What We've Been Doing from Lab 2 to Lab 3

This week, I really wanted the group to do research on specific GSI's to use in our project. We had an idea of what to use from the Project Proposal, but we weren't sure what we would be able to implement. We decided to use Stormwater Greenstreets, Right-of-Way Bioswales, Rain Gardens, and Stormwater Bump-Outs. Each team member was assigned a specific GSI to research and write a blog post about. Currently, we added my page about Right-of-Way Bioswales, along with Ina's fabulous Stormwater Bump-Out post to the background material section of our blog. Carolina also created an amazing rendering of what our project would look like, now the featured post on the blog. By Monday, Alex and Carolina will have completed their background material posts, and we will be able to move towards creating our GSI's through sketch-up. I was also able to create a helpful links page for those who want to do some more research, or want some more information about green stormwater infrastructures under the title: Links for Thought.

Below are some photos of our progress!

What will it look like?

Where does all the water go?

As evidence of the problem we will be addressing during this term, here are a couple examples of the flooding occurring there that we would use green infrastructure to help prevent.

Stormwater Bump-Outs

What are they: “A stormwater bumpout is a vegetated curb extension that protrudes into the street either mid-block or at an intersection, creating a new curb some distance from the existing curb. A bumpout is composed of a layer of stone that is topped with soil and plants. An inlet or curb-cut directs runoff into the bumpout structure where it can be stored, infiltrated, and taken up by the plants (evapotranspiration). Excess runoff is permitted to leave the system and flow to an existing inlet. The vegetation of the bumpout will be short enough to allow for open sight lines of traffic. Aside from managing stormwater, bumpouts also help with traffic-calming, and when located at crosswalks, they provide a pedestrian safety benefit by reducing the street crossing distance.” Advantages/Benefits: -shorten crossing distances on streets (safer for pedestrians) -gives perception of road narrowing so drivers slow down in this area -reduce stormwater overflow -add curb a...
