Infill Design Toolkit – A Guide to Integrating Infill Development into Portland’s Neighborhoods


This is a good example of:

Influencing quality design for infill residential projects through design prototypes & patterns

Narrative:

The Infill Design Project’s objective is to improve the design of multi-dwelling and rowhouse development in neighborhoods outside Portland’s Central City. The city sought to both use infill as a tool and limit impacts by:

  • Accommodating greater density while respecting desired neighborhood character;
  • Encouraging quality design while facilitating affordable housing;
  • Providing for automobile parking while contributing to pedestrian-friendly street frontages;
  • Meeting our density goals while providing usable open space;
  • Minimizing impervious surfaces while ensuring durable vehicle areas; and
  • Allowing the new while respecting the old.
A modern duplex included as one example of higher density housing.

Design Principles for Residential Infill Development (Based on design guidance from the Comprehensive Plan, Community Design Guidelines, Zoning Code, and other City documents):

  1. Contribute to a Pedestrian-Oriented Environment
  2. Respect Context and Enhance Community Character
  3. Consider Security and Privacy
  4. Provide Usable Open Space
  5. Design for Sustainability

Design Strategies – Best practices for context-responsive infill design

  1. Medium-Density Residential Development
  2. Respond to Basic Neighborhood Patterns
  3. Parking
  4. Minimize Scale Contrasts
  5. Design for Privacy
  6. Create Usable Outdoor Spaces
  7. Alternative Housing Types

Design Prototypes

Portland developed housing prototypes (illustrations of possible residential design) in order to communicate residential infill goals.  The city developed five different prototypes to reflect a range of neighborhood settings and housing needs.

Prototypes needed to follow building regulations, be financially realistic, minimize auto presence in public view while providing at least one space per unit, respond to the context of the neighborhood, and include models conducive to ownership.

References – Medium Density Infill Housing

The Infill Guide includes extensive examples of medium density housing in Portland (including detailed building statistics and details such as gross/net density, lot size, year built, etc).  There are also photo references of historic buildings and examples from around the country.

  1. As usual, Portland does excellent planning work. On the issue of design compatibility of infill, I have found very good guidance. However, it is not clear if the City can do more than encourage compatible design. I have seen infill that represents the usual “McMansion” buildings one might expect to see in Hillsboro.

    Can you clarify what the City or what individual neighborhoods can do to assure compatible development?
