The trail would remain in use during construction, and the activities associated with it would not be As a requirement the easement, approximately 12 trees along th.e HVT would need to or dead. Currently, there is dense undergrowth along the trail made up sumac, be removed as they are currently obstructions within the RPZ. The majority the trees that are to be removed are elm and black cherry. Many the trees are in poor health required. The 15-foot height clearance is necessary to provide adequate clearance for height restriction will still allow maintenance vehicles to access the path as needed. trail exceeding more than ten feet in height would be highly unlikely. Therefore, the any obstructions such as trees, utility poles, etc. In order to meet FAA requirements for approaching aircraft. The easement would allow the airport to control the height any structure or other obstruction within the easement. It is assumed that vehicles on the the RPZ, an aviation easement over the trail with a clearance 15 feet would be RPZ s function is to enhance the protection people and property on the ground, and Currently, the H\/T is located within the airport s Runway Protection Zone (RPZ).

14 RECEIVED United States 27 June 2011 Department Agriculture JUN Jason Whitten - Animal and Plant Health DLZ V Inspection Service 1425 Keystone Ave. Lansing, MI Wildlife Services 2803 Jolly Road Suite 100 Okemos, Ml Dear Mr. Whitten, I have read your proposal for the creation 0.8 acres Oakland/Southwest Airport and fer the following comments regarding the potential increase in wildlife hazards to aviation. In this situation, risk is a combination the feature to wildlife as a source food or cover and its proximity to the airfield. The creation this wetland would result from the on-site mitigation an existing 0.53 acres an airport improvement project. The proposed mitigation site is currently maintained as mowed once the conversion to wetland occurs, the site would revert to a shrub-scrub type wetland with no standing water. Shrub-scrub wetland already surrounds the proposed site. This proposed wetland is also located directly south the runway and was previously the crosswind runway. Making an evaluation is difficult in this case because there is no way to evaluate the degree that birds and mammals will utilize this newly created wetland. But given the fact that this wetland is small, contains no standing water and will be similar to the surrounding habitat, it is my opinion that this wetland would present only a negligible increase in wildlife activity at 0/SWA. There should be a reasonable effort to observe this new wetland for bird (0/SWA) attractiveness wetland as part new wetland at turf grass and and mammal activity regularly throughout the year. significantly, there should be a commitment by the airport to take mitigating measures such as harassment or control the hazardous species. Thank you for allowing us the opportunity to review and comment on your wetland mitigation plans. Feel free to contact me questions. If wildlife hazards rise if you have any Sincerely, zr 2cL Tim Wilson Wildlife Biologist APHIS Safeguarding Amencan Agnculture Federal APHIS is an agency USDAs Marketing and Regulatory Programs Relay Service (Voice)TTYIASCI I/Spanish An flnnnrt,,nit, Prn,,idnr on,4 Fnni,n,r
