Sandy River Floodplain Handbook

As part of a larger flood hazard mitigation study for Clackamas County Emergency Management Department and the Sandy River Basin Council (SRBWC), Natural Systems Design was hired to develop a pilot floodplain restoration project in the Upper Sandy River watershed. A component of this project produced this handbook to educate the community about risks associated […]

Large Wood National Manual, Developing a National Manual for Planning, Designing, and Implementing Large Wood Projects

Design of engineered logjams (ELJs) and placement of large wood (LW) have become key to river restoration strategies nationwide. NSD team members, Leif Embertson, Mike Hrachovec and Tim Abbe were primary authors of this manual to train and educate restoration practitioners on the planning, design, placement and maintenance of large wood with an emphasis of […]

A Methodology for Delineating Planning Level Channel Migration Zones

by Patricia L Olson and Nicholas T. Legg; Tim B Abbe and Mary Ann Reinhart, and Judith K. Radloff

The Washington Department of Ecology developed a planning-level CMZ delineation (pCMZ) method to support local communities’ updates and implementation of the SMA requirements. This document describes the pCMZ approach in context of Washington State regulations.

The Great Salmon Compromise

by Ben Goldfarb from High Country News

In this editorial on The Columbia Basin Fish Accords, Ben Goldfarb acknowledges that funding for mitigation for the Columbia River dams has funded $1 billion worth of habitat restoration, but “can [restoration] replace free-flowing rivers?
