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.

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 20-2883 Page 2 of 4 Thurston wfP Siting October 2020 Springfield Utility Board 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. 20-2963 Page 3 of 4 Thurston wTP Siting oiztober 2020 Springfield Utility Board 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? 20-2963 Page 4 of 4 Thurston wfP Siting Oiztober 2020 Springfield Utility Board PLAN SCALE: 1'=20' FIGURE 5-2 McKenzie River Surface Water Source Development Preliminary Study Conceptual Layout for Membrane Filtration Building "**> October 2020 murraysmith 20-2863 � N.00I STORAGE COAGULANT STORAGEROOM MEETING aff y < MECH ROOM ELEC ROOM STRAINERS PHASE I PHASE 2 PHASE 3 PIPE GALLERY FINISHED WATER PUMPING ROOM AND SEPARATE RON FOR PUMP ELECTRICAL EQUIPMENT SKIDS MEMBRANE r1 PHASE I PHASE 2 PHASE 3 NOO STORAGE CITRIC ACID OECHLIXt CHEM CUP TANKS H d h SKID u PLAN SCALE: 1'=20' FIGURE 5-2 McKenzie River Surface Water Source Development Preliminary Study Conceptual Layout for Membrane Filtration Building "**> October 2020 murraysmith 20-2863 Fm I rc I I � I S' CONNECTION TO EXISTING 42"SD� I 600' �9' SETBACK - - TO ROA' (TYP) NOTE: 30% OF SITE TO BE IMPERVIOUS SURFACE.
