Memo to the Mayor and City Council/P96-13 Page 2 November 26, 1996 • size in the southeast corner. This parcel also has a single family home on the property which has access onto Proctor Road. The property has similar natural characteristics as the southern half of Lafayette Woods immediately to the west. A majority of the property is open with no natural vegetation. However, the north 280 feet of the property is wooded with a mixture of oaks and other mature hardwoods. Along the southern portion adjacent to the wetland complex there is a mixture of poplar trees and red twig dogwoods along with other vegetation commonly found along a wetland complex. Attached is a letter from Tim Edgeton of the County Tree Board explaining that the northern portion of the property had an oak wilt infection site, approximately at the intersection of Rush Street and 194th Avenue. Apparently, this has been controlled in the past by the County Tree Board; however, the area is considered high-risk for additional oak wilt. The property does have varying topography which naturally rises from north to south. Overall, the property has a grade change from a low point on the south of 914 up towards the north to a high point of 980, a grade change of 66 feet. Streets The street layout has taken into consideration an existing extension from Lafayette Woods to the north. A planned extension from Lafayette Woods to the west and the current alignment of Highland Road as it intersects with Proctor have also been tied together. The connection of Lafayette Woods from north and Highland Road is a link that was talked about with the Lafayette Woods development. This stretch of roadway will be developed with a sidewalk along one side of the road from Lafayette Woods to Proctor Avenue and ultimately, along Highland over to Jackson. There are four cul- de-sacs proposed as part of the plat, none of which exceed the maximum length of 700 feet for a cul-de-sac. It should be noted that the plat has no provisions for extending any streets in a northeast direction towards the two undeveloped parcels which will be "sandwiched" between Lafayette Woods and the proposed Cherrywood Hills. As mentioned in the City Engineer's memo, the proposed Highland Road extending west of Proctor should be redesigned to include a tangent section of approximately 100 feet. This will allow for a true perpendicular intersection which is the proper geometrics for this type of intersection. • The plat includes four "T" intersections. Ideally, these intersections should occur right at a property line so that headlights of oncoming vehicles shine through the yards and not into the house.
