Attachment 18 - ENG COMPLIANCE MEMO-PLN2020-0054Date: To: From: Subject: MEMORANDUM February 11, 2021 Kernen Lien, Environmental Programs Manager Jeanie McConnell, Engineering Program Manager PLN2020-0054 — Design Review for Tree Cutting Point Edwards — 93 Pine Street Engineering has reviewed the subject application and found the information provided is consistent with Title 18 Edmonds Community Development Code & Engineering standards. As discussed in the application documents, a stormwater pond exists on the north side of the property. In addition, there are both private and public utilities located within the vicinity of proposed work. The City's GIS web map can be referred to for approximate location of utilities, but as a precautionary measure utility locates shall be called for prior to any tree removal. The City's GIS map can be found at www.maps.edmondswa.gov. GIS snap shots of the various utility systems at the site have been provided at the end of this memo. In addition to protecting utilities while work is being performed, all work shall be done in a manner that minimizes slope disturbance as well as disturbance to the stormwater pond. Page 10 of the Point Edwards Assocation Permit III -A Permit Application: Design Review for Vegetation Modifications on a Geologically Sensitive Critical Slope, dated December 16, 2020, provides the that following methods will be used: "All work will be done by hand to protect the integrity of the slope. There will not be any grading or changes to the slope. There will not be any modification to the slope contour, nor will any heavy equipment or machinery ever be used to move or compact soil. The three project Phases will be completed by people using small handheld, gas -powered tools such as chainsaws and/or trimmers, or using handheld digging tools like shovels and wheelbarrows. If a wood -chipper is used to create mulch, it will never enter the slope or be positioned on bare soil. Instead, the chipper would be parked on the existing access road to the pond; with debris manually carried off the slope to be processed on the road. Only material blocking replanting will be removed from the slope to turn into mulch, and it will in turn be used to mulch new plants".
