Becouse the proposed ecology blcc�: retaining wall iz more ihon 4-feel tall, ihe design ond pian lor ihe wail will need to be stamped & signed by a licensed professional engineer. Unfortunalely.

PGuI M`Kec •f�.'�-i s i-t1367 Comments from Mr. Sadler. t. Fxisting 10' sewer easement and elevated 8•inch sewer line—any retaining wall and (ill is requested to comply with Planning Dept.'s building setback requirements(rom an easement. In all cases the filt and wall must maintain a minimum of a 5-ft setback from the pipe or supports. At a site visit no stakes or boundaries oF the easement were (ound and it is unknown if the WSDO7 sound wall is on ihe property boundary or not. Staked boundaries of the easement and property lines would be useful (and I think should be done). L rlpplicant and Property Owner provides City a 15-ft drainage easement on the northem 15 (eet of property or where current drainage enters western edge oF properry and ilows eastward toward WSDOT wail and property. 3. Applicanl in�talls a 12-inch drein line from existing Type 2 CD on the north and westem ed�;e of property(northbound shoulder of eroadway). New drain line shall be centered in new drainage easement per tt2 and installed meeting City Development Standards. Applicant makes connection inro existing C4. Applicant submit plans of fill and drainage plan for approval prior to fill commencin�;or any drainage work. 4. At east terminus of drainline per N3, Applicant installs a Type 2 CB or equivalent(exterior drop manhole) to capture drainage. Pending City dreinage review—we do not have an issue if the site drainage is connected to this structure. 5. Applicant complete permit and coordination with WSDOT for connections and approval of drainage per �2,3, and 4 to enter and drain to WSDOT and submit to city prior to work. Thank you. i
