacent streets. No such pedestrian way shall have a grade exceeding thirty percent (30%); provided that where stairways are made a part of the pedestrian way, the grade of the stairways shall not exceed seventy five percent (75%). [Formerly numbered Section 27-112; renumbered by Ord. No. 3058, eff. 2/21/87; 2197.]

11-1-1013: PRIVATE STREETS:

No private street shall be permitted in any subdivision, except where the approving body determines that a private street system will adequately serve the proposed subdivision, will not be a substantial detriment to the adjoining properties, will not disrupt or prevent the establishment of an orderly street pattern within the City, and will be constructed, improved and maintained in accordance with standard specifications for City streets. The design and improvement of any such private street shall be subject to all of the requirements prescribed by this chapter for public streets. In the event private streets are permitted in any subdivision, the area devoted to such purpose shall be excluded in applying the density standards of the zone in which the subdivision is located, and in determining the maximum number of residential units permitted in a condominium pursuant to the provisions of Section 11-1-1107C of this chapter. [Formerly numbered Section 27-113; renumbered by Ord. No. 3058, eff. 2/21/87; 2324, 2197.]
