Project Description (Include a copy of Assessor’s map):
Proposed commercial development with multiple retail spaces, shared parking lot, and private internal sidewalks.
Drainage Proposal (Public connection(s), discharge location(s), etc. Attach additional sheet(s) if necessary:
Based on Web Soil Survey, the infiltration rates are between 0.20 – 0.57 in/hr and are classified as soil group C. Assuming
poor infiltration rates are verified through testing, on-site filtration facilities are proposed before discharging into the public
storm system.
Proposed Stormwater Best Management Practices:
The proposed filtration facility could be a filtration rain garden that detains and treats all runoff from impervious
areas before discharging into the public system.

Exis�ng Use of Site
There is an exis�ng retail building on the north side of the property that currently houses several
businesses. The site also has 65 exis�ng parking spaces and stormwater facili�es to serve the exis�ng
mul�-tenant retail buildings. There is an exis�ng reciprocal parking agreement with the Bob Keifer Sports
Center adjacent to the subject property.
Proposed Use
The applicant is proposing to construct two mul�-tenant retail buildings and one office building ranging
from 3,119 square feet to 6,680 square feet. The proposal also includes a new coffee kiosk with drive-
thru and a car wash that includes 21 short-term vacuum spaces. There will be three shared trash
enclosures on site serving the surrounding buildings. The loca�ons of these trash enclosures are shown
on the site plan.
The site will be accessible via an exis�ng driveway access from 32nd street with shared access from the
Bob Keifer Sports Center. Site access is shown on the site plan.
The development is proposed to be constructed in 4 four phases. See site development plan for more
detail.
Phase 1 – Carwash 2024
Phase 2 – Coffee Kiosk/Drive-thru 2024
Phase 3 – Mul� Use-Retail Buildings 2025
Phase 4 – Mul� Use-Retail Buildings 2026
Land Use
The parent zone of the property is Community Commercial
The land use of the abu�ng proper�es are:
North: Light, Medium Industrial – Eastern Lane Forest Protec�ve Associa�on
Community Commercial – Oregon Department of Human Services
East: Community Commercial - Bahenas Family Auto Sales
South: Public Land & Open Space - Bob Keifer Sports Center
West: Community Commercial - Autozone Auto Parts
The proposed project meets the land use requirements of the development code given the abu�ng 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. See Sheet C-2.0 for reference.
Four phases are proposed as part of this development to be constructed in three years. See above table
for reference. The future development area is not included in this site review applica�on.
Site Access – Infrastructure/Transporta�on – 4.2
The applicant will be submi�ng a traffic study as part of this submital.
No new streets are proposed as part of this submital. There is one exis�ng street access to the site off
32nd Street which will be u�lized for the new development. The access is proposed to remain but be
altered to a standard commercial driveway with setback sidewalk. A new catch basin is proposed to be
installed in front of the driveway to replace the exis�ng curb inlet within the exis�ng radii at the
driveway. There is exis�ng access from the Bob Keifer Center on the south side of the site. There is an
exis�ng reciprocal parking agreement with Willamalane that encourages site access from both ways.
See the project plans for more informa�on.
Infrastructure Standards – U�li�es – 4.3
Grading
The proposed site will be graded to direct stormwater away from the buildings and into nearby catch
basins throughout the site. These catch basins are already connected to the public system and no new
stormwater connec�ons to the public system are proposed. The remainder of the site will be graded to
match exis�ng drainage paterns as well as eleva�ons of adjacent proper�es.
There are no wetlands or riparian areas located on site. The proposed lot is located inside the 10-20 year
�me of travel zone. Surfaces for vehicular use are proposed to be hard surface with either asphalt or
concrete. Stormwater will be directed to vegetated treatment facili�es to provide pollu�on control prior
to leaving the site and entering the public system. The one exis�ng swale on-site is proposed to be
reconfigured slightly and re-planted to meet current requirements. Mul�ple other stormwater planters
are proposed on-site to treat and detain new impervious surfaces. In all stormwater facili�es infiltra�on
is proposed to be u�lized as much as possible for discharge. Details are outlined on sheets C-3.0 and C-
4.0 and in the full stormwater report included with the submital.
Domes�c water is proposed to each of the new buildings. For each building a new water meter and
backflow device is proposed with private piping then to be constructed. The final water meter and
backflow configura�ons will be reviewed by SUB Water during the building permit process. See the
project plan for detailed informa�on.
With the current fire hydrant configura�on that is available to the property fire sprinkler systems are not
required on-site. No new fire hydrants or fire sprinkler systems are proposed with this project. See the
project plans for detailed informa�on.
Exis�ng sanitary sewers on-site are proposed to be u�lized for the new buildings. No new connec�ons to
the public system are proposed with this project. See the project plans for detailed informa�on.
Franchise u�li�es (Electric, Phone, Cable, Natural Gas) are located on Sheet C5 and C6 where preferred
loca�ons for electric, phone, cable, and gas meters to serve the development are shown. Franchise
services will be designed by the providing u�lity companies during the building permit process. U�li�es
will be placed underground.
Landscape, Screening and Fence Standards – 4.4
We are not removing more than 5 trees, therefore no tree removal permit is required
The plan�ng plan for the site (including stormwater facili�es) is outlined in the landscape sheets of the
plan set. The plan�ng in the stormwater facili�es meets the requirements outlined in the Eugene
Stormwater Management Manual. DLA prepared the landscape sheets for this submital.
The frontage along Main Street and 32nd Street has exis�ng street trees that were planted during
construc�on and are proposed to remain.
On-Site Ligh�ng Standards – 4.5
Ligh�ng standards are addressed on the architectural sheets included with this submital.
Site ligh�ng is proposed on-site with both pole ligh�ng and wallpack loca�ons. Exis�ng pole ligh�ng is
proposed to be updated with new fixtures. See sheet E-000 for the proposed ligh�ng on-site.
Photometrics were also prepared for this site and are included with this submital.
Motor Vehicle Parking, Loading, and Bicycle Parking Standards – 4.6
According to OAR 660-012-0440, there is no parking required in sites within 0.5 miles of a frequent
transit corrido. Therefore, there is no new parking required as part of this development. According to
LCDD 660-012-0410 Electric Vehicle Charging, new mixed-use buildings consis�ng of privately owned
commercial space shall require the provision of electrical service capacity, as defined in ORS 455-417, to
accommodate 40 percent of all vehicle parking spaces.
There are 65 exis�ng spaces on site that are proposed to remain. 71 new spaces are proposed as part of
this development with 21 of these spaces being short term vacuum spaces. These spaces are intended
for temporary parking (approximately 5 minutes) while customers ac�vely vacuum their cars, therefore
they were not considered in the EV charging space requirement calcula�ons.
136 total spaces for the development with 6 ADA parking spaces provided. No Loading zones are
proposed as part of this development.

Specific Development Standards – 4.7
Sec�on 4.7.100 of the Springfield Development Code is not applicable to this proposal because the
proposal fits within 4.1.100-4.6.100 standards without any special use.
Temporary Use Standards - 4.8
There are no temporary dwellings proposed as part of this development, therefore the Temporary Use
Standards in sec�on 4.8 are not applicable to this development.
Building Eleva�ons
Preliminary building eleva�ons for the buildings have been included with the submission packet. See
sheets prepared by Robert Coryell Design.
Site Sign Standards
A monument sign is proposed at the entrance of the proposed site, as well as a direc�onal site located
on the main drive. The signs on the individual businesses will be in compliance with the Springfield
Development Code.
The exis�ng monument sign at the corner of 32nd and Main Street is proposed to be removed and a new
monument sign for the whole development constructed. The proposed square footage of this sign is
approximately 77 square feet on each side or 154 square feet total.
For the carwash facility a monument sign (reader board) is proposed. This sign is approximately 70
square feet on each side or 140 square feet total.
An overhead entrance sign is proposed over the main drive entrance. The purpose of this sign does not
adver�se any specific business on the property but add an architectural feature that is invi�ng to the
property.
Interior to the site a double monument sign is proposed just south of the exis�ng bioswale. The purpose
for this sign is direc�onal to traffic already on the property and is not intended to adver�se to vehicles in
the public ROW. The approximate square footage of this sign is 85 square feet on each side or 170
square feet total.
There are also signs proposed on each building. Those are summarized on the plan sheets that were
included with the submission.
