Mallard Ponds Review Letter March 3, 2000 Page 2 of 4 named Argon Drive. The use of a private street is acceptable to the City, but the development agreement will require confirmation from the Developer that the homeowners covenants puts people on notice that the road will remain a private road and the responsibility of the homeowners association. The pavement width on the private street is proposed at 24 feet; parking must be restricted on at least one side of this private street to maintain adequate emergency vehicular access. Traffic Generation Analysis: A traffic analysis was commissioned by the City for this development. The analysis prepared by Mr. James Johnson of Hakanson Anderson Associates is appended to this review. The analysis shows relatively small traffic increases on local streets. Barium Street and 141'~ Avenue are estimated to have an increase of 12 trips per day. Argon Street and 142na Avenue show an increase of 103 trips per day; and Dysprosium Street north will show an increase of 98 trips per day. The traffic from this development would increase the traffic on Dysprosium north of 140t~ Lane by approximately 7.5% over 1999 volumes. There are no current traffic counts on Argon/142"a Avenue or Barium/I 41 ~ Avenue. Street Lights: The Developer should make arrangements with Connexus to install the street lights and send the utility bills to the homeowners as~'ociation. The City Engineer should be provided with a copy of the street light layout for incorporation into the City street light map. Grading and Drainage: A grading and drainage plan has been prepared by John Oliver & Associates dated February 14, 2000. This plan collects stormwater using two segments of storm pipe and transmits drainage into a three cell pond located between the townhouse units and the future apartment buildings. The stormwater detention pond outlets into the KANO pond which borders the parcel on the east. The City has an outlet from the KANO pond to the Rum River. This plan must be reviewed and permitted by the Lower Rum River Water Management Organization. Drainage calculations have been submitted and are under review. Off Street Parking Nodes: Per Staff's request, some additional parking nodes have been- identified on the Grading Plan and the Utility Plan. These 11 additional off-street parking spaces should also be incorporated onto the Preliminary Plat. Utility Plan and Drainage and Utility Easements: The standard 10 foot (5 foot on common property lines) drainage and utility easements have been provided. Per Staff's recommendation, the wetlands on the east boundary of the plat will be encumbered with a drainage and utility easement.
