Memo
Project: Rosboro Plant Improvements
Subject: Drinking Water Protection Permit – Scope of Work Description
Date: October 25, 2024
From: Curt Wilson, AIA
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, 72,000 sf (at the current
location of the former Plywood Building), and a new Glulam Beam building, 150,000 sf 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.
The Site Review application wa
submitted February 2024 and final
approval is expected soon.
Construction of the Planer Mill is
underway. The building permit
application for the Glulam Building is
scheduled to be submitted December
2024.

The new buildings will
increase Rosboro’s
capabilities to produce
beams from logs on their
current site. Debarked logs
will be milled into boards at
the Planer Mill, the boards
will be dried in exiting kilns
and brought to the Glulam
Building where they will be
physically joined together at
the ends and adhered
together into beams.
Containers of lubricants,
paints, and other materials
currently used in other mill
buildings on site will be
stored in the Planer Mill to
maintain the equipment.
The containers are 55-
gallon drums or smaller and
all containers will include a
containment tray when
delivered to the site, as
moved through the building,
and as placed near
equipment for use.
The Glulam Building will
have similar materials for
maintenance with the same
handling protocols. In
addition, adhesives are an integral part of the process to create the beams. Multiple types of adhesives
are utilized, some will be delivered and stored in drums with self-containing trays. The most commonly
used adhesive is stored in a tank. The tank will either include a self-contained tray, or a site-built
containment system will be incorporated with the improvements. The tank will be filled from a delivery
vehicle that will be parked on the south side of the building.
Rosboro has well-developed procedures for safe handling of materials that are shared with employees
and vendors and a management plan associated with physical containment facilities. For the adhesive
delivery vehicle staging location, the catch basin serving the staging area will be covered with a
temporary mat to restrict liquids from passing through the cover and into the storm water.
