Course Title: How to Design for Stormwater Management for Ground Mounted Solar Arrays

Delivery Method: Live

Course Description: This course examines the fundamentals of stormwater management, site design, and erosion and sedimentation issues.It covers site and soil design principles, including grading, compaction, and changes to natural properties of sites. This information is beneficial to design professionals involved in the installation of larger solar arrays, as they have slanted and smooth surfaces that produce a high quantity of run-off during rain storms and snow melts.

Learning Objectives:

Learning Objective 1:
Learners will be able to reference state-level standards for stormwater management, which can impact solar array and site design decisions.

Learning Objective 2:
Learners will be able to identify and describe the components of ground-mounted solar arrays and explain why they pose stormwater management challenges.

Learning Objective 3:
Learners will be able describe the environmental consequences of erosion and sedimentation and explain how site design strategies and stormwater management techniques can prevent erosion and sedimentation from occurring.

Learning Objective 4:
Learners will be able to identify site conditions that need to be evaluated and established in order to formulate a sound stormwater management strategy with solar arrays, including the amount of impervious cover, ground cover, infiltration rates, runoff volumes, and water quality.

LUs: 2.0                                                                                              LU Type: LU|HSWs.

Prerequisites: Basis understanding of stormwater management principles and awareness of environmental problems with erosion and sedimentation

Advance Preparation: None
