We will consider the use of the narrower pier foundation at Airport Road and 100th Street SW. Do you have any available As-Builts from the construction of this-3.6"water main? I have not yet received the GIS data from Brent. Also, I double checked the records we received from both Everett and Snohomish County and cannot find record maps of the traffic signal fiber optic lines along Airport Road. Can you and Euneka help me track this down? Maintenance of the detention pipe at Airport Road and Kasch Park Road will be considered. I will need to discuss this issue with the Swift team to determine if further relocation is preferred. Thank you, Matt :Matthew Scarsella I E.I.T.

Below are our comments on the proposed relocations. Water main @ Airport Rd. and 100th St.SW (UT32): because this is a 16" DI main that was recently installed we would prefer this to stay in place.Therefore,our preferred solution would be to modify the footings as brought up in the meeting to avoid adding additional stress to the main.We also have an air valve located on this line that falls near or at the north side of the structure. It does not look like this is currently mapped,so this should be added to determine whether the air valve needs to be modified. SA:96 ' a LcoCa. � Dl PLa,..i.s— Drainage detention pipe @ Airport Rd.and Kasch Park Rd (UT33):This relocation is fine, however the City will need to clean this detention pipe on an average of every 5 years.To do so we will have to park a vactor truck south of the shelter and place a traffic control taper that will block off the station for a few hours to a day.The only way to avoid doing so would to have the detention relocated south a couple hundred feet (to place the station outside of the traffic taper).
