ll <br />Zoning File #2183 <br />October 17,19i6 <br />Page 2 <br />minimum 20’ setback. Staff recommends that the protected wetland within the northern portions of <br />Lot 2 be staked in the field to ensure a minimum 2u setback from proposed fill (review Exhibit G). <br />Septic test sites on Lots 2, 3 and alternate on 4 must be staked prior to any earth movement. <br />Staff found the wetland located in the northwest comer of the property to be severely degenerated <br />and would not classify the wetland as a Type 7. Creation of open water area within the low retention <br />area would create an upgraded wetland along with benefit to varied wildlife. <br />The W’etland located within the street yard is of more concern for staff. The wetland appears to be <br />a true Type 7 wetland. Review Exhibit J, the DNR information lists several species of wildlife that <br />benefit from this type of wetland. John Smylhe, an aquatic specialist at Bonestroo. was asked to <br />review the proposal. He advised that if this is a true Type 7 wetland and shows no sign of <br />degeneration that these are rare and should be protected. The creation of an open w ater area w ould <br />not raise the value of this wetland. <br />Upon your inspection note the several mature trees within the wetland. Based on the design specs <br />provided in the alteration plan. Exhibit G, it would appear that the majority of trees would be <br />eliminated. Staff has discussed this concern with Mark Gronberg and he noted that it is applicant's <br />intention to attempt to save the trees with the creation of an irregular pond for the purpose of <br />encouraging other forms of wildlife. The creation of open water ponds seems to be the preference <br />of many Orono land owners as we have an abundance of open water ponds at 4’ depths similar to <br />applicant's proposal. <br />Staff recommends that John Smythe of Bonestroo inspect this specific portion of the Type 7 wetland <br />to determine the degree of degeneration if any. Based on his findings, staff w ill either recommend <br />saving the Type 7 as it exists today or allow the dredging of the open water area. Staff will present <br />Smyth's findings at your meeting on the 21st. <br />Options of Action <br />To approve as proposed or amended (pending final report of John Smythe). Any recommendation <br />of approval must include the following conditions: <br />1.Prior to the placement of spoils on Lots 2 and 3, the Type 2 wetlands w ithin Lots 2 and 3 are <br />to be staked in the field to ensure 20' setback is maintained. <br />2. Septic sites on Lots 2, 3 and alternate on 4 are to be fenced off prior to any earth movement. <br />3. All disturbed areas shall be protected with suitable erosion control until ground cover is <br />restored.
