Final Site Plan Review: NAUParking Lot Expansion May 8, 2009 Page 2 of 4 implementing new topsoil requirement for all new construction, and would I would highly encourage the use of -this new material in all irrigated areas for water conservation. • The sidewalk along 145' Avenue should be extended all the way to the intersection of Rhinestone Street. • Provide the City with a copy of your Watershed permit. Landscaping: One (1) tree per every ten new parking stalls is required either within the parking area or directly adjacent to the stalls and there are sixty-one (61) new stalls proposed. The landscaping plan, dated April 29, 2009, includes sixteen (16) trees and eight (8) shrubs. Six (6) of the trees are within the parking area or directly adjacent to the stalls. Staff has the following comments on the landscaping plan prepared by Hakanson Anderson Assoc., Inc.: • Due to the presence of Emerald Ash Borer (EAB) one (1) mile east of Minnesota and a quarantine that is now in effect in Huston County,. MN, a non-ash species must be used in the boulevard plantings along 145' Ave NW. • Due to the low branching of the blue spruces, they should be planted far enough back from- the curb to avoid conflicts with vehicles parking and/or maneuvering within the parking area. • The following information should be included in the planting details and the plan should also include a deciduous tree planting detail: o Planting depth such that root collar/flare is. at finished grade. o Remove twine, wiring, ropes and burlap from top and sides of root ball. o Only prune out dead or damaged branches. All necessary pruning cuts shall be made just outside of branch collar area. o Remove all tags and labels. o Wood chip mulch to a depth of 4 inches, tapering to a depth of 2-3 inches at perimeter; shallow mulch near trunk (1 inch max, do not pile against trunk). • Size of shrubs at time of plantings shall be at least twenty-four (24) inches in height. • All unimproved areas of the site must be sodded. Any alternative to sod will require City. Council's approval Please revise and resubmit plans accordingly. It should also be noted that additionally landscaping will be required at such time that a building is proposed for this site. Irrigation: All new landscaping shall be irrigated by an in-ground .system. Irrigation metering and backflow devices shall be approved as part of the Utility Plan, and installed accordingly. Irrigation rain sensors shall be installed and appropriately placed throughout the site. Tree Preservation: The site is devoid of any significant tree cover and therefore, no tree preservation plan is necessary. Access: The office building and parking lot propose to gain access from an existing ingress/egress on Sunwood Drive as well as 145 Avenue on the adjacent parcel occupied by NAU Insurance. A cross access agreement will need to be secured if the two parking lots are to be connected as indicated on the. site plan. Also, the existing access onto Sunwood Drive will need to upgraded to City standards, and include a concrete apron to the back of the sidewalk. In addition, one additional access is being proposed on the subject property on 145'i' Avenue. No new accesses will be allowed on Sunwood Drive; now or in the future. -217-
