Full Breakdown
Chapter 19.28 establishes the Downtown Specific Plan (DSP) district on the city's official precise zoning plan. Section 19.28.030 incorporates the DSP document by reference and states it "includes architectural and downtown design guidelines, site development standards and planned public parks and other facilities which will be implemented through zoning and subdivision regulations, development standards, design guidelines, public and private improvements and an economic development strategy." Section 19.28.040(b) resolves conflicts by giving the DSP document priority: "In the event of any inconsistency between this code and the DSP, the DSP shall control." The district is divided into numbered "blocks" under Section 19.28.050, each carrying its own development table.
For example, Table 19.28.090(a) sets Block 18 (Commercial Core) at minimum 0-foot front setbacks along Mathilda, McKinley, Taaffe, Sunnyvale and Iowa Avenues, 0-foot interior side and rear setbacks, a minimum useable open space of 50 square feet per unit, and states maximum height and lot coverage are governed "As provided in the DSP document" or evaluated "Per SDP" (special development permit) case by case. Section 19.28.090 also lets covered porches, stoops and stairways extend up to six feet into a required front yard, and ties additional height or density potential to state/local density bonus programs or DSP Section 5.1.3 community benefits. New construction or exterior changes to single-family homes in the DSP additionally trigger design review under Chapter 19.80.
Violations & Fines
Constructing, altering or occupying a building in the DSP district without meeting the applicable block's setback, lot coverage and open space table, or without complying with the DSP document's design guidelines where the code and DSP conflict, is a zoning violation enforced by the community development department; qualifying uses also require the specific permit (MPP, UP or SDP) listed in Table 19.28.070 or 19.28.080 before work begins.
