Stacy Benjamin, Principal Ecologist, has conducted hundreds of wetland and natural resource projects since 1996. Project experience ranges from due diligence site investigations to full-service permitting and agency compliance on sites ranging from less than an acre to thousands of acres and for projects ranging from residential and commercial development to infrastructure and utility projects. Representative project experience follows below, additional project experience is available upon request.
Wetland and environmental permitting services for over a dozen Clean Water Services stormwater and sanitary sewer projects. Services have included conducting wetland and waters delineations, assessing vegetated corridor (wetland and stream buffer) impacts to meet Clean Water Services sensitive areas certification process, preparing vegetated corridor mitigation plans, and obtaining wetland removal/fill permits from the Oregon Department of State Lands and Clean Water Act Section 404 permits from the U.S. Army Corps of Engineers.
This City of St. Helens project involves replacing 2,000 linear feet of existing storm sewer pipe and an undersized outfall to the Columbia River. Wetland services provided in support of this project included a wetland and waters delineation and obtaining permits from the Oregon Department of State Lands and the U.S. Army Corps of Engineers for impacts to jurisdictional waters, including a Clean Water Act Section 10 permit for impacts to a navigable water. A land use permit was also obtained from the City of St. Helens to comply with their sensitive lands ordinance and the protective measures for significant wetlands, riparian corridors, and protection zones required under their municipal code.
This project included permitting for new correctional facilities for the Department of Corrections and a new state hospital for the Department of Human Services. Services included groundwater monitoring, wetland delineation, rare plant survey, evaluation of the ditches on the site to provide habitat for federally listed fish, preparation of the wetland permit application and a mitigation plan involving 70 acres of wetland mitigation. The project involved extensive coordination with the design teams for both projects to ensure a collaborative approach to site development planning and permitting. U.S. Army Corps of Engineers and Oregon Department of State Lands permits were obtained to fill approximately 95 acres of wetland, one of the largest permitted wetland fills in the history of the Oregon State Removal-Fill program.
Services provided for this project included a wetland and waters delineation and jurisdictional determination on the approximately 5,600 acre site. Drainage features were identified as ephemeral, intermittent, or perennial based on the presence or absence of a bed and banks and indicators of hydrology. Drainage features were evaluated for the presence or absence of a downstream connection to a Traditional Navigable Water, and Corps jurisdictional determination forms were prepared. A Joint Aquatic Resources Permit Application was prepared for the U.S. Army Corps of Engineers Seattle District, and the project was successfully permitted.
A wetland and waters delineation was conducted on approximately 300 acres of public lands administered by the Oregon Bureau of Land Management (BLM) Vale District Office. An Environmental Assessment was prepared to meet BLM’s responsibility and authority to manage these public lands in accordance with the BLM Baker Resource Management Plan. The Environmental Assessment evaluated direct and indirect environmental consequences for three project alternatives and for each of the five phases of the project. Design features were developed to minimize the potential of the project to impact Columbia spotted frog, a candidate for federal listing under the Endangered Species Act and a BLM special status species known to inhabit the project site. A Finding of No Significant Impact and Decision Record were published by the BLM, and the NEPA process was completed without appeal.
