TRIECA 2020 WEBINAR SERIES
Down to Earth: Overcoming Obstacles Specifying and Approving Soils for Use Within LID
Thursday August 27, 2020
12:00 to 1:00 p.m.
What is amended soil? It is soil that has been engineered with selected components added to meet specific needs of low impact development (LID) facilities.
The soils in these systems are responsible for slowing, treating and filtering the water from harmful metals, and nutrients like phosphorus and nitrogen. However, current LID guidance provides specifications for amended soils that can be difficult to achieve.
This presentation will introduce current specifications, and examine how a qualified landscape professional mixes and tests amended soils. We will also address the current challenges involved in meeting the specification, and explain how you can overcome them.
This presentation will finish by exploring what parts of the specification and soil characteristics are most important for the function of the LID facility, and how to confidently accept and monitor installation of soils that may not always match specified values or parameters.
1. Learn what amended soils are and why they are important.
2. Understand how amended soils are specified, mixed and tested, and learn how to overcome the current challenges associated with creating amended soil to meet current specifications outlined in guidance documents.
3. Learn how to evaluate and monitor amended soils, including what parameters are most important and how to accept soils that may deviate from specifications.
