Re: Approval of the City of Tigard Local Wetlands Inventory and Assessment 's$
Dear Mr.Roberts: i
�i
I am pleased to notify you that the Division of State Lands has approved your Local Wetlands
Inventory(LWI)and assessment. We appreciate your working closely with our staff and the
wetland consultant to ensure that the inventory meets state LWI standards(OAR 141-86-180 to t `-,
4 240)and the city's needs.
Division approval does not guarantee that the wetlands depicted on the maps are the only a„
regulated wetlands in the inventory area,and there may be upland areas within the mapped '
.wetlands:However,after a thorough review,my staff is pleased with the quality of the LWI and
.comfortable that it incorporates most wetlands and waterways. Exact wetland boundaries have
not been staked and surveyed,.and there are inherent limitations in mapping accuracy::For these ,
'reasons,the Division advises who proposes land alteration within 50 feet ofamapped �r .,,
wetland toobtain awetland boundary delineation by a qualified consultant and submit it to the
Division for approval prior to the land alteration. +
Approval by the Division means that the LWI becomes part of the Statewide Wetlandsi(.
Inventory:-:Also,the LWI must now be used in lieu of the National Wetlands Inventoryfor the '..,,
:Wetland Land Use Notification Process(ORS 227.350):.We are pleased that the City of Tigard
has made a thorough wetlands inventory and wetland planning high priority,and that we were
able to help provide EPA pass-through funding for this important work. j
't Respectfully, '.
