Brea Municipal Code Ch. 18.92 Design — Streets and Highways

Access to a division of land shall be by means of an improved public street or highway. Where access cannot be obtained from an improved public street or highway, the advisory agency may approve a tentative map where access is obtained from an off-site ingress and egress easement which shall have a minimum width of twenty-five (25) feet and shall be improved with a minimum curb-to-curb or paved width of twenty-five (25) feet.

All streets, as far as practicable, shall be required to be in alignment with existing adjacent streets or their proper projection, and in general conformity with the master plan for the city.

Where roads or streets are so constructed that cut or fill banks are not wholly within the street line, such cut and fill banks shall be constructed so that they do all of the following:

A. Permit the development of abutting lots as building sites;

B. Protect the road and the abutting property against slides and settlements, all in a manner satisfactory to the City Engineer.

No street or highway shall have a grade of less than one half of one percent (0.5%) nor more than ten percent (10%). If, in the opinion of the City Engineer, topographical conditions do not permit meeting the minimum grade requirements, he or she may require mitigation measures to accommodate such deviation from said standards.

A centerline radius of not less than one hundred (100) feet shall be required on all local street curves. Where reverse curves are employed, there shall be a tangent of not less than one hundred (100) feet between the terminus of the first radius and the beginning of the next.

Street intersections shall be at as nearly a right angle as is possible, and care shall be taken in layout of intersections that adequate area is offered for dedication. Grades on local streets at their point of intersections with traffic streets or highways should be reduced to provide for the safe meshing of traffic, turning movements and standing of vehicles as they await opportunities to enter the traffic street.

The street arrangement shall be such that, in the judgment of the advisory agency, no undue hardships will be worked on the owners of adjoining property when they subdivide their land.

A.

1. The right-of-way required for arterial highways within or adjacent to the subdivision shall conform to the following dimensions:

a. Major, one hundred twenty (120) feet;

b. Primary, one hundred (100) feet;

c. Secondary, eighty (80) feet.

2. These widths shall be as measured on a line perpendicular to the centerline of the street in a horizontal plane.

B. The right-of-way width for local streets within or adjacent to the subdivision shall be based on the adjacent land use of the area to be served. Unless otherwise approved by the advisory agency the following widths shall be provided:

1. Industrial/commercial, sixty-four (64) feet;

2. Residential/commercial, sixty (60) feet.

C. Minor residential streets serving residential areas only may have a right-of-way width of fifty-six (56) feet with forty (40) feet of paved area, if approved by both the City Engineer and the advisory agency.

A. The width of all streets dedicated in conformity with this title shall be determined by the standards set forth in this chapter. The basis for all street, highway and road design shall be the lane. The width of the lane shall be related to the use to which the street or roadway will be put, and to the use of abutting land.

B. No street lane shall have a width less than the following:

1. Traffic lane. The width of a traffic lane shall not be less than twelve (12) feet.

2. Curb lane. The lane width of a curb lane (lane adjacent to a curb including median island) shall not be less than thirteen (13) feet.

3. Access lane. The width of an access lane shall be not less than ten (10) feet.

4. Parking lane. Parking lanes shall be a minimum of eight (8) feet in width.

C. When parking is permitted on traffic streets where time limits for parking are established, and where such parking may be prohibited during peak traffic hours, the parking lane shall be thirteen (13) feet in width so that it may function as a curb lane when so required.

The type of pavement for curbs, gutters, sidewalks and streets shall be determined by the City Engineer.

A. Cross-sections and lane configuration on city streets shall be in accordance with the circulation element of the general plan.

B. Freeways, limited-access ways and unlimited access state highways shall have a variable cross-section conforming to the standards of the state. Where the same are involved in any subdivision they shall be subject to all standards of requirements of the city. Standards of the state are deemed to be minimum standards that will be accepted.

A. Cul-de-sacs shall not be more than five hundred (500) feet in length when serving land zoned for industrial or commercial use or six hundred (600) feet in length when serving land zoned for residential use.

B. A cul-de-sac street shall have a turnaround at its terminus with a minimum forty-four (44) foot radius for the right-of-way and a minimum thirty-eight (38) foot radius for the paved area. Alleys should have a minimum twenty-five (25) foot corner radius and a minimum width of twenty (20) feet.

If the circulation element of the general plan shows a highway so located that any portion thereof lies within a division of land, that portion of the highway which is within the division shall be included in the design of the division unless the advisory agency determines that there is a reasonable probability that the general plan will be amended to remove or relocate the highway so that it is no longer within the division of land.

A. If the centerline has been established for a highway, the alignment of the highway shall conform to the established centerline. If no centerline has been established, the alignment shall be substantially as shown on the circulation element of the General Plan. The centerline curve radius of a major highway shall be not less than one thousand five hundred (1,500) feet. The centerline curve radius of a secondary highway shall be not less than six hundred (600) feet.

B. On any street, no centerline curve radius of less than two hundred (200) feet shall be provided. A centerline having an arc length of less than one hundred (100) feet shall not be permitted unless the centerline radius is greater than three thousand (3,000) feet.

A. Where street right-of-way lines intersect, and if both streets are local residential, the subdivider shall dedicate sufficient area to allow said lines to be rounded with a curve having a minimum radius of fifteen (15) feet unless otherwise determined by the City Engineer.

B. Where one or both streets are arterial highways, or one of the streets serves a commercial or industrial development, the subdivider shall dedicate sufficient area to provide a corner cutoff. Size of the cutoff required will be determined by subtracting the width of the narrowest parkway adjacent thereto from the required curb radius. In no case shall the cutoff be less than fifteen (15) feet long on the shortest side.
