 | BLI Model Development Capacity | The first step of the Bureau of Planning Sustainability's Buildable Lands Inventory (BLI) model is used to identify parcels that are likely to redevelop in the City of Portland -- parcels that are either vacant or significantly underutilizing their allowed development capacity. FAR and building height limits are the primary limiting factor on development in employment, commercial, and high-density residential areas. In multi-family and single-family residential areas, capacities are determined by the allowed number of residential units. This portion of the BLI modeling process consists of 3 basic steps:1) calculate existing building square footages and allowed development limits (in terms of building square footage or number of residential units); 2) identify parcels using significantly less than their allowed development capacity (using less than 20% of available capacity, not including any development bonuses or incentives);3) apply development constraints to these parcels and calculate remaining capacity in terms of building square footage, allowed number of residential units, and allowed number of jobs. The attached graphics illustrate the process in more detail. This featureclass is the result of that analysis. It is used to determine the total supply of residential and employment land, which is an input into subsequent steps of the BLI model, which allocates forecasted units and jobs to different areas of the City. | Development | 05/20/22 07:31 AM |

 | Historic Resource Inventory | The Historic Resource Inventory (HRI) of approximately5,000 properties was completed in 1984 by the City of Portland as a project of the Historic Landmarks Commission.It is a planning and research tool that was intended to support development ofthe City's Comprehensive Plan and comply with Statewide Planning Goals. Beinglisted in the HRI is not a historic "designation, although a demolitiondelay period may apply under City of Portland regulations. In 2013, the original HRI records were exportedfrom older files to MapWorks. Some data fields were abbreviated. There may beinconsistencies and errors in the data. For example, many sites have beenredeveloped since 1984, and demolitions were not recorded. Also, over 100 buildings have been removed from the HRI onrequest of property owners. The HRI records cannot be updatedto reflect all thechanges and removals that have occurredsince 1984. The data is therefore provided “as-is.” City of Portlandrecords can be checked to verify if properties have been redeveloped ordemolished. | Development | 06/25/24 05:31 PM |

 | Main Street Network | The Neighborhood Prosperity Initiative (NPI) and Main Street Network is a PDC program focused on community economic development at the neighborhood scale. A community-driven, self-help approach is at the heart of this work. With grants, training, and support from PDC, each district is responsible for planning and implementing projects to improve the local commercial district. | Development | 08/18/20 07:38 AM |
| | Neighborhood Contact Applications | The neighborhood contact process provides an opportunity for people who live, work or otherwise pass by a development site to learn about a project before the owner submits for permits or applies for a land use review.
