PRIVATE STREETS
1. Private streets will be allowed in new developments where their use is
logically consistent with a desire for neighborhood identification and
control of access, and where special overall design concepts may be
involved. The use of private streets will be subject to review and
approval by the Planning Commission and the City Council.
2. Private streets will be permitted only where a satisfactory means of
providing for their maintenance and operation is demonstrated.
3. The use of private streets as a device for permitting inadequate design
will not be allowed.
4. The use of private streets is ordinarily limited to cul -de -sacs and to
minor local streets not carrying through traffic.
5. The design of all private streets shall be reviewed and approved by the
Public Works Department; and the construction shall be inspected by the
Public Works Department, with a standard inspection fee to be paid.
6. The following design standards shall be used:

permitted under Number 2 below.
2. Where special circumstances exist, deviations from the standards
will be subject to approval by the Public Works Department after
an individual review.
3. Streets shall be adequately designed to provide for lane delinea-
tion, street sweeping, and draingage control. Normally a standard
crown section with concrete curb and gutter on both sides will be
required, however other means of providing similar functional
characteristics may be considered.
4. Depressed approaches shall be used at all driveways where streets
have curb and gutter.
5. Concrete sidewalks shall be provided in the right of way, unless

2. Maximum - 15% for special circumstances
3. Minimum - 0.4%

least 20' of tangent adjacent to intersections. The tangent length
shall be increased where short radius curves are used near the inter-

2. Cul -de -sacs shall not ordinarily exceed 400' in length. Curb radius at
the turn - around shall be at least 40'.
3. Centerline radius shall be 150' minimum for loop streets over 800' in
