Summary
In the unincorporated Gorst urban growth area, Kitsap County lets developers earn up to 100% more density, height, or impervious surface coverage above a zone's base standard by providing specific public benefits like native habitat corridors or shared access. The program excludes the commercial and industrial zones and never lets a project exceed the zone's absolute maximum.
1. The incentive measures in this chapter apply to all zones and land uses within the Gorst urban growth area with the exception of the commercial (C) and industrial (I) zones... 3. Table 17.400.080(C) describes the public benefit and the resulting development incentive earned. Using the incentives, an applicant can earn density, height, or impervious surface coverage above the base standard allowed in the zone. In no case shall the maximum density, height, or impervious surface coverage exceed the maximum allowed by the zone. More than one public benefit and corresponding incentive may be earned up to one hundred percent of the bonus.

Full Breakdown
080(B) creates a voluntary incentive system for the Gorst subarea, the area covered by the Gorst Subarea Plan adopted under Ordinance 534 (2016). The incentive measures apply to every zone and land use within the Gorst urban growth area except the commercial (C) and industrial (I) zones. 080(C) lists the qualifying public benefits and the resulting bonus: a landscape plan retaining at least 20% of significant trees outside buffers earns a 50% density bonus (plus 50% height and 50% impervious surface bonuses); multilayered native landscaping on 30% of the site earns the same 50% package; and a minimum 35-foot native habitat corridor connecting critical areas, protected by a native growth protection easement, earns a full 100% density bonus plus 50% height and impervious surface bonuses.
Separate access-improvement benefits, such as shared roads, shared driveways, shared parking within a 1,200-foot radius, or screened consolidated loading areas, earn bonuses ranging from 25% to 100%. An applicant may stack more than one public benefit, but the combined incentive is capped at one hundred percent of the bonus, and in no case may the resulting density, height, or impervious surface coverage exceed the maximum allowed by the underlying zone. 080(D) cross-references the minimum, base, and maximum density, height, and impervious surface figures by zone for confirmation, and the ordinance directs that the zone-specific language controls if it conflicts with the table.
Because this is a county ordinance, it governs only unincorporated Kitsap County land within the Gorst UGA; it has no effect inside Bremerton, Port Orchard, Poulsbo, or Bainbridge Island.
Violations & Fines
Building beyond a zone's base density, height, or impervious surface coverage without documenting one of the qualifying public benefits in Table 17.400.080(C) is noncompliant with KCC § 17.400.080 and Title 17's zoning permit standards. The county reviews the site plan and public benefit documentation as part of the underlying land use permit; a project that cannot substantiate the claimed benefit, or that tries to exceed the zone's absolute maximum density, height, or coverage even after stacking bonuses, will have the permit denied or the plan sent back for correction rather than approved as submitted.
