Preliminary Plat and Site Plan Review: Ebony Woods August 31, 2006 ' Revised: September 22, 2006, December 20, 2006 Page 40[6 . 11. Traffic Generation Analysis: It is anticipated that this development will add approximately 60 trips per day to the existing traffic on Ebony Street which will subsequently utilize Riverdale Drive to obtain access to the regional road system. An analysis of the adequacy of the regional road system was conducted in Spring of 2004 in conjunction with the Rivenwick Village subdivision which consisted of 195 townhouse units. This analysis surveyed the conditions at four intersections which included: TH 10 I Ramsey Boulevard; ThlO / Feldspar St; TH 10 I Sunfish Lake Boulevard; Riverdale Dr I Feldspar St. This study showed that all of the above key intersections operated at an acceptable level of service with the exception of the THI0 I Sunfish Lake Boulevard which operates at a LOS E during the pm peak hour due to the high level of through traffic on Highway 10. It is important to note that this unacceptable level of service is not associated with the traffic being generated on Riverdale Drive, but is attributable to the traffic on Highway 10. The City is working with MnDOT to improve the capacity ofTH 10. The improvement to the Sunfish Lake intersection is currently scheduled for 2008. 12. -264- Utilities and Water Usage: The development will need to be served by municipal water and sanitary sewer. These services were installed in Ebony Street in 2005 and two services were stubbed out at the direction of the property owner who had anticipated two multifamily buildings being developed on the site. A utility plan dated August 3, 2006 has been submitted illustrating how the six twinhome units proposed would be served by the utility stubs provided. The connection proposed in this plan for the sanitary sewer services in this plan is generally acceptable, however staff would recommend that cleanout be. provided at each location were the flow would make a 90 degree bend or greater. This would require additional cleanouts for the building sewers servicing units 2, 4 and 5. With regard to the water services to these units, staff is recommending that a 4-inch ductile iron watermain be placed parallel to Ebony Street behind the east curb line to service all six units. This 4-inch main would be connected into the two 4-inch service stubs currently in place. All six units would be provided with a l-inch copper service stubbed into the 4-inch ductile iron watermain. The developer will need to pay sewer and water trunk charges on five units (a single trunk charge was assessed at the time tlle sewer and watermain was installed for the existing lot of record). In addition the developer shall be responsible for the costs associated with modifying the building services including restoration within the right of way of Ebony Street. " . 13. Sewer and Water Trunk Fees: As discussed in #12, sewer and water trunk charges are due on 5. of the 6 units. The ratein effect at the time of final plat approval will be charged; payment will be required before the plat is released for recording. 14. Park Dedication: The proposed plat will be forwarded to the Park Commission for a recommendation on park dedication. The City has the option for cash, land, or a combination of the two. Payment will be required before the plat is released for recording. 15. Trail Development Fees: The trail development fee in effect at the time of final plat approval will be charged; payment will be required before the plat is released for recording. .
