§ 16.08

A.

Grades for local streets may not exceed sixteen (16) percent unless approved by both the transportation and fire departments. In areas with an elevation of five thousand (5,000) feet or more, street grades shall not exceed ten (10) percent, except that grades up to fifteen (15) percent may be approved for distances not to exceed two hundred (200) feet.

B.

Street grades of less than 0.50 percent may be approved only when engineering design shows that local drainage provisions are adequate and steeper gradients cannot be obtained. The utilization of combinations of steep and minimum grade lines as a means of generating embankment materials for on-

site tract grading to the detriment of street maintenance and good engineering design will not be approved. Every effort shall be made to design street grades which will be in conformance with the existing terrain.

(Ord. 460.137 § 3.4, 1997)

Curves of streets with right-of-way width of sixty (60) feet or less shall have a minimum centerline radius of three hundred (300) feet in comparatively level locations and shall have a minimum centerline radius of one hundred fifty (150) feet in comparatively steep hillside locations.

1.

A minimum curb return radius of twenty-five (25) feet shall be provided at intersecting streets designated as collector or local streets.

2.

(Ord. 460.137 § 3.6, 1997)

16.08.070 - Alleys.

A.

Improved alleys not less than twenty (20) feet in width may be approved at the rear of all lots intended for industrial, commercial, and multiple-family uses.

B.

Alley intersections shall have minimum corner cutbacks of twenty-five (25) feet or shall provide unobstructed sight distance as approved by the director of transportation.

C.

Dead-end alleys shall provide an adequate turnaround.

D.

Part-width alleys shall not be permitted.

(Ord. 460.137 § 3.7, 1997)

16.08.080 - Lots.

A.

Lot size shall not be less than the minimum required by the zoning classifications applicable to the subject property, and shall be consistent with the comprehensive general plan for Riverside County.

B.

Corner lots shall be designed to provide a building site equal to that required for interior lots in the same zone.

C.

When lots eighteen thousand (18,000) square feet or less are proposed, the depth of lots shall not exceed two and one-half times the width. When lots greater than eighteen thousand (18,000) square feet are proposed, the depth shall not exceed four times the width.

D.

When lots are crossed by major public utility easements, each lot shall have a net usable area of not less than three thousand six hundred (3,600) square feet, exclusive of the utility easement.

E.

When a lot includes an access strip, the access strip shall not be less than thirty (30) feet in width. In no case shall the length of the access strip exceed six hundred sixty (660) feet. When the access portion abuts a dead-end street or cul-de-sac, the combined length of the street and the access strip shall be no more than one thousand three hundred twenty (1,320) feet in length in a nonhazardous fire area and six hundred sixty (660) feet in a hazardous fire area.

F.

Side lot lines shall be at approximately right angles or radial to the street centerline, except where terrain or other restrictions make such design impractical.

G.

Lots less than two acres in gross area shall not have double street frontage except that in hillside areas where the topography requires, lots may abut two or more streets provided that the frontage and vehicular access is from only one such street.

H.

No lot shall be divided by a city, county, school district or other taxing agency boundary line.

I.

The minimum lot frontage on a knuckle or cul-de-sac street shall be thirty-five (35) feet measured along the property line unless otherwise specified in the development standards of the zoning classification.

J.

Lot frontage along curvilinear streets may be measured at the building setback line in accordance with development standards of the zoning classifications.

K.

Garage door setbacks for all residential zones shall be twenty-four (24) feet for a conventional door or twenty (20) feet for a roll up door, measured from the back of the sidewalk to the face of garage door or the face of the curb if no sidewalk is required, or twenty (20) feet from the street right-of-way, whichever setback is greater.

(Ord. 460.137 § 3.8, 1997)

A.

Any contiguous property that is owned by the land divider shall be included within the boundaries of a land division when necessary or desirable in the design or improvement of the land division if the remaining parcels are less than forty (40) acres in size,

B.

Any contiguous property that is owned by the land divider, but not included within the boundaries of the land division, shall be of such size and shape as to conform to the provisions of this title, the land use ordinance, the comprehensive general plan of Riverside County, or any applicable specific plan; otherwise it shall be included within the boundaries of the land division.

(Ord. 460.137 § 3.9, 1997)

A.

No land division map shall be recorded unless public access is provided from each parcel of the land division to a city, county, county service area, community service district, state or federal road that is maintained for public use. Public access to a road maintained by a property owner's association may be allowed if the board determines that there is no other feasible means of guaranteeing maintenance of the road for public use, and if the association has the unqualified right to maintain the road pursuant to recorded conditions, covenants and restrictions which require the association to maintain the road and such requirement cannot be amended or terminated without the consent of the county.

B.

The requirement for public access may be waived under the following circumstances.

1.

If a parcel map creates four or less parcels and public access over intervening lands cannot be offered for dedications, an appurtenant private easement for ingress, egress, roadway, and public utility purposes may be approved, provided:

a.

The land to be divided is not zoned for commercial, industrial, or multiple- residential use;

b.

No parcel under one acre in size is created unless only two additional parcels are being created;

c.

If no improvements are required, the private easement is not less than twenty (20) feet in width, and is duly recorded, is perpetual in duration, and is not subject to liens and encumbrances which might impair or defeat its purpose. If improvements are required, a minimum of forty (40) feet is required;

d.

The access easement owned by the land divider is not an exclusive easement or specifically written to prohibit further division of the land.

2.

If a subdivision map has been previously recorded that permitted private streets without the requirement of offering the streets for dedications, a private road easement may be approved, provided the easement grants the new lots unrestricted access rights to the existing private streets.

C.

Public access is not required if each parcel created is forty (40) acres or more or is a quarter of a quarter section.

(Ord. 460.137 § 3.10, 1997)

16.08.110 - Design of subdivision to provide for future passive or natural heating or cooling opportunities.

In order to provide for future passive or natural heating and/or cooling opportunities in a subdivision, the following considerations shall be taken into account: subdivision lot design, size, configuration of structure, orientation in an east-west direction, local climate, contour, configuration of the parcel to be divided, and other design and improvement requirements. Such provision shall not result in reducing allowable densities or the percentage of lot which may be occupied by a building or structure under applicable planning and zoning in force at the time the tentative map is filed.

These requirements do not apply to condominium projects which consist of the subdivision of airspace in an existing building when no new structures are added.

(Ord. 460.137 § 3.11, 1997)
