Course Title: Designing Low Impact Development Practices for Water Quality
Delivery Method: Live Online
Course Description: This six-hour course will demonstrate how to design Low Impact Development (LID) practices with the goal of preserving water quality. The course begins with a focus on site investigation and testing before providing and analyzing LID practices and strategies meant for various site conditions. The course will also focus on pollutant loading analysis; identifying sources of pollutants, calculating loads, and increasing removal rates.
Learning Objectives:
Learning Objective 1:
Learners will be able to adopt site investigation strategies necessary to develop Low Impact Development practices, including the use of deep test holes, infiltration testing and percolation testing, for determining soil properties and limitations.
Learning Objective 2:
Learners will be able to recognize environmental conditions that may affect Low Impact Development practices such as slopes and potentially restrictive soil conditions.
Learning Objective 3:
Learners will be able to utilize Low Impact Development practices for various site conditions, including bioretention systems, permeable pavement systems, infiltration trenches and dry swales.
Learning Objective 4:
Learners will be able to identify sources of pollution, calculate pollutant loads and removal rates, and use wet and dry systems to enhance removal rates.
LUs: 6.0 LU Type: LU|HSWs.
