Redevelopment Karch 4, 1993 Likewise, Deveral catch basins are i.n place in the north when related to City right of way areas. Additional basins will ba added. A critical location is in the north along the curb line which captures a substantial portion of parking lot run off. Presently, one basin is proposed, however, staff questions if another should be added. Drainage calculations should be submitted for verification purposeD. This catch basin empties into the north wetland which is the present condition. Drainage in the northwest is piped to the water quality pond and ultimately to the wetland. The drainage system for the building should feed into the new water quality system so that roof run off can also be treated. Drainage patterns associated with the 7-Hi center remain unchanged. This means building and parking run off will continue to flow over land. Riley/Puragory Creek Watershed District approval is required. City services are available to the site. presently, a sanitary sewer main extends adjacent to the north edge of 7-Hi center. This main will be relocated around the new Rainbow store rather. than building over the main. A new easement must be grantRd. An 8" water service will be extended to Rainbow Foods directly from the 12ft water main within the Highway 101 right of way. An 8" water main will also be extended onto the site from Highway 7 and will service both bank and new center. This main will be looped within the site. Sanitary sewer will be extended from the on site main Btub ended at the west end of the Wendy's drive aisle. The southern landscape plan combi.nes natural vegetation near wetland boundaries with more formal plantings within the developed site. Quaking aspen and white spruce are proposed along the western edge which will provide a natural buffer between the site and the sedimentation pond. Staff is recommending the addition of another species of deciduouB tree such as red or sugar maple so that the aBpen ia not the only species introduced. CUrrently, vegetation exist9 adjacent to the gravel parking lot of the auto dealer. It would appear from the grading plan that much of this will be preserved. Efforts to keep vegetation should occur, however, many of the deciduous trQes are dead or dying. This area should be cleared of debris and new plantings be in9ta1led along the wetland fringe. In the north, the landscape plan is similar in that more informal plantings occur in the west and formal occurring on the eastern portion of the site. Greenspire Linden is the deciduous tree used in all landscape areas. Additional varieties should be explored. Some islands illustrate shrubbery only, while the area north of the liquor store contains no plantings. Trees, whether deciduous or ornamental, should be contained witldn every landacape island. Quaking A9pen and colorado Spruce are found adjacent to the water quality pond. Staff is concerned that soils in the area may not be conducive to plant growth for some species proposed and the applicant should diacuBs this further with the City ForeBtsr. During the neighborhood meeting, concerns were expressed by nearby residents about off site views. Because the residents are generally at a higher elevation, the site viewD from the western residential area are fairly clear, particularly in the winter. Fo~ this reaaon, the color of the back of the building was changed to 8 darker earth tone. Aleo due to these comments, additional landscaping was added from that initially proposed. In total, 58 coniferous and nine deciduous trees were added to a9siBt in screening the 7-Hi bu1.ldi1\9 and associated activity. OVerall, etaff believes that the number of 10
