Rialto Municipal Code Ch. 17.44 Design Standards

The following shall be the standards of design except in those cases where the city planning commission determines that the size, or shape of the land, topographical conditions or proposed land use make compliance therewith impractical.

In reviewing tentative subdivision maps, the planning commission will require:

A. Dedications of land for streets, alleys, floodways and easements for:

1. Major streets and thoroughfares for opening or widening as shown on the general plan of the city, at the widths shown on such plan;

2. Local streets, not less than sixty feet in width or to complete dedications to that width of previously dedicated portions of streets, and located to provide natural drainage with no drainage pockets and adjusted to the topography, minimum number of intersections with major streets or thoroughfares;

3. Alleys, not less than twenty feet in width in all areas zoned or proposed for industrial, commercial, or multiple family use, with corner cut-off;

4. Easements:

a. For flood channels at such widths as the county flood control officer or city engineer may indicate,

b. Utilities at the rear, or side, of lots as may be necessary to serve the property and in a form satisfactory to the public utility companies which are authorized to serve the area;

5. Small parks or other public areas as may be appropriate;

6. Bridle trails and/or bikeways where, in the judgment of the planning commission, they may be necessary or desirable.

B. Dead-end streets shall be terminated by a turnaround area not less than seventy-six feet in diameter and shall be so arranged that all parts of any dead-end street are visible from the through street from which it runs.

C. Boundary line streets and half-streets will be permitted only when such partial dedications are necessary for the carrying out of the circulation element of the general plan or when assurances are presented, in writing, by the owner of the adjoining property of intention to dedicate the remaining parts of the street when such adjoining property is subdivided.

D. Curved streets in comparatively level locations shall have a radius of six hundred feet, or greater, and one hundred feet, or greater, in steep hillside locations.

E. Street corners shall have a minimum twenty-foot curb radius with the property line designed so as not to reduce the parkway widths.

F. All street connections shall be at approximate right angles.

G. Street grades, between six percent and ten percent, will be approved only for such distances as topographical conditions make a lesser grade impractical. A grade exceeding ten percent will be approved only when conclusive evidence shows a lesser grade is impractical.

H. Lots and blocks with dimensions suitable to the land uses proposed. Lot sizes in residential zones shall be not less than the number of square feet required by the zoning ordinance for the area in which the proposed lots are located and corner lots shall be five feet wider than the minimum required lot width.

I. Blocks shall ordinarily be two lot depths in width and not over one thousand three hundred feet in length. If shown at greater width, the planning commission may require easements or other assurances to permit later practical resubdivision.

J. Throughout the community the commission plans a general pattern of development, as shown on the map entitled "General Plan, City of Rialto," on file in the office of the city clerk, to which reference is hereby made for further particulars. The principles controlling the proposed layout of local streets in future subdivisions are:

1. Long blocks parallel with major thoroughfares to minimize the number of intersections with such thoroughfares;

2. To adjust streets to the topography and drainage requirements to consolidate in one right-of-way drainage and street structures;

3. To assure neighbors that subdivision of adjoining properties will not destroy the possibilities for future comparable subdivision of their own holdings.

(Ord. 684 § 26, 1975)

The provisions of this section shall apply to all development within the city, unless otherwise specified herein.

A. Landscaping and irrigation must be designated to conserve water through using the principles of water efficient landscape as defined in Chapters 12.20 and 12.50 of this code, except as exempted therein.

(Ord. 1133 § 2, 1991)
