Case File: 06-03 Page 7 Water Municipal water will be provided to the site via. two connections from the west, one at Liberty Heights Drive, and another at 189th Avenue. Water will be circulated and looped throughout the site, providing secondary sources of water for emergency and water quality needs. Future connection points are provided to the south (Bur:h~mJn street). The City Engineer will need to approve the location of all hydrant locations as part of the formal approval of the construction documents; this may result in the provision of additional :fire hydrants. Sanit:a.1;y Sewer. Sanitary sewer will gravity flow throughout the project, to a new lift station in the northwest comer of Liberty Heights Drive and Bur:nl!1"HI11 Street. This lift station will direct flow to the Riverpark development, where it enters the municipal system.. A portion of the sanitary sewer will route through the school/ city property. Storm Sewer. Storm water will be collected via. a series of on street catch basins, and rear yard catch basins and route to one of several treatment ponds scattered throughout the project, before discharging ultimately in the wetland. The City Engineer has developed comments regarding the utility and grading plans. These comments are not expected to drastically alter the layout of the neighborhood. These comments should be addressed as part of the final plat and construction drawing development of the plat. Landscaping The developer has proposed a landscaping plan, with includes boulevard and buffer plantings: Street trees. Staff has encouraged the developer to plant street trees, in part to better enhance the neighborhood, define the streets cape, and calm traffic. As part of the PUD negotiation, staff had recommended 1 tree per 40 lineal feet of street frontage, to be planted by the developer at a given date. The plan does show boulevard trees, though not at the ratio suggested by staff. Staff feels that the plan as presented meets the goals stated above. Staff supports the Boulevard tree planting plan. The boulevard tree planting does not satisfy the individual yard trees planted by the property owners. Buffer trees. The developer also proposes buffer plantings along the ea.stem edge of County Highway 40 and a portion of County 33. This buffer helps define the "private" portions of the property from the public streets. The buffer plantings include a variety of over story (Maple, Oak, Linden), omamental (Birch, Crabapple, etc), evergreen (pine, spruce, etc) and large shrubs. The buffer area. along County 33 (Viking Boulevard) includes a 1-2 foot berm above the surface of the road. Along County 40, south of the park, the berm is more pronounced. A fence is also proposed along County Highway 40, though not detailed. This fence should be detailed prior to final plat approval. The ratio of plantings proposed along Co 40 are recommended by staff: lover story, 1 omamental, 1.5 evergreen, and 3 shrubs per 40 feet of buffer frontage. Staff suggests that the buffer planting be extended along the entire frontage of County Highways 33. North of the school/ city property, a new buffer is not recommended, as existing trees provide the separate of space. If, during construction it is agreed that the trees should be removed, a new buffer should be provided. Signage No entrance or neighborhood identification signa.ge has been identified.
