cOU IL AGENOA REPORT
' FROM: Randy Rossi, Interim Community Development Director; By: Gary
Price, Associate Planner.
SUBJECT: Parking and Driveway Standards Amendment
CAO RECOMMENDATION:
Introduce ordinance to print approving a negative declaration on environmental impact
and amending the Parking and Driveway Standards as recommended.
BACKGROUND:
The proposed revisions are intended to modernize, update and clarify the city's parking
and driveway standards. The standards were originally adopted by ordinance in 1981.
Staff is asking council to consider and adopt, with or without changes, the new standards
by ordinance. Attached is Exhibit "A", showing the draft standards showing the proposed
changes and portions of the document to be deleted.
SIGNIFICANT IMPACTS:
The Community Development Director approved a negative declaration of environmental
impact for the proposed amendment (refer to the attached environmental review). The
proposal is not expected to result in any significant environmental impacts.
CONSEQUENCES OF NOT TAKING AN ACTION:
The current parking and driveway standards would remain in effect and would continue
to be applied in the design and compliance review of new projects.
DISCUSSION:
1. The Average Parking Space:
The most substantive change to the standards is the establishment of the "average space",
replacing the larger size standard parking space. It responds to the down-sizing, by
manufacturers, of the standard sized vehicles. It is also intended to yield an overall
increase in parking spaces in a given development and avoid cramped parking by using
compact spaces in an attempt to meet a project's parking requirement. The new stall
is an average size between the present compact and full-sized parking stall. The use of
compact spaces, under the new standards, would be limited only for exceptional
circumstances, such as saving a tree or using otherwise unusable space on the site for
parking.
2. Miscellaneous Changes:
Other changes include clarifying the text and adding sub-headings to make the document
more reader friendly, updating driveway geometries to meet current fire codes, requiring

COUNCIL AGENDA REPORT

parking lot .landscaping to be designed and installed in accordance with the city's
landscape standards for water conservation, adding new provisions for motorcycle spaces
and bicycle spaces and including provisions for truck access in commercial and industrial
parking lots. Staff feels these changes are necessary to upgrade the regulations and
provide more clearly described details.
3. Administering the Standards:
Since the Community Development Department processes and reviews parking plans and
issues parking lot permits, the Director or the Department would replace the City
Engineer as the lead authority in administering the new standards. The City Engineer
would still review and authorize technical requirements such as driveway -design_and.
encroachment into the public right of way.
4. Possible Future Revisions:
The Planning and Architectural Review Commissions have suggestedthat a. higher
minimum percent of landscaping in parking lots may be desirable. The present standard;
is 5 percent. Because of the present water shortage and sensitivity to the issue,.,<staff.
feels that such changes to landscape standards should not be made at this time. Metre"
study on this matter is needed with review by the commissions. _
PREVIOUS REVIEW
During a study session, the Planning Commission, on October 18, 19899 reviewed-the
proposed "average cars" parking space standard and unanimously approved the.iiandard
(Commissioners Hoffman and Roalman were absent). The commission felt an`applicant
should be able to request approval of a few smaller "compact car' spaces-within-.a
parking lot of "average car" spaces, if justified by unusual circumstances such as `saving
a tree or using otherwise unusable space (refer to the attached minutes).
OTHER DEPARTMENT COMMENTS
Community Development Department and Public Works Department staff worked
together to produce the revised standards. Fire Department staff reviewed the pertinent
changes to the standards and supports the revisions.
ALTERNATIVES
The Council may:
1. Adopt the attached ordinance approving the revised parking and driveway
standards as proposed.
I
2. Adopt the attached ordinance with changes made to the proposed revised parking
and driveway standards as deemed appropriate.

SPECIAL MEETING

PRESENT: Commissioners Charles Crotser, Barry Karlskint, Janet

Parkins and Driveway Standards
The commission discussed the proposed "average cars" parking
space standard. On motion of Commr. Schmidt, seconded by Commr.
Crotser, commissioners voted five to none to recommend to the
council that the prosposed standard be adopted, with the
understanding that an applicant could request approval of a few
smaller "compact car" spaces within a. parking lot of "average
car" spaces, if justified by unusual circumstances such as saving
A tree or using otherwise unusable space.
Land Use Element Update
The residential-policies committee will provide its edited
version to commissioners Friday October 20. The commission
revised its tentative meeting schedule.
Commisioners and staff discussed commercial policies. Areas of
concern included quantified estimates of current space and future
needs for various types of commercial development, location of
neighborhood stores, and subcategories with the "services and
manufacturing" designation.
The meeting adjourned to the regular meeting scheduled for
October 25, 1989, at 7: 00 p.m. in the Council Chamber of City
Hall.
