October Meeting Annoucement

DATE:    Thursday, October 19th
PLACE:  Hawthorne Lucky Lab Brew Pub, 915 SE Hawthorne Blvd
TIME:     11:30 a.m. Networking, 12:00 – 1:00 p.m.
TOPIC: Dairy Creek – Reconnecting to Restore Habitat Functionality
SPEAKER: Jason Magalen, Solmar Hydro, Inc.


Sturgeon Lake is located within the boundaries of Sauvie Island. Historically, circulation of the lake was maintained via, primarily, the Gilbert River (connected to the Multnomah Channel) to the north and Dairy Creek (connected to the Columbia River) to the south. Recent hydraulic changes have caused sediment infilling within Sturgeon Lake, decreasing water quality and degrading habitat. One of the selected methods to restoring lake function was to re-connect Dairy Creek between the Columbia River and Sturgeon Lake. This presentation will focus on the coordination requirements for the many stakeholders, and the ensuing 1D/2D hydraulic modeling, analysis, and engineering methods employed toward final design.

Mr. Magalen is a Coastal Engineer and Hydrographer with Solmar Hydro, Inc. in Portland, OR. He has 15 years of experience in hydrographic and marine geophysical surveying; and coastal, dredge, marine, and environmental engineering. The majority of his career has focused on hydrographic/geophysical and topographic surveying; hydrodynamic, sediment and water quality marine data collection, analysis and numerical modeling; coastal, estuarine, and riverine modeling; and evaluation and design of coastal structures. Type of projects have included contaminated and non-contaminated sediment erosion and transport assessments; wave and current studies; bridge scour evaluations; fish passage and wetland restoration projects; marine hydrokinetic (offshore wind and wave energy generation) studies; dredging project design; shoreline revetment and breakwater design; and construction management. He has worked for both the private engineering and consulting sector as well as the public (with the U.S. Army Corps of Engineers in Portland).

He holds a Bachelor of Science Degree in Civil Engineering from The Ohio State University, and a Master of Ocean Engineering Degree from Oregon State University. He is a registered professional engineer in CA, OR, WA, and Guam; is a NSPS/THSOA Certified Hydrographer; and is a certified Remote Pilot in Command (FAA Part 107). He is a past president of the Oregon Section of the American Society of Civil Engineers (OR ASCE) and is presently active with the NSPS/THSOA Exam Certification Board.

May Meeting Annoucement

DATE:    Wednesday, May 31st, 2017
PLACE:  Hawthorne Lucky Lab Brew Pub, 915 SE Hawthorne Blvd
TIME:     11:30 a.m. Networking, 12:00 – 1:00 p.m.
TOPIC: Drone LiDAR Data Acquisition
SPEAKER: Kevin Darrow, BD Aerial


More and more organizations are turning to unmanned aerial systems (UAS) solutions for water restoration projects. BD Aerial, a Portland-based drone services company specializing in LiDAR data acquisition, will dive into 2 examples of how organizations have used UAS to help solve environmental challenges.

Use-Case #1: What’s the best way to survey a working spillway without halting the operation and without putting personnel at risk?

Use-Case #2: In an effort to restore a fish habitat, (orga
nization) needed to remove water control structures, which would flood low-lying property. It was necessary to use a sensor capable of vegetation penetration to understand the topography of the project area and assemble the appropriate restoration plans.


Portland, Oregon drone services company, BD Aerial, was established in 2012 and is a leader in using UAS to safely inspect and document land and industrial assets. BD Aerial started in the Pacific Northwest and quickly became a preferred UAS service provider across the Nation; Now operating Worldwide with companies like Discovery Channel and National Geographic.

BD Aerial flies payloads including precision LiDAR systems, UV and Infrared sensors, and high-resolution cameras for photos, videos and photogrammetry. Using unmanned aircrafts, they capture actionable data for surveying high-risk landslide areas and terrain, maintenance inspections, engineering documentation, and construction mapping.


Kevin Darrow is Head of Business Development at BD Aerial. His role includes the company’s overall marketing strategy, project management, and strategic partnerships. In an industry that changes daily, he’s excited about exploring new UAS applications to help clients find creative solutions to their problems.

April Meeting Annoucement

DATE:    Wednesday, April 26th, 2017
PLACE:  Hawthorne Lucky Lab Brew Pub, 915 SE Hawthorne Blvd
TIME:     11:30 a.m. Networking, 12:00 – 1:00 p.m.
TOPIC: Western Oregon LID Guidance Template
SPEAKER: Maria Cahill, Green Girl Land Development Solutions


The Oregon Environmental Council, in cooperation with technical assistance from Green Girl Land Development Solutions LLC, developed a Low Impact Development guidance template that cities and counties throughout Western Oregon are using to create their own customized stormwater management manual. This template, titled “Low Impact Development in Western Oregon: A Practical Guide for Watershed Health” takes a watershed health approach to water quality, emphasizing practices that not only treat water, but also prevent it from leaving the site to reduce hydromodification and flooding.

For those jurisdictions currently adapting the template, it provides the detail needed to ease the successful implementation of LID to meet stormwater permit regulations and TMDL requirements. Designed for cities throughout Western Oregon, it eliminates problems caused when cities simply refer to the City of Portland manual, which may be inappropriate for their climate, geology, and stakeholde
rs and too complex for their needs.
Within the guidance, there are tools and resources that practitioners in the public and private sector, whether they have a stormwater management manual or not, might find useful including:

  • – A watershed health focused stormwater hierarchy;
  • – A decision matrix to quickly identify the best “best practices” for their site conditions and stakeholders;
  • – Simple and quick hydrologic models for sizing infiltration facilities; and
  • – The annual water balance model that helps users account for the runoff reduction volumes of practices such as vegetated roofs, compost amended soils, and tree planting.

Maria has collaborated on interdisciplinary teams to implement low impact development and green infrastructure in engineering and landscape architecture offices and her own firm for almost 20 years. In 2015, Maria wrote the LID Guidance Template for Western Oregon, which the Department of Environmental Quality (DEQ) funded, endorsed, and posted for download. Since starting Green Girl in 2008, Maria has trained jurisdictional staff throughout Oregon and provided technical resources and tools to help them meet their state water quality regulations (e.g., TMDLs, MS4). She recently completed a 6-week position at NOAA NMFS to provide technical assistance on the new SLOPES for HUD and the future SLOPES for Stormwater, Transportation, and Utilities, due in 2017. She currently works part-time in a limited duration position as a Stormwater Permit Writer for the DEQ while continuing to manage contracts with Green Girl. Maria has also taught numerous highly rated classes at colleges and to development industry professionals.
