The three cities involved with the major upgrading (Spring Park, Mound, Orono) have worked closely with the County on the planning of this upgrading for over three years. The final plan as presented to the Council and the City were once again reapproved approximately two months ago. Upon review by the Orono staff, it was determined that a land use application would have to be filed by the County in order to cover the encroachment of the wetland and floodplain area and the filling adjacent to the shoreline at the western edge adjacent to the Spring Park border. Wetland/Floodplain Encroachment - Review Exhibits H, I, and J Both the DNR and MCWD have required permit reviews for the encroachment of the wetland/floodplain areas. Review exhibit D. The DNR waived the permit review ana issued a permit for the project finding a lack of another feasible and practical alternative based on the public need rule outweighing the no build alternative. Review Cook's letter (exhibit F) and exhibits H and I. Total area encroachment of the filling of the wetland/floodplain area totals .05 acres. Cook advises that the excavation of the ditch on the north side of County Road 15 will replace the storage capacity of the wetland/floodplain areas filled with the project. Part of this project involves replacement of the culvert under County Road 15 increased from 24" to 30". The actual control of the drainage from the wetland is at the 24" culvert at Casco Point Road on the south side of 15 and further east. The major drainageway to Carmens Bay travels from that wetland area under County Road 15 and then eastward on
