Wenatchee Valley Development Probability
This map was created for the Trust for Public Land as part of the Wenatchee Watershed Vision project. When buying a home or deciding to relocate to a new area, every homeowner has a different checklist of priorities. That said, there are some basic factors, such as water and electricity availability, slope, and proximity to the highway or other roads, that nearly every homeowner considers. This map predicts where such development would likely occur based on these and a number of other variables such as views, distance to rivers and streams, and urban amenities.

John Wayne Pioneer Trail
This map was created for the Trust for Public Land. The map was designed for a TPL-sponsored bike ride along the 22 mile length of this rails-to-trails route in the Cascade Mountains.

Sauk River Estimated Channel Movement Area
This map was created for the Washington Deparmtment of Natural Resources Riparian Open Space Land Owner Program. Working together with LeeSaa Consulting and TerraGIS, we delineated the probable zone of future avulsion events in the Sauk, Nooksack, and Cowlitz rivers and ranked the forested, privately owned parcels to assist DNR in identifying and contacting land owners that might be interested in enrolling in the program.

Measure 37 Claims in the Hood River Valley and Central Willamette Valley
These maps were created for the Sightline Institute. The Hood River and Central Willamette Valleys of Oregon have been ground zero for Measure 37 claims. In the Hood River map, properties with active Measure 37 housing claims are showing in red. Yellow is land that's zoned for agriculture. In the Central Willamette map, each dot represents 10 potential new residents resulting from the Measure 37 claims.

Storm-Related Trail Damage
This map was created for the Washington Trails Association and shows trails and roads that suffered storm damage in the North and Central Cascades and the Olympic Mountains.

Salmon Spawning Survey Maps
These maps were created for the City of Bellevue as a sub-consultant to The Watershed Company. The City of Bellevue conducts an annual salmon spawner survey in the City's salmon spawning streams, and there are often some fairly sizable fish observed, such as this Chinook carcass that was found in Kelsey Creek.

Impervious Surface in the City of Tukwila
This map utilizes impervious surface data from the USGS Seamless site to illustrate the relative level of development along the Duwamish River. Greener areas are less impervious, red areas are more impervious..

Cascade Land Conservancy Protected Lands
This map illustrates the recent conservation accomplishments of the largest land trust operating in the Puget Sound Region. (Original design by Matt Stevenson, this version modified by Christopher Walter; worked completed while at CommEn Space).
