Underutilized Lands Inventory Nick Finio NCSG 2 -14 -20 nfinio@umd. edu

Overview ● ● ● National Center for Smart Growth project team: ○ Nick Finio ○ Margaret Curran ○ Hyunjoo Eom Project timeline ○ Ongoing - June 2020 Project geography ○ Montgomery and Prince George’s Counties ○ Focus on Purple Line Corridor ■ Targeting east Silver Spring, Long Branch, Langley Park, Riverdale Park, New Carrollton

Purpose ● ● ● Identify and map, at the parcel level, developable land of the following types: ○ Publicly owned land ○ Tax-exempt land ■ Focus on non-profit and religious land ○ Vacant land (of any ownership type) ○ Underutilized or underdeveloped residential or commercial land Products: ○ Maps of developable land ○ Lists of developable parcels of land End state: ○ A suitable jumping off point for further refinement: ■ Financial feasibility of certain projects ■ Development suitability for certain project types (eg single family, multifamily, mixed use)

Data and sources ● ● Tax parcel data from both counties ○ With various characteristics: ■ Zoning ■ Ownership category (e. g. federal, state, municipal, county, private) ■ Lot size, vacancy information, assessed value, etc Various GIS layers from the state or counties: ○ Purple Line alignment ○ Opportunity Zones ○ Qualified Census Tracts ○ Floodplains ○ Slopes

Primary selection criteria for all land parcels Unsuitable Suitable Inside 100 -year flood plain Outside 100 -year flood plain Protected public land (parks, schools) Other public land Slope > 20% Slope < 20% Parcel size < 0. 2 acres Parcel size > 0. 2 acres All other land (private ownership) Excluded from analysis Included for further analysis

Secondary selection criteria - suitability analysis - - Transportation Distance from Purple line Lot Size and Shape Suitable size Suitable shape Ownership Improvement value/land value Public or private Tax exempt Land Use and Zoning Vacancy Current Zoning Other characteristics - Qualified census tract, opportunity zone, All of this data will be included as a list of data in each parcel. To be determined: how to weight these variables in a “suitability map”

Weighted overlay analysis 1. Build Model a. Classify data b. Establish Weights c. Overlay data 1. Produce Suitability Map 1. Select Suitable Parcels Example Model and Output

Preliminary data analysis - examples Final data product = list of Suitable Parcels, with these attributes 1) Land ownership (owner information, tax exempt status) 2) Current land use (vacant, commercial, industrial, public, etc) 3) Parcel characteristics a) Land value, improvement value b) Parcel size c) Year structure built d) Distance to Purple Line e) Qualified census tract, opportunity zone 4) Current zoning 5) Weighted suitability “score”

Example of Map Overlays - Prince George’s
