www.wilson-architecture.com | 541-912-0878 Memo Project: Rosboro Plant Upgrades Subject: Site Review Application Project Description Date: March 26, 2024 From: Curt Wilson, AIA Note: This document has not been edited from the 2/26/2024 version included with the Pre-Submittal Application, except the items at the end of this document in response to the Completeness Review Checklist. Project Summary Rosboro intends to upgrade their glulam beam manufacturing capacity at their plant on Main Street west of 28 th Street. The upgrades include a new Planer Mill building at the current location of the former Plywood Building, and a new Glulam Beam building in the area of the former Dow Corning site. Site The mill site is currently comprised of three tax lots, and the site is zoned HI – Heavy Manufacturing and Production. The uses of the proposed new buildings are consistent with current site uses. Other elements of the plant will remain as is, including the staff parking lot that extends from 21 st Street and the internal circulation system from flows from the 21st Street extension to access points along 28 th Street. Utilities such as power, water, sanitary, and storm will connect to existing utilities on the site. This site is located in the Ten to Twenty Year Time of Travel Zone in the 16th and Q Wellhead Protection Zone. We anticipate submitting the Site Review application February 2024. There are currently 320 marked vehicle spaces on the site for employees and
City of Springfield Site Review Application Rosboro Plant Upgrades Wilson Architecture 3/26/2024 Page 2 visitors. 11 of these spaces are available to visitors in the north parking lot between Main Street and the main office building. As noted above, an additional 10 spaces will be added for customers at the east end of the Glulam Building. There are 309 spaces for staff parking, which is significantly more than the largest shift, therefore we do not plan to add parking spaces for employees. The proposed Glulam Building will span across two lots that are part of the overall plant site of the three total contiguous lots. Our proposed lot line consolidation process is as follows: Rosboro to propose a recordable Deed Restriction stating that “Parcel 1 and Parcel 2 of Reception No. 2016-060691 cannot be made separate transferrable parcels of land due to a structure encompassing both parcels, unless the building is removed and express permission to separate the parcels is given by the City of Springfield”. As an addition to this, as it is desired that the “Tax Lots” for these 2 parcels are combined into one “Tax Lot”, eliminating that “Tax Lot” line shown on your screenshot below, then Lane County has a Tax Lot Consolidation process. We acknowledge that when the Consolidation is done, the “legal lot” line does still exist. DWP Containment Requirements (SDC 3.3.200). The lamination process incorporates adhesives, therefore modest quantities will be stored on site and incorporated in the manufacturing equipment process (the equipment vendor selection process is ongoing, therefore Rosboro isn’t ready to commit to an adhesive type yet). An existing 48” sanitary line extends along the south edge of the west end of the property, and continues south presumably to serve properties along F St. Our survey indicates an easement at a manhole where the SS changes direction to the south. We intend to connect directly to the existing 48” SS on the property. Bike parking will be provided for staff within each building. Planer Mill The Planer Mill is approximately 72,000 sf. The building will be a Pre-Engineered Metal Building (Type II), fully sprinklered, one-story building. The building will be separated from other building on the site by 60 ft or more and located approximately 40 ft from the south property line abutting the railroad corridor.
City of Springfield Site Review Application Rosboro Plant Upgrades Wilson Architecture 3/26/2024 Page 3 A few offices, restrooms, and staff break area will be constructed within the middle area of the building. The building will house manufacturing equipment to size and surface rough lumber into finished lumber that will be used in glulam beams. Some of the equipment will be accessed from elevated platforms located more than 8 ft above the building slab-on-grade. The elevated platform will support a few partially occupied spaces including an enclosed equipment operator control room. The occupied spaces will be conditioned, therefore the enclosure around the occupied spaces will be insulated. The remainder of the Planer Mill will not be conditioned and open to the elements at the primary access locations. We anticipate submitting the building permit application in May 2024. Glulam Building The Glulam Building is approximately 150,000 sf. The building will be a Pre-Engineered Metal Building (Type II), fully sprinklered, one-story building. The building will be separated from other buildings on the site by 60 ft or more and located approximately 40 ft from the south property line abutting the railroad corridor. A portion of the building is envisioned as a showcase for glulam beams and mass timber construction. The concept is a covered entrance, tall-volume lobby with open stairs to an enclosed mezzanine level with a meeting room (less than 750 sf) and a modest executive office suite. The engineered wood products, including glulam beams, decking, and wood stair elements would be exposed highlighting various connection methods and bathed in daylight. Approximately 10 parking spaces will be located at the east end of the building for customer meetings held at the Glulam building executive meeting room. One accessible parking space and loading zone will be located closest to the entrance. We anticipate submitting the building permit application in August 2024.
City of Springfield Site Review Application Rosboro Plant Upgrades Wilson Architecture 3/26/2024 Page 4 Completeness Review Checklist Incomplete Items – Response Bike Parking Rosboro intends to provide bike parking for employees within the buildings. The attached floor plans identify the location of bike parking. If demand exceeds the number of spaces initially identified, Rosboro will expand the parking facilities. PW Notes – Industrial Pre-Treatment Program Rosboro is actively working with MWMC for the existing buildings and discharge and are compliant with the standards. We will continue correspondence with Sean Kruger on the new buildings. PW Notes – Stormwater Calculations These calculations are outlined in the updated stormwater report and align with discussion with Clayton. See attached stormwater report for further details. PW Notes – Additional Comments – Vegetated Treatment A vegetative treatment facility has been designed to treat the parking area east of the Glulam building. PW Notes – Additional Comments – Stormwater Operations and Maintenance Operations and Maintenance report to follow which will cover the entire Rosboro Campus. Transportation See application package for Trip Memo prepared by Sandow Engineering. Completeness Review Checklist Applicable Additional Items – Response Tree Felling Permit The existing trees in the area of the proposed improvements were significantly damaged during the January 2024 storms. Rosboro has hired an arborist to evaluate the trees and provided recommendations to address the damage. Some of the trees are more than 5 inches. The arborist report will be provided when available. We plan to add trees south of the new vegetative swale that is east of the Glulam Building. Overlay District – Drinking Water Protection We are working with SUB for containment procedures to comply with the DWP requirements. We anticipate the composition and quantity of adhesives used in the glue lamination process will trigger containment. The type of adhesive incorporated into the manufacturer has not been selected yet.
