Site Review Narrative
This narrative is for a site review application for a proposed multi -tenant industrial building on
Parcels 7 and 8 of J.P. Hammer Industrial Subdivision, which is located at the southeast corner
of 40t' Street and Kathryn Street in Springfield, Oregon. The proposal is to construct four
buildings ranging from 6,099 square feet to 11,964 square feet with associated infrastructure.

Project Location
Address: No Address Assigned
Tax Lot: 17-02-30-44 T.L. 300,400
Existing Use of Site
The project site is currently vacant of any buildings. There is an existing joint driveway to serve
the Aramark Development at the southeast corner of Lot 7 in an existing joint access easement.
Proposed Use
The applicant is proposing to construct four multi -tenant buildings with associated
infrastructure. There is not an identified tenant. There is one proposed loading dock (truck well)
to serve the development on the west side of building one.
There will be a shared trash enclosure within building three of lot 8 which serves all of lot 8. Lot
7 will have a shared trash enclosure within building one which will serve all of lot 7. The
locations of these trash enclosures are shown on the site plans.
The site will be accessible through existing entrances on the north side of Lot 8 (Kathryn Street)
and the southeast corner of lot 7 as shown on the site plans.
The proposed site is within the Mid -Springfield Development Plan. Our proposed use is within
the parameters of the Mid -Springfield Development Plan.
Land Use
The parent zoning of the property is heavy industrial.
The land uses of the abutting properties are:
North: Heavy Industrial - Existing industrial development
East: Heavy Industrial - 40' Street - Lot 10 across street (vacant)
South: Heavy Industrial - Heavy Industrial — Aramark -
West: Low Density Residential - 36th Street
The proposed project meets the land use requirements of the development code given the
abutting land use zoning and uses.
The setbacks required for the project are 10 feet from the property lines, which have been
provided in the proposed project.
Site Access
There are two existing accesses to the site which were constructed during the PEPI project
associated with the J.P. Hammer Industrial Subdivision. There is a joint driveway shared with
Aramark to the south, on Lot 7. This access is proposed to remain, utilizing existing grading and
drainage patterns. The second access is a curb cut on Kathryn Street adjacent to Lot 8.
Grading
The proposed site will be graded to direct stormwater away from the buildings and into nearby
catch basins throughout the site.
The remainder of the site will be graded to match existing drainage patterns as well as
elevations of adjacent properties.
Wastewater System
The buildings are proposed to be served by a new wastewater pipe system that will plug into
existing stubs adjacent to the lots as shown on the utility plan. The lines will be routed to serve
each potential lease space individually and be extended to tie into the area drains proposed in
the trash enclosure and loading dock.
The trash enclosure area will be covered with the concrete base graded to be hydraulically
isolated.
The existing mainline and stubs from Industrial Avenue were constructed as part of the PER
project related to the J.P. Hammer Industrial Subdivision.
Floor drains tied to the wastewater system are proposed to be located just inside the building at
each overhead door location.
Storm Water Svstem
The site is located in the J.P. Hammer Industrial subdivision which includes 3 +/- acres of
detention ponds to serve all of the parcels. Lots 7 and 8 discharge stormwater runoff into these
detention ponds. The post -construction peak stormwater runoff was found to be 1.73 cfs during
a 10 -year, 24-hour storm event.
The drainage systems for Lot 7 and 8 are outlined below:
Paving across both lots is proposed to be graded towards catch basins, forming a collection of
basin areas. See the basin map shown on site plans for more information. Within this basin
map, basins 7, 11, 13, 14, and 15 will see the stormwater runoff be mechanically treated prior to
discharge into the storm main connection on the east side of Lot 7. Stormwater runoff from
basins 10 and 12, which are composed of the roofs of the buildings proposed to be built on lot 7,
will be routed into the same pipe system as the mechanically treated stormwater runoff before
being discharged into the same storm main connection for Lot 7.
The basin areas 1, 2, 3, 5, 8, and 9 will instead be vegetatively by flowing through a drainage
system into the proposed stormwater planter on the northeast corner of Lot 8. From there, the
stormwater will be treated prior to discharge into the storm main connection on the north side of
the northeast corner of Lot 8. Basin areas 4 and 6, which are composed of the roofs of the
buildings proposed to be built on Lot 8, will be routed around the stormwater planter to
discharge directly into the same storm main connection for Lot 8.
Water System
The proposed water system is to install individual domestic water meters on the east side of the
building, where the existing water line is located in a public utility easement. Both lines will then
be routed through approved backflow systems and will be routed to separate portions of the
proposed building.
There will also be a %" branch line that will be extended to the trash enclosure to provide water
for a yard hydrant and to prime the trap for the area drain.
There are existing fire hydrants located north and south of the property. There is an existing
hydrant on the north side of Olympic Street at the intersection with 40" Street (approximately
197' north of building). There is another hydrant located on the west side of 40� Street which is
located approximately 209 feet south of the building. A separate sprinkler system for the
building is not proposed.
The final design of domestic water lines will be completed during the building permit process.
Site Lighting
The proposal is to install recessed downward facing TWR1 LED lighting on the exterior of the
building, directed down to light the sidewalk and pavement areas adjacent to the structure. Pole
lighting locations are shown on sheet C-3.0 with fixture details on sheet C-6.0
Photometric analysis is included with this submittal and shows no light trespass across exterior
property lines.
Landscape
We are not removing more than 5 trees, therefore no tree removal permit is required.
The planting plan for the site (including stormwater facilities) are outlined on sheets LA -1 and
LA -2 of the plan set. The planting in the stormwater facilities meet the requirements outlined in
the Eugene Slormwater Management Manual.
The frontage along Kathryn Street and 40' Street has existing street trees that were planted
during the public improvement project for the subdivision.
Drinking Water Protection
The proposed lot is located inside the 2-5 year time of travel zone and 5-10 year travel zone for
drinking water protection. The area where vehicles will be driving will be paved. Storm water
will be directed to two types of facilities to provide pollution control treatment prior to entering
the existing detention pond system. Details are outlined on the plan sheets. Wetland protections
notes are listed on Sheet 2.0
The stormwater planters will include 18 inches of soil media to meet the requirements in the
drinking water protection area.
Site Soils
Malabon Urban Land Complex is generally described as hydrologic soil group C. The expected
infiltration rate of this soil is approximately 0.5 inches per hour, which will allow the landscape
areas to drain.
The stormwater planter is lined, so no infiltration is planned for that facility.
Franchise Utilities
Franchise Utilities (Electric, Phone, Cable, Natural Gas) are located in the Kathryn Street and
40" Street rights of way adjacent to the project. Sheet C4 shows the preferred location for
electric, phone, cable, and gas meters to serve the development.
Franchise services will be designed by the providing utility companies during the building permit
process.
Building Elevations
Preliminary building elevations for the building are shown on the architectural plan sheets
provided by Rodd Hansen Architecture.
