System Development Charges are referred to as "SDCs" and are a way for cities to collect money from developers to offset the costs that are added to the city for serving the new building, whether for a new home or a new business. SDCs are calculated through a methodology that is based on a particular system's Master Plan's Capital Improvement Plan. Meaning each of the City's critical systems: water, sewer, stormwater, transportation (streets), and parks each have a plan that details the needs to serve 20 years of growth, each plan contains a Capital Improvement List that provides the costs for each item that is needed to grow the system. Engineers calculate the costs of these items and then base those costs on units. Each system has a different measurement of units that are then equitably charged to developers based on the demand that they will place on the particular system. Following is a link to the State Law: ORS 223.302, which gives detailed information on how SDCs are established, collected for, and how they may be used.
