Project Description:
This application is for site plan approval of a new 1,485 square foot addition to the existing 8,767 square
foot (not including overhangs) Oregon Urology Institute Radiation Center. The original development for
this site was approved by Site Review Application #DRC2007-00009 on February 28, 2007. The
previously approved site plan indicated the addition that is proposed in this application. The total property
area is 41,112 square feet and will not change due to the proposed addition. Only the site immediately
adjacent to the new addition will be modified as noted in this application.
Project Location:
The project site at 1457 G Street is located on the south side of the 1400 block of G Street between 14th
and 16th Street. The existing Oregon Urology Institute Radiation Center is a flag shaped property
comprised of two tax lots on Map #17-03-36-22. The flag portion of the property is Tax Lot 6800 facing G
Street. The flagpole portion of the property is Tax Lot 7000 at the southeast corner of the flag property

Final Site Plan Review Narrative April 17,2023
Project Use:
The facility is a combined radiation and immunotherapy clinic with associated offices. The total number of
full-time equivalent employees is 8 with a couple of per-diem employees. The number of employees is not
anticipated to change with this addition.
Hours of Operation: Normal operating hours will range from 8:00 AM to 5:00 PM, Monday through Friday,
except holidays.
Zoning:
The site is within the Springfield City limits and is zoned GO, General Office. The site is designated within
the Hospital Support Overlay Zone. A medical office building use is a permitted outright in both the
General Office Zone and Hospital Support Overlay Zone.
Adjacent Uses:
The property to the east along G Street is zoned Low Density Residential. That property is currently the
McKenzie Willamette Hospital employee parking lot. The properties to the west along G Street are zoned
Low Density Residential. G Street Integrated Health, a medical provider facility, extends to 14th Street.
The property to the north, across G Street, is zoned Mixed Use Commercial and is the McKenzie
Willamette Hospital. The two properties to the southwest are zoned Low Density Residential. The
easternmost of those properties is vacant and the westernmost of those properties contains a single-
family residence.
Hospital Support Overlay Zone:
The purpose of the hospital support overlay zone is to provide, among other things, hospital related
support services. The urology radiation center meets this criterion. The design standards for the Hospital
Support Overlay Zone noted in Springfield Development Code Section 3.3.1125 are as follows:
(1) All yard, lot/parcel size, coverage, density, fencing, parking standards shall be subject to the
same standards as professional offices in residential districts.
Per City of Springfield Development Code Section 4.7.190 Professional Offices in Residential Districts:
(A) Professional offices in residential districts are permitted when:
(1) The lots/parcels are adjacent to CC, MUC or MRC Districts; and
The property is located adjacent to the Mixed Use Commercial district located to the
north, across G Street.
(2) The majority of the square footage of the structure on the lot/parcel is not more than 100
feet from CC, MUC or MRC Districts. Where public-right-of-way separates the
residential district from the commercial district, the right-of-way width is not counted in
the measurement.
The main frontage of the building is located 65’ from the north property line.
(B) A professional office exceeding 2,000 square feet of gross floor area shall abut an arterial or
collector street.
The main frontage of the building faces G Street which is a collector street.
(C) No parking shall be permitted within the front yard setback. Required parking shall be screened
from the public view.
No parking is located within the front yard setback. All parking along the side and back yards are
screened from the adjacent residential zones with fully established arborvitae hedges. The
hedges were planted during the initial construction of the building in 2005.

Final Site Plan Review Narrative April 17,2023
(D) For structures on the Springfield Historic Inventory, any external modification shall be fully
compatible with the original design.
The building is not on the Springfield Historic Inventory.
(E) Professional offices permitted are limited to: accountants, architects, attorneys, computer
programmers, designers, engineers, insurance agencies, investment counselors, licensed real
estate agents, medical and dental practitioners, counselors, planners, and studios for artists,
interior decorators and photographers, and similar general office uses engaged in support
services to their businesses and/or their parent companies.
A professional office used for medical practitioners is a permitted use.
(F) A minimum of 25 percent of the lot/parcel shall be landscaped
The landscape area covers 11,494 square feet (27%) of the 41,112 square feet total lot area.
(2) A minimum of 25 percent of the lot/parcel shall be of planted material.
The landscape area covers 11,494 square feet (27%) of the 41,112 square feet total lot area.
(3) Parking lots shall meet the planting standards applicable to commercial development.
All off-street vehicle parking will conform to the standards listed in SDC Sections 4.6-110 through 4.6-120.
Site Access / Public Transportation:
Primary site access is provided along G Street. Public transportation is available from a bus stop 0.2
miles to the west of the site along G Street. A second bus stop is located near the emergency room
entrance of the McKenzie Willamette Hospital along Mohawk Boulevard, also 0.2 miles from the site.
According to Lane Transit District, no additional transit stops are planned within 1/2 mile of the property.
Traffic Impact:
According to the Institute of Transportation Engineers (ITE) Trip Generation Manual, the average daily
trips for a medical office is 36 per 1,000 square feet. At 10,252 sf (including the addition but excluding
roof overhangs), this ratio results in 369 daily trips. The ITE’s peak hour trip rate for medical offices is
4.79 per 1000 square feet. This results in 49.1 peak hour trips. Both numbers are well below the threshold
to require a traffic impact study.
Off-Street Parking Facilities:
The property has two separate parking lots. The north parking lot is accessible along G Street and
connected to the main entry of the building. The north parking lot has 22 standard parking stalls and 4
accessible parking stalls. The 4 accessible parking stalls are located closest to the building’s entry. The
south parking lot has 12 standard parking stalls with access from F Street. This is a total of 38 parking
stalls.
According to SDC 4.6.125, the 10,252 building (including addition but excluding large roof overhangs)
requires a minimum of 34 parking stalls at 1 stall per 300 SF of building area). Since there are no planned
changes to the parking lot area, the project does not propose any revision to the number of parking stalls.
Bicycle Parking:
The building area after the addition is 10,252 SF (excluding large roof overhangs). According to SDC
4.6.155, 0.75 bicycle parking stalls are required per 5,000 SF of building area. This results in two (1.54
calculated) required parking stalls. One short term (0.39) and one long term (1.15) parking stalls are
required. There are 18 existing ribbon style bicycle parking stalls located under the building’s northeast
covered area. There is a sidewalk connecting the bicycle parking stalls and the public right-of-way along
G Street. The new project does not propose any changes to the bicycle parking.
Phased Development:
The addition to the building and the associated site work will be completed in one phase.

Final Site Plan Review Narrative April 17,2023
Exterior Lighting:
The existing light poles and building mounted exterior lights were approved in the site review application
for the original building. No modification to existing lighting or addition of new lighting is proposed.
Utility Infrastructure:
The existing site development includes connections to power, natural gas, storm water, domestic water,
and fire protection water lines. Refer to attached Sheet C3.0 of the original construction documents. The
existing connections have been found to be sufficient to support the new addition.
Easements:
Refer to the existing conditions plan for description of the existing easements associated with the project.
No changes are proposed for the easements.
Stormwater Management:
The existing stormwater treatment on this site was previously approved on the Site Review Application
#DRC2007-00009. The new stormwater treatment that we propose only addresses the impervious
structure from the new addition.
Wetlands:
The property is not in areas identified in the Springfield Local and National Wetland Inventory Map.
Drinking Water Overlay District:
The site is within the 10-year and 20-year time of travel zones as shown on the City of Springfield’s
Wellhead Protection Area Map. No additional hazardous materials will be present on site due to this
addition. While the clinic portion of the building is sprinklered, no sprinklers are proposed within the
addition. The property is currently engaged in a drinking water protection agreement with the Springfield
Utility Board and will maintain the terms of this agreement.
Signs:
No changes to existing exterior signage is proposed.
