We have the following comments with regards to engineering <br /> matters: <br /> • There is a Manage 2 wetland on the property that may receive drainage from the <br /> proposed addition. Wetland buffers may be required by ciry ordinance for this project; <br /> however there is not enough information available to fully evaluate the plans against the <br /> buffer ordinance. <br /> • Additional plan information should be submitted to address the following triggering <br /> criteria established in Section 78-1601. A wetland buffer will need to be established if all <br /> of the following three conditions exist: <br /> o The portion of the property disturbed by construction or land alteration activity <br /> drains to the wetland; and <br /> o The amount of grading exceeds 50 cubic yards or the construction activity <br /> involves the disturbance of more than 5,000 square feet of area; and <br /> o The redevelopment activity results in a net increase in the square footage of <br /> impervious surfaces that drain to the wetland, or results in the relocation of <br /> impervious surfaces closer to the wetland, or results in changes to drainage <br /> patterns (slopes, meander patterns, etc) that the city engineer determines will <br /> increase the velocity or rate of runoff to the wetland. <br /> • This project will disturb �ess than 100 CY of material. Sediment and erosion control <br /> information meeting the requirements of Orono's City Code 79-7(c)(1) must be <br /> submitted. The minimum $2000 sediment and erosion control financial security should <br /> be required of the owner for this permit. <br />
