In this episode, we dive deep into the process of stream restoration, highlighting the innovative techniques used to manage water flow and restore natural habitats. Throughout the project, we employed a variety of features such as rock veins, log veins, wood toes, soil lifts, and floodplain grading to control water movement and enhance the overall ecosystem.
One key element is the use of imbricated cross veins, designed to slow the water at a controlled rate, creating a stable grade behind the creek. These vein arms play a vital role during flood events, allowing the water to dissipate slowly into the pool, ensuring the stream remains stable and safe. Additionally, log veins effectively redirect water flow, preventing erosion and stabilizing the banks.
We also implement wood toes with soil lifts to stabilize steep slopes. In areas where excavation isn't feasible, these soil lifts provide the necessary support by creating vertical gains in the land, which are then planted for environmental restoration. The process reduces costs compared to traditional rock stabilization methods and allows for natural plant growth.
In managing floodplain capacity, we strategically move the stream and use the old channel to create wetlands. This helps retain groundwater, creating a balanced ecosystem while also meeting environmental obligations for wetland preservation. Across the entire project, thousands of these structures are being installed, each contributing to a larger goal of stream restoration and ecological sustainability.
