RESOLUTION NO. 2005-372
RESOLUTION OF THE CITY COUNCIL OF THE CITY OF
CHULA VISTA APPROVING CHANGES TO THE CHULA
VISTA CONSTRUCTION STANDARDS AND SUBDIVISION
MANUAL
WHEREAS, the Architectural and Transportation Barriers Compliance Board (Access
Board), is an independent federal agency devoted to accessibility issues for people with
disabilities. It is composed of representatives of disability groups, the design professions,
building code organizations and federal enforcement agencies. Under the Americans with
Disabilities Act (ADA), the Access Board is charged with recommending accessibility guidelines
to federal enforcement agencies for all issues governed by the ADA. Once the Access Board
recommendations are adopted by the Department of Justice (DOJ), the guidelines serve as the
basis for enforceable standards for public agencies subject to the ADA and the Architectural
Barriers Act (ABA); and
WHEREAS, in July of 2004, the Access Board published proposed accessibility
standards to update the standards adopted by the DOJ in 1994. The proposed guidelines represent
the cumulative efforts of the Access Board and a broad cross-section of interested parties. After
adoption, the standards were published for an extended period for public review and comment
before final publication by the Access Board; and
WHEREAS, before publishing the final guidelines, the Access Board reviewed over
2,500 comments received during the public comment period and incorporated many of these
recommendations into the guidelines. The proposed guidelines have now been accepted by the
DOJ and published as an Advanced Notice of Proposed Rule Making (ANPRM). They are now
undergoing an additional period of public review and comment; and
WHEREAS, the first Americans with Disabilities Act Accessibility Guidelines
(ADAAG) were adopted by the DOJ in 1994 and have served as guidance for the City in all of
its construction standards. The proposed changes to existing City standards regarding curb ramp
design are consistent with those guidelines and also incorporate some recommendations from the
Access Board's proposed ADA/ABA Accessibility Guidelines and draft Public Rights-of-Way
guidelines; and
WHEREAS, the Access Board's recommendations are not yet enforceable regulations
under the ADA. Nevertheless, staff recommends the City incorporate some of the proposed
changes now in anticipation of the various federal agencies (including DOT and DOJ) ultimately
approving the Access Board's recommendations.

be 1%.
(11) The maximum longitudinal street grade or cross slope at 90 degrees to a
cross gutter shall be 3% for 25 feet (8m) from any edge of the cross gutter.
This grade may be increased at residential intersections, subject to approval
of the City Engineer, if the intersection is designed as a maximum
comfortable acceleration sag vertical curve designed for a minimum speed of
25 mph (40kph) [Le., Length of vertical curve = 3.125 feet x Difference in

the intersection and for at least 50 feet~ (15m) past the nearest curb
lines of the intersecting street as long as all aoolicable ADA requirements fat'
