This is a step-by-step how-to guide for creating a watershed management plan. This case study looks at how urban, rural, and riparian forests are critical to protecting water quality and reducing flooding in watersheds. Sustainable urban forest ecosystems provide benefits to not only the waters of a community, but also to the overall quality of life. Trees are a community’s green infrastructure, yet watershed councils are often unaware of how much of a role urban forests play in providing watershed benefits.
Restricted availability of public space in urban or ultra-urban environments poses a challenge to alternative stormwater management. Many low impact development (LID) best management practices (BMPs) that are available to slow down, store, treat, and infiltrate stormwater runoff require a footprint larger than what is available on a highly developed site or in an urban public right-of-way. While working to incorporate LID BMPs into the ultra-urban areas of our watershed, CRWA began looking at existing urban “green space” and sought ways to retain its aesthetic and public health amenities while also using it to treat stormwater runoff. In many of the dense neighborhoods of Boston, the only existing green space is street trees. CRWA investigated stormwater tree pits (a.k.a. tree box filters, tree boxes), a small scale bioretention BMP, which do not take up any more space than an ordinary street tree pit common to most urban environments. This document presents a general comparison of typical street trees and stormwater tree pits.
The Growing a Healthier Community Urban Forestry Analysis utilizes i-Tree Eco to present comparative tree data from four arid communities in southwest United States. The data compares each community’s study area, estimates tree coverage, the most common tree species and also estimates and compares the benefits trees provide each community. This report looks at the monetary benefits trees provide in five categories: greenhouse gas reduction, water benefits, energy benefits, air quality benefits and social benefits.
A website that features maps created from a wide range of datasets from equity, economy, education, environment, food and health issues. Within the environmental section of this site, national, state, or community level leaders are able to view mapped images for brownfield sites, solar and wind resources, air quality, and physical environment conditions related to health.
The Center for Watershed Protection reviewed a total of 159 publications to evaluate:
- the effectiveness of urban tree planting on reducing runoff, nutrient, and sediment pollution; and
- how effectiveness varies by species, over time, differences in planting sites, and different maintenance strategies.
This is an 8-year, comprehensive green infrastructure plan that identifies projects completed and planned so that the County reaches its stormwater management goals. Trees and other urban forestry solutions are incorporated into most of the projects.
