Providing rural property owners with the necessary information to make informed decisions when developing, and managing their land. Serving the Pacific Northwest since 1987.

Greenbelt Consulting is an environmental assessment and consulting service designed to help property owners make informed decisions concerning their land. Landowners can minimize the degradation inherent in land clearing, road grading, and homesite construction by becoming more knowledgeable about the natural landscape of their property. Development and long-term maintenance costs can be reduced, and property value increased through coordinated planning and careful consideration of homesite, solar potential, septic systems, and access. Through assessment of your land's topography and existing natural elements, Greenbelt Consulting can suggest practical ways to maintain ecological integrity while blending comfort, safety, and utility.

The wooded and pastoral nature of the Pacific Northwest landscape is rapidly changing due to the influx of people. The very peace and beauty that has attracted people is in danger of disappearing as a result.

Greenbelt Consulting endeavors to Prevent Tomorrow's Problems Today.

A Brief History of the Salish Sea

How We Got to Where We Are 

 Presented by Elliott Menashe

Thursday, April 10 @ 6:30 p.m.

Clinton Community Hall

6411Central Ave, Clinton, WA 98236

free admission

                With a lot of help from researchers and scholars throughout the Pacific Northwest, forest ecologist Elliott Menashe will explore the history of the Salish Sea, Puget Sound, and Whidbey Island--offering a series of geologic, climatologic, ecologic, environmental, anthropologic/cultural, archeological, and geopolitical vignettes to help us understand our place in the restless and unruly landscape we call home.

To plan wisely for the future, we must understand the past. Menashe will take us on a tour from the end of the Pleistocene, through the most recent continental glacial advance and retreat--when first peoples hunted the Columbian mammoths that roamed what would become Whidbey Island, to the evolution of the great climax forests, discovery by European explorers, and up to the present day. 20,000 years in 90 minutes (with a 10 minute break). What a ride!

Learn some simple land-management practices that each of us can adopt here in the present--- to help preserve for the future our part of this vast, unique, and remarkable region.

 The lecture is being organized and sponsored by the Friends of the Clinton Library

Slope Stability and Vegetative Soil Stabilization
in the Puget Sound Region

Hosted by the University of Washington Botanic Gardens

Thursday, December 5, 2013

8:15 a.m. – 4:00 p.m.

University of Washington Botanic Gardens
Center for Urban Horticulture
3501 NE 41st St, Seattle, WA 98105

Cost:      $125 per person.  Lunch is included.
                ($150 after November 21)
Contact:  urbhort@uw.edu or 206-685-8033

Register: www.uwbotanicgardens.org/education

Who should attend: Professionals working with shoreline property, ravines, and other
topographically-challenged sites in the fields of engineering, planning, landscape design
and construction, horticulture, landscape architecture, ecological restoration, consulting,
arboriculture, and other land-management specialties.       

The topography of the Puget Sound region presents construction and management challenges with hills, ravines, coastal bluffs and shorelines
that can be subject to erosion and landslides in our rainy winter weather. This issue creates safety concerns, transit and
travel nightmares, permitting complexity, and questions about how to best design and construct in steep landscapes.

Land managers, planners, engineers, landscape architects and others need to know the most current information
about how water and geology interact, why the land moves, and what can be done to reduce erosion and promote stability.
This intermediate-level symposium offers an in-depth look at the hydrology and geology of our region, and the tools and techniques available to allow for successful slope stabilization.

 Speakers include:

  Bill Laprade, Senior Vice President at Shannon & Wilson, Inc. on Geology & Hydrology of Puget Sound.

  Elliott Menashe, Natural resource manager & consultant, Greenbelt Consulting, on Vegetation and Slope Stability and Vegetation in Conjunction with Engineering Solutions used to avert flooding, erosion, and landslides.

  Dr. Stan Boyle, Vice President at Shannon & Wilson, Inc., on Geosynthetics for Erosion Control and Reinforcement.

  Local governmental representatives will discuss permitting and regulations.

  Academics, public agencies, and contractors will present on current research and projects.

Living on the Edge

Bluff Management for Dungeness Homeowners

Wednesday October 30th, 2013

 6:00-8:00 pm at the Historical Dungeness Schoolhouse



The Coastal Watershed Institute (CWI) and partners invite the community to a bluff management workshop the evening of October 30th at the historical Dungeness Schoolhouse from 6:00 – 8:00 pm. 

This workshop will focus on management actions for bluff property homeowners and shoreline stewards in order to protect and preserve the habitat forming processes of the Dungeness bluff and spit system.  Clallam County will provide an update to the Shoreline Master Program (SMP), and Elliott Menashe from Greenbelt Consulting (www.greenbeltconsulting.com) will provide information about the role & value of vegetation and how bluff-shoreline landowners can reduce surface soil erosion and improve upland slope stability by improving their management practices.


CWI and partners, including Clallam County, Washington Department of Fish and Wildlife, Department of Natural Resources, Ecology, Earth Economics, and the Surfrider Foundation, are currently working together to better understand the bluff erosion processes and the ecosystem services of the nearshore, while defining best stewardship and wise long-term management actions of the central Strait nearshore.

 The October 30th workshop will be the second in a three workshop series provided for the benefit of our community and the environment. We hope you will join us!


The workshop is free but space is limited, so registration is required.  For more information and to register, contact:  Nicole Harris, 360-460-5092,


Funding for this work is provided by EPA, WDFW, Surfrider Foundation, Patagonia, and the Coastal Watershed Institute.

Menashe Presents, “Living on the Edge; Vegetation Management for Shoreline Property Owners” 

 Elliott Menashe will provide marine bluff and lake-shoreline property owners, ravine dwellers, and other topographically-challenged homeowners with helpful information about view management, reducing stormwater run-off and averting flooding, erosion, and landslides. Learn about zonal landscaping, bluff-top buffers, and the joys of using beautiful, eco-friendly, sustainable, and hardy native plants in your landscape designs. Through enlightened view-management choices, discriminating drainage management, inspired invasive plant control, and informed vegetation management, you can start solving tomorrow’s crisis today. An ounce of prevention is worth a ton of riprap.


So, whether you live on a small city lot or in the picturesque secluded hinterlands of the Salish Sea, come learn some crucial management tips that almost anyone can employ to reduce hazards and anxiety about their steep-slope property – before disaster strikes. You can (probably) live on the edge with lan … and peace of mind.
