AGENDA ITEM 5A STAFF ORIGINATOR: Marty Asleson DATE: March 29, 2006 TOPIC: Legacy Town Homes /Legacy at Woods Edge BACKGROUND: Legacy Town Homes is located in the NE quadrant of the Legacy at Woods Edge Development site. See Attachment 1. Since the preliminary plan has been reviewed for Legacy of Woods Edge, input is now confined to site specifics for projects programmed within the Preliminary Plat approval. The landscape, lighting plan, and erosion plans are submitted as review items. Surface Water issues and general landscape issues have previously been brought to the Board. Landscape The proposed plant schedule is presented on sheet C5.0 (Attachment 4). Several changes should be made to the plant schedule. Recommend changing Sunburst Honeylocust to straight thornless Honeylocust. It is fairly well known that Honeylocust will develop nectria canker in artificially created urban micro - climates and Sunburst more so than thornless honeylocust. Sugar maples will not do well in the sandy soils of Woods Edge. Red or Sunburst maples should be substituted for the Sugar maples. Americanna /native (Redmond) Lindens should be substituted for the Cordata /non native (Greenspire) Lindens. European larch should be changed to the native Eastern Larch. Ponderosa pine should be changed to native White Pine or Red Pine. The area to the east of impervious areas and bordering the basin area (trail location area) should be planted with native Eastern Larch in the wet to mesic soils, and white oak with Red oak in the upland areas. This area including the pond areas to the North and South should be placed in a Conservation Easement with the City named as the easement holder. This area should be planted with a City native Seed mix. No top soil should brought in for native seed areas. Conservation easement areas should be protected from construction impacts such as compaction, debris and material stockpiling, and cement truck cleaning. Top soil note in the landscape plan. Should read "all areas disturbed by construction activities except for native specified seed areas should have 4 inches of loam top soil thourghly incorporated into the subsoil and seeded or sodded..." Again, where native plants are specified, no topsoil shall be specified. Raingarden and infiltration basins...should read "shall receive the City specified native seed mix."
