7550 MERIDIAN CIR N, SUITE 120 | MAPLE GROVE, MN 55369 PAGE 3 OF 8 DETERMINATION OF PROJECT BENEFIT Benefits derived from the proposed project generally take two primary forms: 1) added value to the property due to the elimination of encumbrances and/or the viability of different uses;1 and 2) the avoidance of future costs to maintain existing stormwater management features. The following sections describe and quantify benefits associated with both of those categories and identify the entities most closely aligned with receiving the benefits. Determination of future cost avoidance include both one-time costs (for example, a major drainage system repair) and long-term costs over a 100-year life cycle (as a comparison to the life cycle of the proposed project).2 DRAINAGE SYSTEM REPAIR AND LONG-TERM MAINTENANCE COST AVOIDANCE The RCD 4 open channel between County Road C and Terrace Drive is in a state of disrepair that cannot feasibly be corrected via annual minor maintenance. The draft RCWD Watershed Management Plan envisions a system-wide repair of the RCD 4 open channel, including this project location. This work will no longer be necessary in the project corridor if the proposed stormsewer piping project proceeds. Table 2 displays anticipated costs for repairing the RCD 4 open channel between County Road C and Terrace Drive, if the proposed project to replace the open channel with pipe is not completed. Per RCWD policy, the cost of major drainage system repair is allocated to the landowners who drain to the system. For RCD 4, these landowners constitute the RCD 4 Water Management District (RCD 4-WMD). Therefore, RCD 4-WMD benefits the most from avoiding major repairs. 1 Added value to properties are primarily estimated using land values available through parcel data published by Ramsey County. No appraisal work was completed to estimate these values. 2 All costs provided herein are in present-day (2020) dollars. No inflationary costs are included.
