• Growing Population

– Projected 20,000 increase by 2037

• Housing Shortage

– Rental vacancy under 2% – Single-family housing supply

• Code Challenges

– Difficult to achieve densities envisioned in Comp Plan

Background

• 2016 Infill Task Force

– Multi-disciplinary Steering Committee – Series of Focus Group Meetings

• Final Report – November, 2016
• Priorities

– Developable Lands Mapping Tool – Infill Development Education – Land Aggregation Entity – Code Amendments

Infill Task Force

• Enable development that achieves Comp

Plan densities

– RSF 4 -10 Dwelling Units per Acre – Increased densities around Centers & Corridors

• Efficient use of developable lands

– Enable development of smaller, irregularly shaped, or challenging development sites

• Expanding ownership opportunities
• Compatibility with existing neighborhood

Code Amendment Goals

• Comprehensive Plan Land Use Policy

– Single-family residential areas

• 4 to 10 units per acre
• Provisions for alternative processes for

additional housing types

– Public realm

• Public or private area where people interact

– Efficient use of land in proximity to mixed-use centers and corridors

Adopted Policy

Adopted Policy

• Comprehensive Plan

Urban Design Policy

– Design new construction to support desirable behaviors and create a positive perception of Spokane

1st Phase Infill Code Amendments

• Compact Residential Lot Standards
• Pocket Residential Development
• Cottage Housing
• Alternative Residential Subdivisions

my.spokanecity.org/projects/infill-housing-strategies-infill-development/

• RSF-C Zone provides

compact lot standards

– Reduced front & rear yard setback – Minimum lot size of 3000

• sq. ft.
• Within ¼ mile of CC core

land use & transitional sites

• Requires a rezone

Compact Residential Standards

• Min. Rear

Setback 25 ft. 15 ft.

• Min. Lot Width:

40 ft. 36 ft. Example Lot

Existing RSF- C Eligible Distance – CC Core

RSF zone CC/DT zones

• Compact Lot Standards Established for RSF-C

zone (Table 17C.110-3 & SMC 17C.110.209)

• Apply standards to RSF within ¼ mile of CC

zoning without rezone

• Apply to transitional sites without a rezone
• Create a new category “Compact Lot

Standards” in Table 17C.110-3

• Revise the “applicability” of Compact lot

standards in 17C.110.209(B)

• Allow some flexibility consistent with

underlying zoning density

• Where can this tool be used?

– Sites less than 1.5 acres in most residential and commercial zones

Pocket Residential Development Allowed outright in Residential Single- family (RSF), or with a conditional use permit, rather than through a zoning change to RSF- Compact (RSF-C).

– Buffer/Transition – Integration into Code

Street Shared Private Access

CONCEPT ILLUSTRATION

Steering Committee Recommendation

• Pocket Residential Development -

SMC 17C.110.360 – Proposed amendment to allow in RSF zone (subdivision required) – Only parent site must have street frontage – Enhanced design standards to ensure compatibility with neighborhood – Companion amendment to driveway standards

Pocket Residential Development

Proposed Changes

Common Driveway Unit Fronting

• nto a Street

Unit Fronting

• nto a Private

Street, Drive, or Walkway

• Alternative Residential

Subdivisions - SMC

17G.080.065 – Rename “unit lot subdivisions” – Applies to 9 or fewer lots – Align with pocket residential standards – Applies to pocket residential, cottage housing, and similar – Supported by updated driveway standards

Unit Lot Subdivisions

Steering Committee Recommendation Cottage Housing should allow for a portion

• f units with a higher maximum size and the

ability to attach units and mix housing types.

– Location – Buffer/Transition – Past Work and Integration

Cottage Housing SMC 17C.110.350 What’s not changing:

– Type II conditional use – Overall amount of required open space

Cottage

Key changes:

– Allow subdivision – New housing types

• Attached unit homes (up to 2

units)

• Carriage units (located above

a garage structure)

– Increase floor area to 1,200 sq. ft. – Increase rear setback to 15 feet – Enhanced design standards to improve compatibility

• Requirements (R)

– Must be satisfied by any plan prior to building permit approval. – An applicant may seek a deviation from certain requirements through the design departure process.

• Presumptions (P)

– Presumptions are guidelines that are meant to be applied, but with some flexibility. – Can be overcome if applicant proposes an alternative that achieves the intent of the presumption.

• Considerations (C)

– Features and concepts that an applicant should consider in preparing a plan. – May assist in overcoming certain presumptions and in gaining acceptance for a plan.
