A Traffic Control Plan is missing from the submittal. Please include measures for both the work within Dayton Street as well as the alley, and include notification measures for Fire, Aid, Police, and Trash haulers for if work requires closing of the alley. This is a requirement for issuance of the associated Right-of-Way Construction Permit. 2.1 A Haul Route Plan is missing from the plan set. The Haul Route may be overlain over the Vicinity Plan in your next submittal. 2.2 Staging / Laydown / Mobilization / Erosion Control. Please include these items in your civils.

A Separate Fire Connection Permit is required to be applied for and reviewed in conjunction with the civil drawings per the comments of the acting Fire Marshall. 4. A cost estimate is required for all on- and offsite work. The inspection fee will be based on 2.2% of 120% of all improvements, and the required bond will be based on 120% of the approved estimate for the offsite work. Please keep the on- and offsite work separate on the estimate. 5. We are unable to find the private easement for the storm line exiting the detention system and connecting to the city storm on Dayton.

Since the parking stalls will be enclosed, the existing catch basin shall have its lid changed to solid, and runoff from the interior parking shall be directed to a new, separate catch basin containing an oil-water separator, and from there routed to the sanitary sewer system. Revise the drawings accordingly, and include appropriate details for the catch basin and the separator. 7. Show how the roof drains will connect to the detention system. 8. Show existing sanitary sewer line from building to main. 9. Show existing water service and service line size from meter to building. Linda MacMurphy, the Water Quality Technician, notes in her comments dated 4/29/08: “Must show on plans premise isolation in hot box by meter just north of sidewalk, with a reduced pressure backflow prevention assembly.” 10. Please show grading calculations on the plan set, and how the figures were arrived at. Given the geotech’s report of the depths of loose soil onsite, it seems some overexcavation will be required to reach substantially dense soils. 11. Please provide a detail for the trash enclosure. A handout for requirements may by found at: http://www.ci.edmonds.wa.us/Public_Handouts/Engineering/E37-Garbage_Recycle_Collection_Enclosure_Access_Policy.pdf 12. Overlay sight triangles at the parking exit showing that a motorist exiting the garage has an unobstructed 80’ view of the alley. 13. Pave or overlay the full width of the alley from east to west property line. Please show this requirement on the civils. DATE E-MAILED 5/22/200 8 PAGE(s) 2 of 2
