Orchard Hill of Orono - Project Narrative 06/27/2017 Stormwater Management. Stormwater management for the development is being designed consistent with the City's Local Surface Water Management Plan (SWMP), the City's Stormwater Overlay District, and the Construction Site Runoff Control Ordinance requirements. The official map of the City of Orono Stormwater Quality Districts classifies the subject property as a Tier 1 area due to its proximity to the Long Lake Creek tributary. As such, it is subject to a limitation of not greater than 25 percent hard surfacing. The project proposal is well under this threshold. In addition, the grading and stormwater plans for the site are subject to rigorous regulations including a stormwater pollution prevention plan (SWPPP) incorporating best management practices (BMP's) as prescribed by the MPCA. The grading and drainage plan includes the use of multi -cell treatment principles and methods designed for both rate and nutrient control including phosphorous and total suspended solids reduction. The management plan also uses storm sewer to convey runoff to ponding areas prior to collection in abutting wetlands. The proposed detention ponds will be included in the common area maintenance declarations under the HOA covenants. Tree Preservation. Tree preservation will be a priority. A comprehensive tree inventory will be completed as part of the preliminary plat and PUD submittal phase. As with most development, tree loss will be inevitable; however, the developer is committed to aggressive measures to save significant tree cover and individual trees where possible. Trees located within the No -Mow zone will be preserved and protected with securely anchored, heavy-duty fencing during construction. The developer is also committed to preserving individual trees around building pads on each lot where feasible. Construction fencing will be used to protect trees them from root compaction and damage from construction equipment. A professional certified arborist will be employed to help identify trees which can and should be saved and to prescribe the best management practices to ensure their protection and health going forward. Tree Replacement. In addition to professional landscape treatments on each individual lot, the developer is committed to designing and providing a common area landscape which compliments the premier quality of the proposed neighborhood. Consistent with the project's namesake, Orchard Hill of Orono, we are planning for a leafy and verdant streetscape. To that end, we are proposing that the boulevard and other common areas be planted with a variety of oak, maple, linden, evergreens and other flowering ornamental trees. A generous budget of is proposed for common area tree planting. All common areas will be placed under the ownership and management of the future home owner's association. Cnnclusinn In summary, we are very excited for the opportunity to present this proposal to the City of Orono and we hope that City officials will give this project a satisfactory concept review based on its many fine attributes. We believe the project's high-quality, and medium density, single-family orientation, provides the best practical design solution for this unique property. The increase in allowable density that is being requested through the proposed comprehensive plan and zoning district classification amendments is a component that the Metropolitan Council and the City of
