Hailey Manor Page 2 July 1, 2003 City of Lino Lakes, Minnesota Lots 3, 4, and 5, Block 1 of Mar Don Acres traditionally have drained to the landlocked low area in Lots 5, 6, and 7, Block 1. The proposed drainage computations do not appear to take into account Lots 3, 4, and 5, Block 1 developing. 4. City rate control requirements are not being met on the 2, 10, and 100 -year storms. 5. Approval from the Rice Creek Watershed District will be required. 6. The proposed drainage and utility easement shown on the utility plan and preliminary plat shall be expanded to cover the entire detention area in the center of the property. Standard lot perimeter easements shall be provided as shown on the preliminary plat. 7. The overflow for the detention basin connects with a City storm sewer catch basin located in Arlo Lane. This system eventually discharges to a 15 -inch diameter pipe at a grade of 0.3%. It is recommended that the capacity of this pipe to adequately accommodate the added pond overflow in addition to its existing flows be evaluated further. General Street and General Utility Comments Arlo Lane was constructed recently with concrete curb and gutter, bituminous surfacing, and utilities (sanitary sewer, storm sewer, and waterrnain). The Preliminary Utility Plan shows sanitary sewer and water services extending to lots 1-6, but does not identify the services as existing or proposed. The services must be labeled accordingly. The developer shall be responsible for any and all repairs to Arlo Lane that may be caused as a result of said development, including new concrete curb and gutter, aggregate and bituminous base, and bituminous surfacing as may be needed. 2. Lois Lane currently exists as an older bituminous street with no curb and gutter (bituminous curbing), and no existing utilities. The extension of sanitary sewer and water from their existing termination points on Lois Lane at the east lirnit of the site is proposed. Sanitary sewer and water services should therefore be extended to each lot (Lots 7-12) from the newly constructed mains. Extension of sanitary sewer and water services to the two proposed lots (Lots 1 and 2, Block 2) at the southwest corner of Country Lane and Lois Lane should also be provided and shown. The proposed watermain connection point on Lois Lane currently exists as a dead end main, and will be extended even further in length as a dead end. We are evaluating the system at this location to verify that existing pressures and flow rates at this location are adequate. 4. As a result of the utility main construction, the developer shall restore Lois Lane by complete reconstruction with concrete curb and gutter and new bituminous surfacing (i.e., the street shall be reconstructed to City of Lino Lakes standards). Said reconstruction shall be identified and provided on the plans. • 5. Concrete curb and gutter shall be identified as D412.
