Property taxes are based on the valuation of the property, which are appraised by the county every other year. A property tax increase would only occur if the value of the property increases. The benefits would include an increased sale price, community improvements (sidewalk, street, and other infrastructure improvements), an improved and revitalized neighborhood, increased business traffic, etc. The benefits from this project in part depend on participation by the community and success stories resulting from the project. The CO Brownfields Tax credit can be up to $525,000 depending on the cost of the cleanup and landowners can sell their tax credits for cash.
