In the realm of environmental conservation and land development, the TR 55 Worksheet 2, officially known as the Runoff Curve Number and Runoff form, plays a pivotal role. Originating from the U.S. Department of Agriculture’s Natural Resources Conservation Service, this document, last updated on April 4th, provides a structured approach for professionals to assess and record runoff data for specified projects. It is designed to capture crucial information concerning soil type, cover description, and the associated runoff curve number (CN) which is essential in evaluating the potential impact of precipitation on the land in question. The worksheet prompts the user to detail the project location, design, and review credentials, encouraging thorough documentation. It distinguishes between current and developed states of land, allowing for a comprehensive analysis of how development influences water runoff. Through calculating the CN across different areas and conditions, users can estimate water runoff volume following a precipitation event by applying specific rainfall data and formulas provided in the appendixes. This form, by facilitating meticulous calculation and planning, not only aids in the management and preservation of natural resources but also in the mitigation of adverse effects on the environment due to land development activities.
