About EP&D
Our story
David Edmondson discovered his passion for planning and systems design after moving to Washington, DC in 2008. The DC of 2008 was undergoing rapid change, and the challenges of gentrification, traffic, and an underfunded Metro system were coming to the forefront of local discourse. Every-curious about how these forces might be shaping his home of Marin County, California, David began to research and write about urban affairs in that affluent suburb. In the process, he earned a readership of local planners, elected officials, and national advocates seeking to change how people understood their cities.
Not satisfied with simply writing from the sidelines, in 2017 David earned his master’s degree in City and Regional Planning from Cornell University. At first taking jobs on a case-by-case basis, David opened Edmondson Planning & Design in 2019 to consolidate and formalize his practice. His attention to detail, eye for design, and ability to balance the technicalities of planning with the real political environment on the ground makes the work of Edmondson Planning & Design stand apart.

HOVR Systems

To properly plan transportation capacity, HOVR Systems needed a model of typical use and peak use of their service. David developed a statistical model using a Poisson distribution to determine average daily usage and how crowded a new development might be on the worst day of the year.
Philippines Department of Transportation
Bus Planning Guide
As part of a federal decentralization initiative. the Philippines Department of Transportation (DOTr) decided to empower local towns to plan their own transit systems - something that always been done by national officials. To help equip towns in how to use their new powers, David drafted a bus transit planning guide for the Department and sketched a crash-course training for planners, politicians, and stakeholders to understand how to plan their transit systems.
