Overview of Revised Regional Methods Cont’d Employment (commercial and industrial) vacant land redevelopment land capacity method Urban reserve areas urbanization / capacity assumptions method Ex-urban city / county supply assumptions
Environmentally Constrained Land Identification (Title 3 & 13) (Mensher)
Exceptions Methodology (Kelley / Todd)
Exempt Tax Lots Identification Tax Exempt / Ownership Do all “Buildable Lands” hold capacity for future housing or jobs? • Yes / No • Why?
Although technically vacant and buildable, many lands are not likely to support new residential or commercial development over the next 20 to 30 years. EXAMPLES:
The majority of the following lands are removed from the buildable lands supply: • Private Streets; • Drainage detention facilities; • Shared lands under “common ownership”: Condominiums, HOA’s …etc. • Lands owned by: • Federal, State or Local Governments (some exceptions); • School Districts; • Park & Recreation Districts; • Churches and Fraternal Organizations; • Railroads, Transit Authority; • Golf Courses; • Utilities – (water, sewer, power, natural gas …etc.) • Exceptions:Urban Renewal Agencies, Housing Authorities, Port Authority, PDC
Vacant Land Calculations Allowed Density from ‘regional zone class table’ (Regional Zoning Crosswalk) No Constraints • Tax lot Area / Minimum lot size = Estimated Capacity in Units (rounded down to nearest whole unit) • EXAMPLE: 11,000 sq. ft. lot / 5,000 sq. ft. min. = 2.2 (rounded down) = 2.0 units capacity
Single Family Infill • Developed single family parcels that are larger than 2.5 times the minimum zoned lot size (2.2 in Portland) are considered available for infill development. • After making a deduction for the existing house, the rest of the developed parcel is treated the same as vacant land.
Vacant & Infill Land with Constraints • First, calculate capacity as if the whole lot was unconstrained. Next, calculate capacity with a density transfer on the unconstrained portion, assuming each unit could be built with 2,000 sq ft of unconstrained area (1,000 sq ft in Portland). • Take the minimum of these calculations to ensure the density transfer does not allow more units on the lot than would have been allowed if the whole lot had been unconstrained. • Some example calculations:
DU Capacity = tax lot area/ min. lot size (rounded down to nearest whole unit) Example:12,000 sq. ft. lot (w/1,200 sq. ft. buildable area) / 5,000 sq. ft. min. = 2.4 (rounded down) = 2.0 units capacity 12,000 sq. ft lot: 10,800 sq. ft. constrained 1,200 sq. ft. buildable area:
DU Capacity = unconstrained sq. ft. / 1,000 sq. ft. (rounded down to nearest whole unit) Example:12,000 sq. ft. lot w/1,200 sq. ft. buildable area /1,000 sq. ft. = 1.2 (rounded down) = 1.0 unit capacity 12,000 sq. ft lot: 10,800 sq. ft. constrained 1,200 sq. ft. buildable area:
MULTIFAMILY AND MIXED USE RESIDENTIAL CAPACITY METHODOLOGY (Armstrong /Conrad)
Vacant Land Capacity Calculations • Allowed Density from regional zone class table • No Constraints • Land Area * Allowed Density = Estimated Capacity in Units
Vacant Land with Constraints • Assumes Complete Transfer of Development Rights from constrained portion of lot • Low Density ( < 50 units/acre) • If Tax Lot < 5,000 sq. feet unconstrained lot area • 1 unit per 1,000 sq. feet unconstrained lot area • If > 5,000 sq. feet unconstrained lot area • Tax Lot * Allowed Density = Estimated Capacity in Units • High Density ( > 50 units/acre) • If Tax Lot < 10,000 sq. feet unconstrained lot area • 1 unit per 1,000 sq. feet unconstrained lot area • If > 10,000 sq. feet unconstrained lot area • Tax Lot * Allowed Density = Estimated Capacity in Units
MULTIFAMILY AND MIXED USE RESIDENTIAL REDVELOPMENT METHODOLOGY
Possible Redevelopment Sites • To be considered, the site must be either • SFR development in MFR or MUR zoning, or • Low density MF apartment (or condo) development in high density MFR or MUR zoning, or • Commercial (or light industrial) development in MUR zoning.
Redevelopment Thresholds • If currently built as MF • Then must add at least 50% more DUs • If currently built as SF, Com or Ind • Then must add at least 3 more DUs • Must exceed economic filter thresholds
Economic Thresholds • IF total assessed value / total lot area is less than threshold THEN eligible for redevelopment • Economic Threshold Values
Subsidized Redevelopment (Yee)
Employment (Commercial and Industrial) Vacant and Redevelopment Land Capacity Method (Todd)
Vacant Land • Apply the same kind of filters as residential, to exclude: • tax exempt • schools • utilities • etc. • Deduct 20% of environmentally constrained area as unbuildable • Capacity is measured in acres
Developed Land In addition to these filters and a 20% environmental deduction, developed lots are subjected to a set of economic criteria to determine eligibility for redevelopment:
Part Vacant Land • This approach does not account for large parcels that are only partially developed, with large vacant pieces being held for future development. • Developed tax lots that did not meet the redevelopment filter criteria were sent through an additional screen to identify the capacity on these parcels. • If a tax lot did not get through the redevelopment filter criteria, but has at least 1 acre of vacant land, the vacant portion is added to the supply.
Urban Reserve Areas Urbanization / Capacity Assumptions Method (Uba)
Process & Methodology • Agreement on urbanization criteria • Infrastructure (water, sewer, transportation) • Complete community possibility • Governance • Application of criteria and determination of urbanization timing • Urbanization timing for each UR, including split URs • Applying zoning to get capacity estimate for each UR
Buildable land outside the current UGB and Urban Reserve areas but still inside the three-county region; received information from two sources: • Unincorporated Ex-Urban Areas • Rural residential land • Measure 49 claims • Neighbor Cities • Information about future capacity received from local governments • Otherwise, capacity projections based on current conditions
