Shawnee County, Kansas selects Pushpin for parcel change detection

Press Release · February 5, 2020 · Minneapolis

Pushpin announced today that it had completed a parcel change detection project with Shawnee County, Kansas. The county competitively selected Pushpin for the project via a request for proposal (RFP). Under the contract, the county leveraged Pushpin's machine learning platform for identifying property changes. Pushpin compared 75,143 parcels in aerial imagery from 2014 and 2018 and identified 7,769 changed parcels (10%). Pushpin estimated an annual property tax increase of $2,413,980 associated with these changes.

"The appraiser's office selected Pushpin for our parcel change detection project because Pushpin's accuracy is excellent and their service is much faster and cheaper than the competition," said Steve Bauman, County Appraiser, Shawnee County. "Pushpin helped us identify numerous property changes such as additions and new construction that were not in our permit database. Their specific identification of the changes enabled our staff to focus on the higher priority changes such as new construction and garages first."

"It has been a pleasure working with Shawnee County and helping them accelerate their property assessment workflow," said Randy Milbert, President, Pushpin. "Shawnee County was the first in the state to leverage our machine learning platform in a county-wide project. We look forward to helping them in future years."
