Planning Commission January 31, 2013 Page Two 2. We are currently exploring the options for looping of the watermain through the development to Arcade Street as part of this development or to Westwind Drive or Labore Road as part of the future ghost plat development. Based on the outcome of that review a connection to the Arcade Street watermain may be added to the plans. Landscaping Plan 1. Due to the grading necessary it is not feasible to save trees within the interior of the property, but perimeter trees are being saved to the extent possible. 2. The Developer is showing tree replacement at the City required rate of 30 caliper inches per acre of disturbance. This equates to 195 caliper inches of tree replacement based on the 6.5 acres of disturbance. The City Planner will likely comment on the landscaping plan and its adequacy. Drainage Calculations 1. Drainage calculations have been completed for the development as part of the storm sewer design to document existing drainage patterns and rates have been maintained along with the required treatment. The current property drains to the west and northwest into the existing ditch on the west side of the property. This ditch system was improved by a joint City and Ramsey Washington Metro Watershed District project in 1993 based on a design by the Watershed's Engineer and serves a large area to the north of the development. We have submitted the drainage calculations to the Watershed for review and approval for both permitting requirements and review of the larger ditch system.
