• • • Grading will also be phased. The remaining pond excavation started as part of the Behms Century Farm 2nd project will be completed together with the ponds along the north edge of the Lino Air Park and the pond north of block 9. The central pond area will be constructed as part of the 3rd and 4`h Phases. TRAFFIC ANALYSIS SRF completed a traffic analysis on the project and the adjoining properties. The 250 units in the project together with the adjoining parcels located on the west side of the site were estimated to generate 1,952 trips per day with the A.M. peak hour generating 120 trips out and the P.M. peak hour generating 124 trips in. The report concluded that the existing road system will adequately handle this traffic. An important factor in the project design was to incorporate as many "traffic calming" features as possible. The curvilinear roads, offset intersections, private alleys and cul -de -sacs were the tools used to discourage through traffic. The Carl Street connection was designed as a "Tee" intersection to discourage traffic from going to the east from the project as requested by the existing Carl Street residents. Extensive street landscaping was used to further reduce vehicle speed. The following four road cross sections were used within the plan: 1. The Minor Collector road is a 66 foot right of way with 34 foot F -F paving. It is proposed to construct an 8 foot trail along the south side of the road. 2. Century Trail, which traverses most of the site has a 60 foot right of way with 32 foot F -F paving with a 6 foot concrete sidewalk along the south side from Sunset Road to Carl Street. The centerline of the paving has been offset to the north by 2 feet to provide additional boulevard space between the curb and the sidewalk. 3. The other public streets would have 60 feet of right of way and 32 feet F -F paving. 4. The attached town homes would have 16 to 18 foot wide private alleys for garage access, which would be owned and maintained by the home owners association. The front door of the attached town homes would be accessed from private sidewalks between the buildings. 5. Connections to the county road will be designed to meet Anoka County criteria and most likely have acceleration and deceleration lanes similar to those constrtucted along Lilac Street. At this time the county does not have any plans to upgrade Sunset Road. UTILITIES Trunk sanitary sewer and water main has been extended to the southwest portion of the site in Pinto Lane. The project will require installation of a lift station as part of the 1s` phase. This lift station will be designed to serve all of the property within the project and other adjacent parcels the as determined by City in its feasibility study. The feasibility study prepared as part of the Behms Century Farm project concluded that the trunk sanitary sewer and water main would serve all of the parcels within and adjacent to the project and lying south of Main Street. The water main will need to be looped. The feasibility study will determine the best location and the timing for the water main looping. Since the start of the Behms Century Farm project surface water management has been of utmost concern. The project contained a county ditch that effectively drained the entire area. The work to date has focused on creating significant enhancements to the drainage system and at the same time reduces the downstream impacts to the County Ditch system. The new system further reduces the long term maintenance needs of the county ditch system. The Century Farm North project continues this plan. Control manholes constructed as part of the 1s`, 2nd and 5th Additions of Behms Century Farm provide all of the rate control of the entire project. Numerous ponding areas provide for additional sediment control
