<br />B. <br /> <br />I <br /> <br />Examine Other River Issues <br /> <br />e <br /> <br />1) Identify Areas of High Flood Hazard <br />Identify locations on the Roaring Fork River, the Fryingpan River and at tributary <br />confluence points where flood hazards are substantial, defined as any flood which <br />threatens the usability of human residences or infrastructure or critical <br />environmental values or resources. Such identification will take into account <br />mapped SO-year, lOO-year and SOO-year floodplains, existing structures affecting <br />stream capacity, development within floodplain areas, and proposed changes to <br />existing or historic floodplains through human activity. These areas will be <br />identified on maps similar to those described under Task A.2), above, and will be <br />described in a fashion similar to that described in Task A.2), above. <br /> <br />2) Identify Habitat and Recreation Concerns <br />Present a general assessment of habitat value (riparian vegetation, fish, wildlife) <br />for the Roaring Fork and Fryingpan mainstems using existing data. Assess the <br />recreational value, in terms of recreation-days, for representative reaches of the <br />study and extrapolate overall recreational value from those assessments. Present <br />estimates of the economic value of recreational activities tied to river access, <br />stability and overall health. Identify threats to those recreational uses associated <br />with stream instability. Identify public access needs, opportunities and constraints <br />and alternatives. <br /> <br />3) Existinl!: Identify Infrastructure at Risk <br />Identify all public and private infrastructure items at risk from stream instability <br />or flooding. Such structures may include, but are not limited to, bridges, ditch <br />diversion structures, roads, railroads, water and wastewater treatment plants, <br />recreation facilities, public utilities, schools, medical facilities and agricultural <br />structures. Identify the nature and the cause of the flooding or instability risk and <br />recommend mitigation measures. Distinguish between "HIGH", "MEDIUM" and <br />"LOW" risk situations based on a matrix taking into account likely flood <br />frequency, structural integrity, replacement cost, and other relevant factors. <br /> <br />e <br /> <br />4) Clarify Regulatory Requirements <br />Develop a "cookbook" for local property owners and local government officials <br />compiling regulatory requirements and programs relevant to floodplain and <br />stream stabilization activities. This document should summarize federal, state and <br />local regulations relevant to floodplain activities, disturbance of riparian habitat, <br />earthmoving, water resource development, or other actions which might <br />contribute to stream instability or floodplain manipulation, noting which agencies <br />have jurisdiction under various circumstances and describing procedures for <br />complying with most common requirements. The cookbook should be written in <br />layman's terms so it can act as a user-friendly guide for regulators, elected <br />officials or landowners. <br /> <br />e <br />
