Ms. Katie Larsen <br />8/6/2025 <br />Page 3 <br />Clearwater Commons – Engineering Review <br />a. Verify adequate fire flows for 8” non-looped design <br />BPA (7/7/2025) See Fire Flow Test Review letter from Nova Fire Protection <br />enclosed. Available flow and pressure is sufficient for proposed development. <br />WSB (8/6/2025) Provide turning movement diagram for emergency access to <br />the hydrants and sites <br /> <br />2. Call out all utility crossings <br />a. Provide minimum 18" separation between water and sewer <br />b. Insulate when separation between water and storm sewer is less than 36" <br />BPA (7/7/2025) Utility crossing invert and top elevations are now called out. <br />WSB (8/6/2025) Complete <br /> <br />3. Provide utility service(s) for future commercial lots to the north <br />a. Consider extending watermain along access road north and looping to <br />Michaud Way to improve resiliency and limit impacts to the roadway with <br />possible future utility installations. <br />BPA (7/7/2025) Utility services are now provided to the 2 lots on the north <br />side of the east-west drive aisle. It is infeasible to connect the water main to <br />the north. Future lots on the north will be able to extend that watermain as <br />needed. <br />WSB (8/6/2025) Complete <br /> <br />4. Note existing 8" gate valve shown on watermain stub in record plans <br />a. Test existing gate valve (2015) and <br />if keeping <br />i. Connect to existing 8" DIP watermain; delete proposed 8" gate valve <br />BPA (7/7/2025) The existing gate valve is proposed to be kept. A <br />note has been added to field test existing gate valve. <br />WSB (8/6/2025) Complete <br /> <br />if not keeping <br />ii. Remove existing 8" DIP pipe back to and including existing gate <br />valve; Connect to existing 8" DIP watermain with new 8" gate valve <br /> <br />5. Install 8" gate valve to isolate Lot 1/Chipotle service <br />BPA (7/7/2025) Gate valve has been added <br />WSB (8/6/2025) Complete <br /> <br />6. Call out phase limits for Lot 2 water service <br />BPA (7/7/2025) These limits are now more clearly called out. <br />WSB (8/6/2025) Complete <br /> <br /> <br />• Sanitary Sewer <br /> <br />The existing 8” sanitary sewer stub at the intersection with 21st Avenue will be utilized and <br />extended to the eastern limits of the development to serve the 3 commercial lots to the <br />south and potentially one or more of the future commercial lots to the north. <br /> <br />Comments: <br />1. Match existing sanitary sewer pipe slope (0.40% - field verify) from connection <br />through to first structure <br />BPA (7/7/2025) The sanitary sewer is now matching the existing slope <br />Page 160 of 168
