Stream Mechanics and Cost-Effective Management of Urban Stormwater
PROJECT DESCRIPTION
The City of Jefferson is split by two 8-digit hydrologic units, 10300102 (Missouri River Mainstem - Glasgow to Hermann) and 10290111 (Lower Osage River Basin). Within these river basins are two large cities, Jefferson City and Columbia, that are experiencing tremendous growth. The Missouri River runs directly through Jefferson City and is listed on the 303(d) list of impaired waters. Bear Creek and Hinkson Creek run through the City of Columbia and are tributaries of the Missouri River. Hinkson is on the 303(d) list.
OBJECTIVES
Provide training to 15-25 local and state government engineers representing up to 5 different city, county or state organizations on advanced stream mechanics and cost-effective management of urban stormwater problems. Topics covered will include natural channel management, aquatic stream ecology or biology, water quality indicators, stream bank stabilization, soil bioengineering, evaluation of soil loss due to in-stream processes and stages of stream evolution. The workshop will include evaluation of approved stormwater plans with class participants developing alternatives having less nonpoint source potential. Permitting and public acceptance issues will be specifically addressed.
METHODS EMPLOYED
This training will allow engineers to approach capital improvement projects with more awareness of alternatives to prevent nonpoint (NPS) source pollution and stimulate them to assess and modify practices that can contribute to NPS pollution. Specifically the course will provide a comparison between conventional stormwater management approaches such as hard armor, and practices based on stream mechanics such as energy management, protection of riparian vegetation and reduction of in-stream channel stress. The comparison will include the potential for NPS pollution as well as the functional and financial performance of the two approaches. Products of the workshop will include a course workbook with detailed technical references, checklists for plan review to help reviewers recognize common practices that cause NPS pollution and design guidelines for in-stream erosion. The course workbook will be customized specifically to meet the needs of the government engineers.
PRODUCTS
Two day training on stream mechanics and cost-effective management of urban stormwater; pre- and post-training questionnaire which will address the utility and relevance of the technical content and the engineer's ability to apply the material presented; three copies of the course workbook; a summary of a follow up to participants several months after the training recording additional feedback and how the training has been applied specifically in their jobs.
