� 12-3561 12 July 2012 Page 3 of 5 Proposed Lot4 Lot 4 is also proposed as a corner lot with 2.02±dry acres; it will have 284 feet of frontage on CSAH 6 and over 250 feet on the new private road. The private road � should be considered the front for setback purposes and there should be no access directly on to CSAH 6. All required RR-1B setbacks can reasonably be met when this lot is redeveloped with a new home. Based on the existing topography,the developer should consider including a proposed grading plan for this lot if a walk-out home is to be proposed. Rural Oasis,Conservation Design &Woodland Impacts This project will trigger the need for the developer to conduct and submit a conservation design plan. The property has a an area of existing woods along CSAH 6 and along and a pine stand along the eastern property line, one 5+ acre wetland and an open view-shed over the wetlands from CSAH 6. The Rural Oasis Study and Conservation Design Master Planning process has been formulated to help determine on a case-by-case basis what natural values should be preserved. The purpose of Conservation Design is summarized in the Conservation Design ordinance as follows: The City of Orono as a result of the Rura/ 0asis Study conducted in 2005 finds that there is an intrinsic link between the natural systems and`the valued scenic character that exist throughout the community. The requirements of this conservation design ordinance are meant to preserve and enhance this ecological/aesthetic character by requiring: � (1J protection and enhancement of drainageways and water quality; (2J protection and enhancement of eco/ogical communities; � (3J reinforcement and establishment of ecological connections throughout the city; (4J augmentation and preservation of viewsheds including corridor enclosure and Buffering; (5J preservation and improvement of views;and (6J preservation or reinterpretation of local landmarks. Conservation Design is defined in the ordinance as follows: Conservation design means a two-phased approach to design and development that maintains or improves ecologica/ assets, provides infrastructure that works with the land, and incorporates people's instinctive desire to experience nature. Some conservation design strategies include: identifying and avoiding sensitive natural features, planning roads along contours, allowing lots to border natural open space, integrating ecological stormwater management, using smaller lots, and educating developer and buyers about the ecological values of the landscape. The first phase entails an inventory and analysis of the potential development site's natural features, existing land uses, and wetland delineation. The second phase entails analyzing the design implications of the findings from the initial phase, alternative stormwater design, and a conceptual design for road and lot layouts. Wetlands on Site and/or Impacted According to the submitted survey there is a 5+ acre Manage 1 wetland on the property requiring,a 35- ��foot native vegetated buffer and a 20-foot structural setback from the buffer. According to the survey, the wetland has been delineated; a copy of the wetland delineation report should be submitted to the City. The City will require a Flowage and Conservation Easement over all wetlands and buffers designated on the site.
