The grading plans are dated 9-25-09 and the landscaping pians are dated 9-21-09. We have the following comments with regards to engineering matters: • The proposed retaining wall is shown as 4.0 feet in height. If field changes increase the height, engineering design and details must be submitted for review and approval. • An unclassified wetland has been identified along the creek that will trigger Orono's wetland buffer ordinance and must be shown on the plans. This will require a wetland delination. • The wetland classification must be determined to properly apply the bufFer ordinance. The applicant must use the Minnesota Routine Assessment Method (MnRAM)to classify the wetland. • The landscaping plan indicates that the existing buckthorn hedge is to remain. • The landscaping plan shows a bridge over the creek and the site plans do not. If a bridge is to be installed, detailed engineering design information must be submitted for review. The bridge work may also require permits from USCAE, DNR, and MCWD. We recommend that the applicant provide evidence that these permits have been obtained or that they are not needed. • This project will disturb more than 100 CY of material. Sediment and erosion control information meeting the requirements of Orono's City Code 79-7(c)(2) must be submitted. The minimum $2000 sediment and erosion control financial security should be required of the applicant for this permit.
