Supply and Demand: How to Assess Impact Fees Based on Demand, Not Supply

This presentation provides a behind-the-scenes look at how a municipality refined its method of determining a building’s actual impact to the municipal water distribution and sanitary sewer collection systems. The City of Franklin provides the tools for developers and their engineers to estimate their anticipated sanitary sewer demand based on various factors, depending on type of building use. In the past, the applicant would select the type of drainage facility being planned (residential ranging from one-bedroom apartments to mobile home parks to single family homes; and commercial uses including churches, country clubs, office buildings, gas stations, etc.) In order to more accurately and equitably assess and quantify the impact to the sanitary sewer collection and water distribution systems, the Franklin Water Management Department crafted a new method of anticipating demand. The goal was two-fold: to collect the appropriate impact fees equitably across the wide range of developments and to provide developers and engineers a better method to anticipate demand in an ever-changing and speculative market. The previous method of calculating impact fees was based on the requested meter size. This meant a 10,000 square foot building housing a couple of retail stores, for example, could potentially pay the same impact fees as a multi-story 100,000 square foot office building. The new method is more directly tied to actual square footage and the occupancy group (i.e. Assembly, Business, Mercantile, etc.) expected for the square footage. This presentation is planned for 30 minutes (20-25 minutes with reserved time for Q&A). BIO: Michelle Hatcher, PE, serves as Director with the City of Franklin Water Management Director.
