[ ECA Challenges Explained ]
Building a structure or landscape design project in an Environmentally Critical Area (ECA) can be a challenging process. To help our customers better understand what they can expect, we have provided a roadmap and explanation of the ECA development process for homeowners in Seattle and King County.
Disclaimer: Environmental Construction Inc. specializes in figuring out what can be built on a hillside, but we are not permit specialists. Our team focuses on design, drainage issues, landscaping, deck rebuilding, and other structures. We can assimilate and excellent team and oversee your entire project.
