ES&A, LLC PROJECT EXPERIENCE

Seaside SD K-12

Wetland Delineation

ES&A is in the process of conducting a wetland delineation on a study area located in Seaside, Oregon for the Seaside School District. The wetland delineation will provide technical documentation of wetlands and other jurisdictional water resources to assist in completing the proposed urban growth boundary (UGB) expansion and future impact analysis for proposed K-12 facilities.


Portland Bureau of Environmental Services 

Wetland Delineation Report & Functional Assessment

ES&A was on team contracted with the City of Portland Bureau of Environmental Services (BES) to conduct a wetland delineation for a channel restoration project within the Oaks Bottom Wildlife Refuge in Oaks Bottom Park, within Multnomah County, Oregon. The channel restoration project will enhance the general quality of habitat by restoring a historic channel that connects the Willamette River to the main open water portion of the refuge. 

Wetland Delineation Report & Stream Restoration Plan Technical Support

ES&A was on team contracted with the City of Portland BES to conduct a wetland delineation and site investigation the Johnson Creek Oxbow project area in Multnomah County, Oregon. The site is a part of a project to restore a segment of channel recently eroded and scoured from high seasonal flows. ES&A delineated all wetland resources on-site, including floodplain forested wetlands and the Johnson Creek Ordinary High Water Line (OHWL). 

Wetland Delineation Report & Functional Assessment

ES&A was subcontracted by the City of Portland BES to conduct a wetland delineation and site investigation on a study area associated with Johnson Creek in Multnomah County, Oregon. The site is a part of a restoration project aimed at enhancing the floodplain of Johnson Creek by designing and constructing flood storage and flood attenuation. ES&A delineated all wetland resources on-site, completed a baseline functional assessment on wetlands and creek channel and submitted their findings to the Oregon Department of State Lands (ODSL).


Clean Water Services Vegetation Monitoring

Plant & Shade Monitoring

ES&A conducted annual vegetation monitoring for Clean Water Services (CWS) from 2009 through 2018. Tasks included recording cover data for all plant species, stem counts for native woody species, measuring canopy cover, and photo monitoring.  Data was used to assess plant growth and morality, invasive species cover, natural recruitment, woody plant density, plant species diversity, effectiveness of/need for herbivory protection, and other limiting factors.


THPRD Somerset West Park MP

ES&A completed field data collection, impact analysis, on-site wetland delineation and permit documentation for proposed Master Plan improvements of this existing park in Beaverton, Oregon. They assisted the design team in the assessment of invasive species removal, daylighting an existing piped creek and integrating restoration planting and naturalized planting with free play areas within the park setting. 


Portland Water Bureau – Sandy River Enhancement

Tech Memo, Impact Assessment & Permit Support

ES&A was contracted by The City of Portland Water Bureau to provide technical support for Joint Permit Applications (JPA) for two off-channel restoration projects along the Sandy River in Oregon. 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 the locations of any jurisdictional water or wetland resource. Existing conditions mapping was used by Portland Water Bureau to improve proposed off-channel alignment design and ES&A provided technical support in the preparation of the JPA narrative and exhibits.


Cannon Beach Park Master Plan

Natural Resource Assessment

ES&A completed a Natural Resource Site Assessment within existing City park properties in the north end of Cannon Beach, Oregon.  The assessment area included the Les Shirley Park, NeCus’ Park, Ecola Creek Park and Whale Park Kid’s Beach and all of these are located along the lower reach of Ecola Creek.  The site assessment includes a preliminary inventory of natural resources within and adjacent to the existing park properties and the existing conditions information was incorporated into the parks and trails master plan prepared for the City of Cannon Beach.  The assessment also determined potential areas where proposed park improvements may result in unavoidable natural resource impacts and provided a jurisdictional review summary of permitting requirements by state and federal agencies.


Metro Cooper Mountain 

Plant Monitoring Surveys

Working with Metro Regional Government, ES&A staff assisted in an established long-term botanical monitoring program at Cooper Mountain, which will allow Metro to evaluate vegetation management practices in upland prairie habitats.  In 2006 and 2017 ES&A conducted nested frequency counts within established macroplots to assess different land management practices.


Port of Portland SIDC-TRIP Weir Improvements, Fairview, Oregon

ES&A preformed as a subcontractor for an environmental assessment of a mitigation project surrounding a flow control structure in Fairview Oregon. The overall project aims to replace the existing flow control structure on Port of Portland Land. A wetland delineation report as well as a Joint Permit Application (JPA) was completed and turned into the Oregon Department of State Lands (DSL) and U.S Army Corps of Engineers (USACE).
