20D.230.20 Transition Overlay Areas.

20D.230.20-010 Applicability.

(1)    Transition Overlay regulations shall apply to those portions of “complying zones” within the Transition Overlay area, as designated in Table 20D.230.20-010(5), Protected and Complying Zones.

(2)    Transition Overlay development standards shall apply in addition to the development standards applicable in the underlying zone. Where there is a conflict between the standards, the most restrictive shall apply.

(3)    Property in complying zones rezoned to a protected zone on or after April 14, 2007, shall not be designated “protected,” as defined in this chapter, nor shall property in zones that would otherwise be designated “complying” as a result of that rezone be designated as such. Instead, the developer of the property rezoned to a complying zone shall have the responsibility of providing within the property’s own boundaries protections that would otherwise be accorded to “protected” zones in this chapter. Those protections would buffer uses in protected zones from, and mitigate the impacts associated with, uses typical of complying zones, which may include, but are not limited to, various manufacturing, assembly, warehouse, entertainment, and other uses that operate both at day and at night, at noise levels consistent with existing regulations governing complying zones. The mitigation may be achieved through visual and audio screening, increased setbacks, building placement, open space, landscaping, architectural screening, berms, fences, topographical separation, or other methods that meet the intent of this provision as determined by the Code Administrator.

(4)    Both within and outside Transition Overlays, decision makers authorized by the Community Development Guide to decide discretionary approvals may condition discretionary approvals and development permits, including but not limited to site plan approvals, to minimize adverse impacts on other properties and uses and to carry out the policies of the Comprehensive Plan.

♦ A 300-foot-wide Transition Overlay shall apply.

Ο A 150-foot-wide Transition Overlay shall apply.

1 ORS (Outside Redmond Single-Family) refers to primarily single-family residential zones in neighboring jurisdictions that have an allowed density of eight or fewer housing units per gross acre.

2 ORM (Outside Redmond Multi-Family) refers to primarily small lot single-family residential zones and primarily multi-family residential zones in neighboring jurisdictions that have an allowed density greater than eight units per gross acre.

(6)    Except as otherwise provided in this division, the Transition Overlay shall be located within the complying zone.

(7)    The Transition Overlay shall be measured at right angles along the boundary of the complying zone, except as described in subsection (8) of this section.

(8)    The Transition Overlay shall include the following areas within the protected zone:

(a)    Street and railroad rights-of-way;

(b)    The Sammamish River, parks or easements for park and open space uses owned by a public agency, and trail rights-of-way or corridors where a public agency owns or leases the right-of-way or corridor or has an easement or equitable servitude for the right-of-way or corridor.

(c)    Native growth protection easements and easements or equitable servitudes with similar purposes.

(d)    Undeveloped critical areas and their buffers where structure construction is generally prohibited through Chapter 20D.140 RCDG, Critical Areas, provided that the Technical Committee determines that the area is unlikely to ever be developed. (Ord. 2390; Ord. 2332; Ord. 2302; Ord. 2027)
