Planning for Successful Street Trees in Arid Climates

Planting trees and other large plant material in built-up urban areas in arid climates is always a challenge. More often than not, the constraints are numerous and the opportunities are few.  When a project is initially conceived, consideration must be given to all constraints, long before preliminary design plans begin. By developing a realistic plan... More

Historic Courthouse Square Redesign

Santa Rosa’s downtown square reunification integrates stormwater management and the planting of 86 new trees. The Santa Rosa Courthouse reunification is a long-awaited project to restore the city’s downtown square to its original layout, changing it from a space split in half by a four lane road to one continuous 1.5 acre site.

Which Trees Will We Lose First? Trees Most Vulnerable to Climate Change

Trees can do a lot of amazing things, but they can’t move away when the climate becomes inhospitable. Some can adapt to changing climate, and some can’t.  Which species will be hit the hardest? The most “vulnerable” species are those most susceptible to genetic degradation due to declining populations in the face of adverse environmental... More

Hit the Lights! Light Pollution’s Negative Impact on Urban Trees

Light pollution has become a frustration for many a star-gazer. Those who seek the heavens must drive far outside of urban centers and away from light-lined interstates in order to truly see the night sky, and even then, the effects of light pollution cannot be completely escaped. Light from our streetlights and buildings travels farther... More

A Walkable City is a Better City

Intrinsic to the success of cities and the quality of life they offer is how people move within them. For the past century, the car has been the central consideration in the design and planning of our urban areas. Increasingly, however, the car-dominated planning era is behind us, as city dwellers are more frequently walking,... More

Treating Hydrocarbons with Green Infrastructure

I’ve always believed in nature’s processes to manage compounds in the environment. Even as a young undergraduate engineer, I often wondered why we were removing natural systems like trees and soil rather than working with them, why we weren’t protecting and bolstering those systems in ways that enhanced their natural mitigating processes. The (relatively) recent... More

The Rise of the Pedestrian Plaza: Street-to-Plaza Conversions in the U.S.

In the U.S., cars are king. Our cities and neighborhoods are designed around how cars travel though them, and pedestrians are secondary – if a pedestrian can safely cross traffic, the area is deemed a success. It has long been said that if you plan cities for cars and traffic, you will get cars and... More
