This letier addressa the City's rccommendation end concems regarding the approval of the as-builts and release of 50'/e of the wetland bank credits associated with the Nerbeck Wetland bank. Const�uction of the Nazbeck Wetland bank appeers to have procceded on a smootha track than tMe Swanson project. I am pleased with the vast majority of the improvements mede to the site(including the park improvements). There are a few concerns that we would appreciate a response on prior to your cectifying release of the credits. Some of these issuea were raised and answered or committed to at the Oversight Committee meeting. Our concems are as follows: I. Any photos used in future monitoring documents should be dated. We will note in our copies that all of the photos in the As-Built Report were taken in January 1999. 2. The Airport committed to supplementing the plantings in the southwest buffer area as recommended by the Corp. We concur in that requirement. 3. Water quality monitoring of nutrients shall include appropriete phosphorous and nitrogen compounds. 4. The Airport or their contractor is committed to watering of new plantings as required by conditions on the site. 5. Additionat vegetation should bc installed along Na�-!:eck Creek as it exits the site. This wuld be pert of the Sabey stormwater pipe project or if that does not progress in a timely manner, the vegetation should be installed this winter. 6. Liz Greenhagen or I should be notified in advance of the expected date when the "leaky berm"will be activated. The City would appreciate the opportunity to monitor that activity.
