W01: Site flow
Presented by Mark Buehrer and Robin McKennon Thaler
The conventional built environment often alters the natural hydrology of a site, resulting in sheet flow, erosion, streambed scouring, and flooding. A suite of design and construction techniques exist to return a site to conditions that mimic predevelopment hydrological profiles. This class will discuss the hydrology of undeveloped sites and discuss techniques that assist a project in approximating those conditions. Case studies of advanced approaches, covering the design and engineering aspects of integrated water management, will help illustrate concepts presented.

Presenters
Mark Buehrer - Founder/Director, 2020 Engineering
Mark is a registered professional civil engineer, author, and inventor with broad experience in engineering design, master planning, construction and project management.
Mark conceived and developed the concept of Wholistic Engineering, which provides an integrated "problem solving" approach that considers all issues and possible conditions related to the development of a project, such as: laws & regulations, social concerns, politics, special interests, economic & environmental issues, technology, and resources.
Mark's civil engineering work includes tasks such as Low Impact Development (LID) site design and stormwater management including natural rain garden systems and porous pavements, ecologically based waste-water treatment & water reuse systems, rainwater harvesting, and material recycling and composting, which are designed to help meet sustainable design goals. Mark has over 25 years of civil engineering experience.
Robin McKennon Thaler - PE, Mayfly Engineering + Design

Robin specializes in the design and planning of projects that are sensitive to both their social and natural environments. A LEED accredited professional engineer with over a decade of experience in civil engineering design and development, Robin’s unique natural resource background brings an important focus on low-impact design to all of the projects she contributes to.
In addition to providing the lead design and management of all projects that pass through Mayfly’s doors, Robin is known for her creative design approach and solid technical base and is asked to participate in a variety of value engineering studies and design charrettes for both public agencies and private clients.
