Community Meeting

How will Riverbend blend with the natural landscape over time?

Photo simulations show how it will look from three viewpoints at three different stages of development

Basics: Design, Timeline, Aesthetics

Community Meeting

Three viewpoints

Three stages

• Today

• Five years after construction begins

• Fifteen years after construction begins

Seismicity and Seismic Design CriteriaHari Sharma, Ph.D., P.E.Geosyntec Consultants, Inc.

Community Meeting

• Requirements and Key Considerations

• Design Process

• Determination Magnitude 9.0

Seismicity – Requirements and Key Considerations

Probabilistic Approach – required

• Considers ground motions with 10% probability of exceedance (90% chance of not being exceeded) in 250 years

Deterministic Approach – beyond requirements

• Considers magnitude and consequences of 9.0 earthquake

Community Meeting

• Oregon DEQ, Solid Waste Landfill Guidance Document 2013

• US EPA, RCRA Subtitle D

• US EPA, Seismic Design Guidance for Municipal Solid Waste Landfills1995

• US Geological Survey, Seismic Hazard Maps 2014

• Oregon Resilience Plan - Report to the 77th Legislature, Oregon Seismic Safety Policy Advisory Commission 2013

Community Meeting Seismicity – Requirements and Key Considerations

Main types of seismic sourcesCrustal Faults• local, shallow seismic sources

Cascadia Subduction Zone • where the North American Plate collides with a number

of smaller plates

Cascadia SubductionZone

Community Meeting

Damage will be extreme in Tsunami Zone, heavy in Coastal Zone, moderate in Valley Zone, light in the Eastern Zone. Riverbend is in Valley Zone.

Oregon Resilience Plan – 9.0 scenario

Approximate Site Location

Community Meeting

Design Process - Proposed Expansion GradesCommunity Meeting

Design Process – conventional Berm

Community Meeting

Community MeetingDesign Process – slope design maximizes stabilityand minimizes floodplain impact

Design Process

Expansion design will address:

• Static Forces

• Seismic Loading

• Liquefaction

Community Meeting

Summary – Magnitude 9.0• Riverbend is in a region of moderate damage potential

from seismic activity – damage to furniture and poorly built masonry structures, etc.

Community Meeting

• The expansion design will meet seismic design regulations and considers new guidance documents

• The expansion design will meet Magnitude 9.0 seismicstandard (Oregon Resilience Plan)

• The expansion design will resist seismic forces and protect the integrity of the site’s environmental systems

Floodplain Impacts and EnhancementShane Latimer, Ph.D., CSELatimer Environmental LLC

Community Meeting

• Regulatory Framework and Requirements

• Design

• Determination minor encroachmentwith no rise overall

Regulatory Framework

• Regulatory environment is complex and important to ensure health of wetlands and local ecosystem

• Permits are required for all work related to floodplain impacts and enhancements

• Floodplain Development Permit process ensures our proposal meets all requirements

Community Meeting

Regulatory Framework

• Local jurisdictions are responsible for regulating development and issuing permits in “flood hazard areas”

• Federal Emergency Management Agency (FEMA) administers the National Flood Insurance Program, but does not have a direct role in local land use processes

Community Meeting

Requirements

• Avoid and minimize floodplain fill; avoid raising100-year flood elevation

• Avoid wetlands as practicable; minimize and compensate for unavoidable impacts

• Comply with all applicable local, state, and federal environmental regulations

Community Meeting

Community Meeting Project Orientation

Design Objectives

• Avoid high quality riparian areas and wetlands

• Restore the southern tributary creek to a more natural state

• Enhance fish and wildlife habitat (uplands and wetlands)

• Compensate for wetland fill

Community Meeting

Determinations

• Proposed design includes minor encroachments into the floodplain

• Engineering analysis indicates no-rise as a result of our proposed project

• Project will enhance about 3.8 acres of the southern tributary and compensate for the floodplain fill associated with Module 11

• Project will comply with all applicable local, state, and federal environmental regulations

Community Meeting

Farm Impact Assessment Jay Harland, Principal CSA Planning Ltd.

Community Meeting

• Requirements and Purpose

• Methodology

Farm Impact Assessment Jay Harland, Principal CSA Planning Ltd.

Requirements and Purpose

Community Meeting

• Critieria - ORS 215.296(1)

• Purpose is to address criteria so Yamhill County can evaluate theproposed expansion in relation to farm and forest practices in the area

Farm Impact Assessment - MethodologyCommunity Meeting

• Identify farm uses on surrounding lands

• Define farm practices associated withidentified farm uses

• Identify landfill characteristics withpotential to affect farm practices

5 November 2014 34

Farm Impact AssessmentCommunity Meeting

• Assessment evaluates impacts geographically

• Reviews historical aerial photos to assess changes in farm use over time

• Entire assessment and all supporting data included in application

Community Meeting

Select a topic: design-timeline-visuals, seismicity, floodplain, farm impacts

55 minutes, at least three rounds

New round, join table

May move around to different tables to observe

Small Group Discussion(note sheets and comment cards)
