Cost Estimates for Financial Assurances - Street Improvements (Effective January 2021)

The following unit costs will be used by City Engineering to determine the amount of Financial Assurance to be collected for Street Improvements. The subdivider may submit an engineer’s cost estimate or bid tabulation to be used in lieu of these unit costs subject to City Engineering approval. These costs were adjusted by approximately 3% from 2020. All figures were rounded to the nearest dollar for ease of calculating assurances.
