Site Review Narra�ve This narra�ve is for a site review applica�on for a proposed mul�-building development including retail, office-space, carwash, and drive-thru loca�ons. Midtown Plaza is located at the southwest corner of Main Street and 32nd street in Springfield, Oregon. There is an exis�ng retail building on the north end of the site that is proposed to remain with 65 exis�ng parking spaces. In addi�on, the proposal is to construct a carwash facility that includes 21 short term vacuum parking spaces for vehicles, a drive through coffee kiosk, and three addi�onal office/retail buildings ranging from 3,119 square feet to 6,680 square feet. Owner/Applicant Westgate Plaza LLC Atn: Ryan Mckillop 3700 Coburg Rd Eugene, OR 97408 (541) 514-4398 Applicants Representa�ve A & O Engineering LLC Kyle Morris, PE 380 Q Street, Ste 200 Springfield, OR 97477 (541) 302-9790 kylemorris@ao-engr.com Project Loca�on Address: 130 S 32nd Street Springfield, OR 97478 Tax Lot: 17-02-31-00 T.L. 501 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. PARKING SITE DATA PRE-CONST POST-CONST Total Spaces 65 136 Total Reconfigured Exis�ng Spaces - 11 Total Spaces Proposed - 71 Total Vacuum Spaces - 21 Total Proposed Standard Spaces (Non-Vacuum) - 61 Total EV Spaces Required (40% of New Spaces) - 24 Total EV Spaces Provided - 24 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.
