Ms. Katie Larsen <br />04/10/2024 <br />Page 6 <br />Lino Lake Tech Center Engineering Review <br />(WSB 3/6/2024) Submitted <br /> <br />2. We recommend that the City Deputy Director of Public Safety-Fire Division review the <br />proposed plan when submitted <br />(Amcon 11/13/2023) Understood. <br />(WSB 11/29/2023) To be reviewed at the time of full submittal <br />(WSB 3/6/2024) Fire official to review updated submittal including fire coverage <br />shown with hoses <br /> <br />3. (WSB 3/6/2024) Show gate valve installed with wet tap <br />(Elan 3/26/2024) Gate valve has been shown on plan. <br />(WSB 4/5/2024) Complete <br /> <br />4. (WSB 3/6/2024) 6" PE pipe proposed for directionally drilled water service across <br />Lake Drive/ right of way. <br />a. The City requires PVC C900 in the right of way <br />(Elan 3/26/2024) PE was chosen to allow for directional drilling. Directional drilling C- <br />900 is not feasible. The cost of jack/boring a casing pipe is prohibitive and open <br />cutting the busy road would be a mistake. We request permission for the alternative <br />material which has been used in similar situations for decades. <br />(WSB 4/5/2024) Call out on plans as HDPE SDR 18 <br /> <br /> <br />5. (WSB 3/6/2024) Clarify whether this is the 'relocated' hydrant from the Removals <br />sheet <br />a. Fire Official to review whether a new hydrant is required <br />i. If acceptable call out as install salvaged hydrant (assembly) <br />(Elan 3/26/2024) The hydrant that exists on site is less than 5 years old. <br />There is no reason why, if carefully removed, that it should not be <br />suitable for reuse. <br />(WSB 4/5/2024) Call out on existing conditions as ‘salvage existing <br />hydrant’; Call out as ‘install salvaged hydrant and furnish and install 6” <br />gate valve’ on utility plan. <br /> <br /> <br />6. (WSB 3/6/2024) Existing 6" hydrant valve to remain is located in a proposed private <br />parking space <br />a. Fire Official to review and confirm access to gate valve <br />b. Consider cutting back and installing a new shutoff valve to the north and the <br />existing hydrant assembly (including valve) would be installed by the building <br />(Elan 3/26/2024) The valve serves no real purpose other than allowing the existing <br />line to remain active during construction and avoiding the need for this project’s <br />contractor to pressure test the existing system along with the new. The valve’s <br />location is immaterial. <br />(WSB 4/5/2024) Complete <br /> <br />7. (WSB 4/5/2024) Verify minimum separation (18”) between sanitary sewer main and <br />proposed looping water service. Offset water service under sanitary sewer as <br />required to maintain minimum depth. <br /> <br />8. (WSB 4/5/2024) Clarify that the connection to the existing 12” watermain should not <br />shut down the active line. Tapping sleeve will need to meet City requirements. <br /> <br />119
