Plain-language summary
Metro picks larger design for new Cornelius garbage and recycling drop-off site
Metro plans a new drop-off site in Cornelius where people and small businesses can bring household hazardous waste, recycling, reusable items and garbage. The council chose the larger 7-acre design, called Option B, which has more space for reuse, community events, green space and future growth. A small temporary site for household hazardous waste would open first while the permanent depot is designed.
Decision: Passed, 6 to 1. Mary Nolan voted no.
Who it affects: Washington County residents and small businesses, with the share of county residents within a 20-minute drive of a full-service depot expected to rise from 5% to 40% when the depot is finished.
Money: The larger design is estimated at about $23 million to build, compared with about $17 million for the smaller option. The temporary hazardous waste site is estimated at about $3 million, paid from Metro waste revenues and reserves. Staff expect to pay for the permanent depot with revenue bonds (borrowed money repaid from fees), but this vote does not approve borrowing or construction.
Next: Staff will continue design and engineering and update the council from time to time. Final design, cost, borrowing and construction need later council votes. The City of Cornelius Planning Commission must also approve land use permits after a public hearing.

Executive Summary
Background
Metro is interested in developing a community drop o!
depot in Washington County on a vacant approximately
12-acre site that they already own. This new facility will
provide easier access to self-haul and recycling services
for nearly 120,000 residents.
The depot is anticipated to be constructed in two phases,
with an approximately 1-acre interim facility established
" rst using minimal site improvements and temporary
structures to allow for a quicker build-out and focus on
providing needed household hazardous waste (HHW)
services to nearby residents. The next phase would be
a full build out with a permanent household hazardous
waste structure, self-haul garbage collection, expanded
recycling areas, and community amenities. The design
team provided two options for the full build out in varying
sizes: a 4.75-acre and a 7-acre option.
Land Use
Based on conversations with the City of Cornelius, future
development of the property will require approval a Type
II Minor Land Partition (MLP) to divide the property, a
Conditional Use/PUD permit and a Site design review
through a Type III land use review to obtain approval of
the phased improvements. The Type II MLP can be run
concurrently with the Type III development reviews. The
land use approvals would take approximately 4-6 months
and require a public hearing and approval by the City of
Cornelius Planning Commission.
Civil Engineering
The existing site is relatively #at, has public utilities nearby,
and there are no major impediments to development
from a civil engineering standpoint. Access will be
granted to N 4th Avenue in the interim phase, with full
access potentially via a N Holladay Street extension
for the second phase of development. There is likely
a requirement at full-buildout to extend a new public
roadway (N Holladay Street) along the north boundary
of the subject site. The future roadway section would be
constructed from the west edge of the Mendoza property
to a proposed partitioned property line of the subject
property. There is existing public water and sanitary
sewer nearby and they are at typical and su$cient depths
for development in each phase. Stormwater for the
development will be managed on-site within vegetated
facilities and can be adequately phased and discharged
to the existing public stormwater system in N 4th Avenue.
Site Preparation and Stripping
Per the Phase II ESA and the geotechnical report, the
existing site contains nuanced recommendations for site
stripping. The geotechnical report recommends the top
layer of soil and organic material (typically 4-8 inches,
but potentially up to three-feet) shall be removed from all
proposed structural areas (e.g. pavements and structures)
prior to construction. Furthermore, the Phase II ESA
notes that the top 6-inches of soil exceeds the Oregon
DEQ Clean Fill levels for herbicides. Therefore, the Phase
II ESA recommends that the top 6-inches of stripped
soil can either be reused on site or hauled away and
considered solid waste. If the material is reused on-site it
would require a solid waste permit with Oregon DEQ and
may only be used in non-structural areas (not beneath
pavements or structures).
Executive Summary1
Metro ▪ Cornelius Community Drop-Off DepotSEA ▪ HHPR ▪ JRMAInterim Concept
The approximately 1-acre interim household hazardous waste layout is optimized to bring services to the community as
soon as possible. It has temporary canopy structures that are supported by pre-fabricated, mobile elements to create
the storage and drive-thru household hazardous waste areas, and a trailer for employee support spaces. Access is
from 4th avenue with the service area set back from the roadway to allow for queuing space and landscape buffers.
The layout for the interim facility varies depending on the option selected for the full depot buildout, as both options are
coordinated to allow drive entrances, utility runs, and paved areas to be reused in the next phase without significant
rework or demolition. Both interim options are also located to allow construction on the permanent household
hazardous waste building to begin while the interim facility can remain operational.
Interim Summary:
Site Area: 1 acre
Services: Household Hazardous Waste
2026 Project Estimate: $2,985,029 (excludes equipment)
can be adequately phased and discharged to the existing public stormwater system in N 4
Avenue.
Interim Concept
The approximately 1-acre interim HHW Layout is optimized to allow for quicker
construction to bring services to the community as soon as possible. It has temporary
canopy structures that are supported by shipping containers to create the storage and
drive-thru HHW areas, and a trailer for employee support spaces. Access is from 4th
avenue with the site set back from the roadway to allow for queuing space and landscape
buffers. The layout for the interim facility varies depending on the option selected for the
full depot buildout, as both options are coordinated to allow drive entrances, utility runs,
and paved areas to be reused in the next phase without significant rework or demolition.
Both interim options are also located to allow construction on the permanent HHW
building to begin while the interim facility can remain operational.

Metro ▪ Cornelius Community Drop-Off DepotSEA ▪ HHPR ▪ JRMAConcept A (Compact Depot) – 4.75 Acres
The 4-acre concept for the Cornelius Community Drop-Off Depot provides a full range of services with a permanent
household hazardous waste structure and an adjacent employee building that will also offer space for community
partners. Special attention was paid to circulation throughout the site and reducing interaction between public and
operational traffic. There are two entrances off 4th Avenue for paid and non-paid customers. The household
hazardous waste is located in the northeast corner of the site close to 4th Avenue as a feature and entrance to the
site, with visitor parking located adjacent to it. The household hazardous waste features a covered area where
attendants will unload hazardous materials and a bypass lane that allows direct access into the free recycling and
reuse areas. Storage bins for various recyclable items and materials are located on large islands that will be covered
by canopies for shelter weather protection.
The second entrance to the site is for paid customers that will travel past the scale house and scales to access the
raised self-haul garbage area for garbage and paid recycling drop-off areas. After dropping off materials they will exit
down the ramp past the scale house and exit the site.
Operational traffic, roll-off trucks and trailers, etc, is kept on the outer edges of the site, and segregated from the
public for safety and efficiency. A separate entrance is provided for operational vehicles located either off 4th Avenue
near the south of the site or to the north with access from N. Holladay, depending on street dedication and the status
of site improvements on a neighboring parcel north of the site.

Metro ▪ Cornelius Community Drop-Off DepotSEA ▪ HHPR ▪ JRMAConcept B (Optimized Depot)– 7 Acres
The 7-acre concept for the Cornelius Community Drop-Off Depot provides more area and capacity for material
processing as well as allowing for future expansion. This option also provides more community amenities, notably open/
park space for community events, a sustainability plaza that provides educational opportunities about recycling and a
potential showcase for artists using recycled materials. These enlarged landscaped areas also provide a visual buffer to
the site and could function as an amenity or rest stop for the nearby Council Creek Regional Trail.
Both the household hazardous waste building and the employee & community building have a larger footprint in the
7-acre option, with space provided for HHW future expansion. Like Concept A, traffic is divided between paying and
non-paying customers with the north entrance off 4th Ave providing direct access to the scale complex and self-haul
garbage area with extended queuing space.
The south entrance provides direct access to the household hazardous waste, community building, and visitor parking.
The self-haul garbage area is pushed to the west end of the site and oriented along a north-south axis with truck,
operational vehicles, and employee parking all assumed to enter and exit the site from N Holladay St.
The center of the site holds the reuse and recycling areas with a large reuse building to sort and store reusable items
and the recycling bins are stored under large canopies. To increase sustainability, the canopies will be outfitted with
photovoltaic panels and (3) large above ground cisterns will be provided for rainwater harvesting. Harvested water can
be used for facility washdown or irrigation during dryer months.
As in the previous concept, special attention was paid to traffic flow, queuing space, and separation of public vehicles
from operational traffic.
