Christine Mattson From: Adam Edwards Sent: Tuesday, November 21, 2017 12:35 PM To: Christine Mattson Subject: RE: 1080 Tonkawa Drive/2017-01466 Chris, To address neighbors' concerns I would adjust my comments thusly: I've reviewed the subject plan and offer the following comments: 1. The Grading Plan should be revised to indicate perimeter erosion control measures(silt fence, bio logs,etc.) down gradient from proposed work. Measures must be installed by the Contractor and inspected by the City prior to any work. Contractor must provide a minimum 24 hour notice prior to inspection. 2. Wetlands are depicted on the landscape plan but no the survey/grading plan. 3. A stormwater basin (sub surface) is depicted on the landscaping plan but not the survey/grading plan. This should be shown on the grading plan. 4. Surface runoff must not be directed across property lines. The applicant should consider connecting the drainage way on the northeast side of the property with the drainage system depicted on Sheet L2.00 of the architectural plans in order to ensure water kept off the neighboring property.
