The minimum building setbacks are as follows:

  • A. Along Lone Hill Avenue and Gladstone Street, minimum of twenty-five feet for structures up to twenty feet and forty feet for structures higher than twenty feet. Height limitations set forth in this section do not include minor architectural projections;

The following areas shall be fully landscaped and irrigated, maintained in good appearance and kept in a weed and disease free manner:

  • A. Streets. All setback areas along Gladstone Street and Lone Hill Avenue shall be landscaped and maintained adjacent to public rights-of-way. Parking areas should be screened as much as

possible utilizing berms, shrubs, and other decorative treatments of sufficient size and height to meet this requirement.

  • B. Overall Site. All building sites shall have a minimum landscaped coverage equivalent to ten percent of the total lot area. Such landscaping shall be evenly distributed over the site and consist of an effective combination of trees, ground cover and shrubbery. All areas not utilized for structures, parking or other permitted uses shall be landscaped.

  • C. All interior side and rear yards and setbacks shall be fully landscaped. (Ord. 1150 § 1, 2005)

§ 18.540.240. Signage.

The provisions of Chapter 18.152 of this title shall apply. No signs shall be installed until a master sign program for the project has been approved by the review authority pursuant to Chapter 18.12 of this title.

(Ord. 1150 § 1, 2005; Ord. 1324, 6/10/2025)

§ 18.540.250. Architecture.

  • A. Due to the highly visible location of this site, a common architectural theme is encouraged to provide a high quality product. Structures shall be designed utilizing a western or Early California architecture design and shall be approved by the review authority pursuant to Chapter 18.12 of this title.

  • B. Buildings shall be expected to employ treatments, such as the staggering of planes along exterior walls to create pockets of light and shadow, to break up the mass and provide relief from monotonous, uninterrupted expanses of wall. Other features, such as the use of curved corners and varying roof lines should also be considered as means to dramatically change the appearance and add vitality. Also, in order to improve the appearance of a project from adjacent rights-of-way, the rear elevation of those structures facing the right-of-way should receive special architectural enhancement as well.

  • C. Sensitive alteration of colors and materials should be used to produce diversity and enhance architectural effects. While no category of exterior materials is considered "correct," the use of a particular material should, as a rule, exemplify the special characteristics of the product or be demonstrative of its unique application. Paint, in general, should be considered an enhancement tool but not be considered a replacement for the use of textured surfaces.

  • D. Detailed architectural guidelines shall be prepared for final review and approval by the planning commission prior to the granting of precise plan approvals for any development within Area I-B.

  • (Ord. 1150 § 1, 2005; Ord. 1324, 6/10/2025)

  • A. Internal circulation shall be designed so as to provide safe and efficient access to all properties within Area I of the specific plan.

  • B. An intent of Specific Plan No. 24 is to provide a comprehensive development program which encompasses all of the properties that comprise the project area. To fulfill this objective, prior to the approval of any project within Area I-B, a finding shall be made that the project takes into consideration and makes all necessary provisions to accommodate safe and efficient access to all other properties within the area as required to fulfill the intent of the specific plan.

  • C. Internal circulation shall include adequate provision for pedestrian circulation by including walkways, landscaping, benches or seating, trellises or similar amenities.
