�_. c. There is so:ne concern that thc depth of the building foundadons may cause drawdown of the water table near the wedands, especially if pumps may be useci to draw water away from the 8 foundations. the following mformadons should be submitted to the City to help address this concern: * T6ie depth of the footing drains with respect to the wedands; * The soil types and permeabilities between the wedands and the buildings; * The dischazge location of the fofoting drains and the proposed methods of dealing with collected water; * The elevation of the ground water table in the vicinity of the building and near the wetland. d. A buffer a minimum of 50 feet wide is required around the two wedancis on the site. A 10 foot construction se:back is requued frorn the edge of the buffer. A 10 foot setback is also required from the wetpond to allow main�enance of the buildings and fire access, unless othenvise approved by the Fire Marshal. (SEPA Water, and Public Services and Utilities Polic�es) e, Prior to isssuance of any permits, a plan must be approved which shows the existing landscaping in buffer areas, the buffer areas that will need enhancement planting, and a planhng plan for any buffer disturbed during construction (for example those azeas ad�acent to proposed driveways and walkways). (SEPA Water, Plant and Animal Policies) h. Prior to issuance of any permits, a monitoring plan must be reviewed and approved by the Planning Department. The plan must provide for monitoring the wedanJ and buffer vegetation and the weUand hydrology for a minimum of three years. The monitoring plan must include a contmgency plan which discusses potential measures to take if it is determined that the conshUction of the project has impacted the wedand hydrology. The monitoring plan must include photo documentaiton. pn assurance device for the monitoring and contingency plan must be submitted to the planning I)epartment prior to the issuance of occupancy permits. The amount of the assurance device shall be for 110% of the cost of the monitoring and the plantings. (SEPA Water, Plant and Animal, and Public Services and Utilities Policies) Prior to issuance of occupancy permits, tt►e apQlicant's biologist must submit a letter stating that the wetpond and buffer planhngs have been mstalled per approved plans. The City will not be responsible for maintenance of the wetpond azea. (SEPA Water, Pland and Animal, and Public Services and Ulilities Policies) Per City policies, due to the proximiry of the site to environmentally sensitive areas, seasonal limitations will be placed on land alteration activities. Land alteration activities are defined in the �i��'� Ihden �nd Gort_�c�on SL� a ic d �pecifications as Clearing, Grupping, Excavation, Filling, Grading, and Stockpiling. Determination of the exact seasonal limitation period requires site specific mformation generally not available until the project design stage. However, preliminary analys�s using the information avazlable at thts time indicateci that land alteration acbvities on the project site will be restricted to the period between April 1 and October 1.
