Applied <br /> Buffer Width is 40' (25% of 160' =40' which is greater than 25') � <br /> • New house could be located 40' from Preserve wetland in property where the <br /> full 75' base buffer width could easily be met. Current Orono Code would <br /> require 50' buffer plus 20' setback. <br /> Ezample 3 for 6f.: <br /> • How does one determine the Applied Buffer Width under 6f. for a completely <br /> new home on an existing lot when there is no existing house being replaced? It <br /> would be 25�feet under MCWD code - 50' buffer plus 20' setback under Orono <br /> code. <br /> We went over these examples with MCWD staff. In general, MCWD buffer rules for single <br /> family homes are likely to result in lesser buffer widths than current Orono code would require. <br /> As noted above, MCWD staff is proposing a rule change within the next 2 months or so to have <br /> all single family residential buffers be 25 feet. We expressed a concern that we want to have a <br /> wetland setback that is at least equal to whatever buffer they would impose (if triggered) plus an <br /> additional mowable yard area of 10-20 feet. They suggested that we might want to establish a <br /> wetland setback of 35 feet,which would accomplish this. <br /> DRAFT Wetland & Buffer Management Strategy FOR DISCUSSION <br /> Based on the discussion above and with the intent to follow direction provided at the joint work <br /> session, staff would offer the following strategy for moving forward: <br /> 1) The City would continue to protect wetlands and will retain ordinances that protect <br /> wetlands per the Wetland Overlay District. MCWD will remain as LGU for WCA. <br /> 2) The City would defer the establishment and regulation of wetland buffers to the MCWD, <br /> since all wetlands in Orono are within the jurisdiction of MCWD. <br /> 3) The City would re-establish a wetland setback for structures from the delineated wetland <br /> boundary, regardless whether a buffer exists or is required. <br /> 4) In order to establish and administer a setback requirement, Orono must have the ability <br /> by ordinance to require wetland delineations on any property where wetland setbacks <br /> may be required. To reduce the delays and costs to applicants, staff will perform a Level <br /> 1 Delineation and only require a Leve12 delineation when it is critical to know the exact <br /> wetland boundary for setback measurement purposes, i.e. when it's not obvious that the <br /> project is meeting the required setback. Alternatively, we could establish a set distance <br /> from project to appazent wetland beyond which we would not do a Leve12 delineation. <br /> 5) Wetland setbacks would be required as follows, regardless whether or not a buffer has <br /> been or is being formally established by requirement of the MCWD, City of Orono, or <br /> other authoriTy: • <br />
