Comprehensive zoning data for the region was one of MetroFuture’s “Most Wanted Datasets.” I subsequently managed the production of a regional zoning map incorporating information from 101 individual cities and towns. Components of the atlas include digital district boundaries for both base zoning and overlay districts and a corresponding table with allowed uses, estimated permissible densities, and the permitting process for multifamily housing. I led the effort to define a data schema and data collection process, oversaw the data collection, and co-authored the introductory report. My team also developed a back-end data infrastructure and interactive mapping application that allows users to search, filter, and comment on the information in the atlas. 

I led the effort to create a comprehensive public dataset of vehicle ownership and utilization in Massachusetts. The Vehicle Census uses data from the Registry of Motor Vehicles transaction and safety inspection programs. I directed the effort to clean and process these records to produce an anonymized vehicle-level dataset with garage location, estimated daily VMT, and estimated GHG emissions for most vehicles in the state. The Census also includes summary statistics for municipalities, census tracts, and 250m grid cells statewide, making it easy to map and visualize neighborhood statistics. The data are useful for tracking electric vehicle adoption, estimating VMT, and setting parking standards. Municipalities use the data for GHG baseline inventories and net zero performance measurement. In 2022, the Massachusetts Legislature adopted a law requiring MassDOT to create a vehicle census on an annual basis. That resource is now available to the public at https://geodot-massdot.hub.arcgis.com/pages/vehicle-census. 

Comprehensive digital parcel data for the region was one of MetroFuture’s “Most Wanted Datasets.” I designed and managed the initial efforts to combine standardized parcel and assessor records from 350 Massachusetts municipalities into a single feature class with additional attributes drawn from remote sensing, administrative records, and MAPC imputation. 

I led an 11-year effort effort to create a collaborative digital inventory of residential and commercial development projects across Massachusetts. First launched in 2012 as a replacement for handwritten comments from town officials, MassBuilds is now a multifunctional web application with user accounts, distributed data entry, moderation of user contributions, search functionality, and data downloads. Each iteration of the application has been informed by outreach to identify priority features and needs. The database now contains information on over 5,000 development projects across the state, and is a principal mechanism for municipal input for MAPC’s land use projections. Massbuilds encompasses almost three quarters of all net housing growth from 2010 to 2020, making it a useful resource for researchers and local stakeholders.

I oversaw an initiative to collect online rental listings and transform them into an ongoing resource for monitoring the region’s housing market. Funded by contributions from six municipalities, our team maintained a web application to scrape information from multiple online rental housing websites, deduplicate and geocode the listings, extract and generalize content using natural language processing, and distill into quarterly reports and comprehensive cleaned data downloads.
