Development Issues Meeting Process
The purpose of a Development Issues Meeting is to give an applicant the opportunity to discuss
his/her development proposal with the development review staff of the City. The discussion can
be general or specific, depending on the details provided with the application. A Development
Issues Meeting provides information to an applicant related to the current development
conditions and standards of the City. The Development Issues Meeting is not a land use decision
and does not confer any development rights, establish any conditions, or bind the applicant or
the City to any course of action. The meeting conveys the status of known development
opportunities and constraints. The status may change over time as development conditions or
standards change.
1. Applicant Submits a Development Issues Meeting Application
• The application must conform to the Development Issues Meeting Submittal
Requirements Checklist on page 3 of this application packet.
• Development issues meetings are conducted every Thursday.
• We strive to conduct the development issues meetings within three to four weeks of
receiving the application.
• The applicant's proposal is circulated to the relevant staff in preparation for the
meeting.
2. Applicant and the City Conduct the Development Issues Meeting
• The applicant and any design team should attend the development issues meeting.
• The meeting is scheduled for one hour.
• Staff attending the meeting will be prepared to discuss the issues raised in the
submittal by the applicant. Other issues raised during the meeting may also be
discussed.
• The meeting is informal and the City will issue no staff report.

DEVELOPMENT ISSUES MEETING APPLICATION
Date: October 14`, 2020
Project: Thurston Water Treatment Plant Siting
Relevant Excerpts from McKenzie River Water Source Study —July 2016
Following are some excerpts from the McKenzie River Water Source Studywritten by V urraysmith
in 2016. These excerpts discuss the plans for the member filtration watertreatment facility at 954
661" Street.
Water Treatment Facility
Excerpt from page 5-6, Membrane Filtration Overview
Given the raw water quality, the primary focus for treatment of the McKenzie River source is
removal of particulates and microorganisms. Low-pressure membranes — using either
microfiltration (VF) or ultrafiltration (UF) —are particularly well suited for achieving such
treatment objectives. Membranes remove particles using size exclusion based on the small and
uniform pore size of the membrane material. Both OF and VF provide an absolute barrier to
protozoa such as Cryptosporidium and Giardia. The primary difference between VF and OF is
the size of the membrane pores and thus the size of particles removed. OF membranes can
achieve some virus removal whereas VF membranes typically cannot.
The fact that membranes provide an absolute barrier to protozoa is one of the key features that
recommend them for this application. Another advantage is that filtered water quality is far less
dependent upon achieving precise and optimized process chemistry with membranes than with
conventional treatment.
Excerpt from page 5-9, Treatment Building
Figure 5-2 shows a conceptual layout for a building to house the complete membrane system as
well as most ancillary systems. The membrane module footprint is based on the larger open
platform design. The building includes space for:
• Pre -filtration strainers
• A pipe galleryto connect the influent and effluent from all the membrane module racks
• An electrical room
20-2963 Page 1 of 4 Thurston WTP Siting
October 2020 Springfield Utility Board
• A mechanical room
• A lavatory
• A laboratory
• Acontrol room
• A meeting room
The building also includes the following spaces for chemical storage with secondary containment:
• Sodium hypochlorite, for disinfection and for chemical cleaning of the membranes
• Sodium hydroxide, for pH adjustment of finished water and for chemical cleaning of the
membranes
• Acoagulant, which may not be required due to the low TOC values for the raw water
• An acid, typically citric acid, for chemical cleaning of the membranes
• A chemical to dechlorinate the waste streams generated by the weekly and monthly
hypochlorite cleanings
• The CIP tank and the CIP skid with pumps and controls for cycling the cleaning chemicals
between the tank and the membrane modules.
The finished water pump station is attached to the eastern end of the treatment building. The
finished water pumps and the motor controls for those pumps will be located in separate rooms
within this eastern extension of the treatment building.
Excerpt from page 5-11, Storm Water Design
Storm water runoff from roof structures can be conveyed directly to an existing storm sewer that
runs along the west side of the treatment plant site. All runoff from the paved areas will be
conveyed to the water quality Swale shown along the southwest of the property in Figure 5-3.
Decant water from the backwash basins, if not recycled to the head of the plant, could also be
conveyed to the Swale to ensure that the water discharged meets requirements for total
suspended solids and residual chlorine. The Swale shown in Figure 5-3 has been sized to also serve
as a reservoir overflow detention pond, capable of storing approximately 150,000 gallons of
overflow with six inches of freeboard.
Excerpt from page 5-15, Land Use
The proposed site for the new Thurston WTP is located adjacent to a school. It is bordered to the
south and east by existing residential urban development and to the north by land zoned Exclusive

Farm Use. In order to minimize impacts to the surrounding community, including visual, air and
noise impacts, the treatment technology should:
Allow for efficient use ofthe site to allow for incorporation ofvisual screening, landscaping
and other elements to mitigate the long-term impacts of siting of a municipal facility with
regular staff presence, truck deliveries of chemicals and equipment, and operating
mechanical equipment in close proximityto residences.
Easily provide for management of potential air quality impacts (odors) resulting directly or
indirectly from the treatment process, including chemical storage and use, interactions
between free water surfaces and the atmosphere, etc.
Minimize noise impacts associated with the operation of mechanical equipment, staff
activities including maintenance and cleaning of facilities, etc.

Questions
1. The property is zoned Low Density Residential (LDR) and "public utility facilities" are
allowed used in this zoning designation. "Low Impact° public utility facilities are permitted
uses in LDR-zoned areas. However, "High Impact° public utility facilities require "Special
Development Standards° that are subject to special location or sighting standards. Would
the water treatment plant be considered a low impact or high impact development?
Are there any concerns related to having treatment chemicals close to a school and
residential neighborhood?
3. Is the facility on Metro Plan's Public Facilities and Services Plan?
