Adelaide Landing Preliminary Plat/PUD – Narrative <br />4 <br /> <br />WETLANDS <br />A wetland delineation has been completed and approved for the site. Of the 58 acres of existing <br />wetlands, only 1.34 acres are impacted by development. The impacts are generally due to street <br />alignments and connections. In all, 98 percent of the wetlands are preserved creating vista views and <br />spaces for trails to meander through; a true amenity that will be further enhanced with site <br />development. <br /> <br />Impacted wetlands will be mitigated by purchasing credits from an approved wetland bank. <br /> <br />The existing ditch through the site will be enhanced to become a site amenity, similar to a small creek <br />or brook. It will be cleaned out and include a trail that runs parallel to it. Pockets of landscaping will <br />be evident along the path. <br /> <br />PONDING <br />Due to the high groundwater levels, the site needs to be raised. As a result, deep ponds will be <br />created to not only generate material to raise the building sites, but to also manage storm water. <br />Additionally, the ponds will be used for irrigation to meet water reuse and infiltration requirements. <br /> <br />Approval is being requested to use the adjacent city-owned Outlot A, Country Ponds for ponding. <br />Ponding will enhance the outlot’s existing condition as well as create a more seamless transition <br />between the properties. In exchange, a trail will be constructed between the pond and wetland which <br />will be part of the neighborhood’s public trail system. As shown in the Typical Pond Cross Section <br />of the Preliminary Plat, a 15’ buffer is proposed off the adjacent property lines with a 10’ bench from <br />HWL. Overstory trees are disbursed along the pond to create a break from the existing homes <br />without impeding water & wetland views. <br /> <br />The floodplain boundary is depicted on the Preliminary Plat as agreed upon between the engineers <br />for both City & Developer. Ultimately, the floodplain elevations will need FEMA approval by way <br />of a LOMR. This will occur once grading activities are completed and elevations can be certified. <br /> <br />PARKS & TRAILS <br />In all, the site proposes a combined area in excess of 100 acres for park, open space, ponding, wetland <br />buffer and wooded area. The extensive trail system not only leads to the centrally located park, but <br />also meanders around wetlands and ponds, providing a greater connection with the natural <br />environment. Boardwalks further serve to protect the existing wetlands. <br /> <br />Approval is being requesting for the adjacent city-owned outlot to be incorporated into the <br />engineered site design. The outlot will be used for ponding, which will also enhance the existing <br />wetland. In exchange, a trail will meander through the outlot between the pond and wetland to offer <br />greater connectivity to the adjacent public park. <br /> <br />It is understood that park dedication for new development can be achieved in one of two ways: land <br />dedication (10% of net developable area) or a fee in lieu of land ($2,400 per unit). With a net <br />developable area of 146.2 acres, 14.6 acres of park land dedication is required. Per the attached Park <br />Exhibit, the total outlot area dedicated for park or public use is 35 acres. This encompasses wetland,
