Matt Saam presented the staff report on this item. Commissioner Keefe asked about erosion
control and tree planting/removal as well as where on the plan the grading is actually going to
take place and how much material is going to be removed. Commissioner Tjornhom asked
Planning Commission Summary - August 17,2004
where the creek on the site started and if it would be protected from erosion, if there would be a
lot of trucks accessing the site, how long the grading operation would take, if there will be
wintertime operations and how the material would be compacted. Commissioner Papke asked
about how the site would be graded and whether or not there would be a mountain of fill sitting
on the site over the five years. He also questioned the reforestation and if there was a plan to
insure the survival of the seedlings. Commissioner Claybaugh asked if there was a monitoring
process in place for the seedlings and for clarification on the amount of material to be exported
and the phasing plan. Commissioner Keefe asked about environmental issues. Commissioner
Sacchet asked about environmental status of some original tree growth, the amount of trees being
cut, the creation of new bluffs, how the security amount was calculated, verification of the
number of trees recommended for replacement, if the proposal is consistent with the City's
Comprehensive Plan and if staff has seen any studies from the applicant regarding trees,
topography, bluffs, utility services, wetlands and storm water. Matt Saam and Kate Aanenson
responded to the Commissioners' questions. The applicant, Dan Herbst of The Pemtom
Company, addressed the Planning Commission and answered questions from the Commission.
After discussion, the following motion was made:
