City of Portland - Water Bureau
The City of Portland Water Bureau contracted ES&A to provide technical support for Joint Permit Applications (JPA) for two off-channel restoration projects along the Sandy River in Oregon. One of the projects is in Dabney State Park, and the other is on the east side of Oxbow Regional Park. The proposed projects plan to restore off-channel aquatic habitat within the Sandy River main stem floodplain. Wetland determination data was collected and mapped within the proposed channel alignments and at any jurisdictional water or wetland resource locations. Temporary access corridors and the proposed fill disposal sites (identified by Portland Water Bureau) were also inspected to determine the presence or absence of wetlands. Portland Water Bureau used existing conditions mapping to improve the proposed off-channel alignment design, and ES&A provided technical support in preparing the JPA narrative and exhibits.
