Document Organization <br />Document Organization <br />This document is organized into five sections, plus references and appendices. Each section is briefly <br />discussed below. <br />Background <br />The background section provides a brief description of the landscape characteristics within the study <br />area. <br />Analytical Process and Elements <br />The analytical process and elements section overviews the procedures that were followed when <br />analyzing the subwatershed. It explains the processes of retrofit scoping, desktop analysis, field <br />investigation, modeling, cost/treatment analysis, project ranking, and project selection. Refer to <br />Appendix A for a detailed description of the modeling methods. <br />Project Ranking and Selection <br />The project ranking and selection section describes the methods and rationale for how projects were <br />ranked. Local resource management professionals will be responsible to select and pursue projects, <br />taking into consideration the many possible ways to prioritize projects. Several considerations in <br />addition to project cost-effectiveness for prioritizing installation are included. Project funding <br />opportunities may play a large role in project selection, design, and installation. <br />This section also ranks stormwater retrofit projects across all catchments to create a prioritized project <br />list. The list is sorted by the amount of pollutant removed by each project over 30 years. The final cost <br />per pound treatment value includes installation and maintenance costs over the estimated life of the <br />project. If a practice's effective life was expected to be less than 30 years, rehabilitation or reinstallation <br />costs were included in the cost estimate. There are many possible ways to prioritize projects, and the <br />list provided in this report is merely a starting point. <br />BMP Descriptions <br />For each type of project included in this report, there is a description of the rationale for including that <br />type of project, the modeling method employed, and the cost calculations used to estimate associated <br />installation and maintenance expenses. <br />Catchment Profiles <br />The drainage areas targeted for this analysis were consolidated into 16 catchments distributed between <br />two drainage networks and assigned unique identification numbers. For each catchment, the following <br />information is detailed: <br />Drainage Network <br />Catchments were grouped into drainage networks based on their drainage to a common <br />waterbody (i.e. Mississippi River or Rum River). The drainage networks were used to further <br />subdivide the report to aid with organization and clarity. <br />City of Ramsey Stormwater Retrofit Analysis <br />
