lots. Out lot W is 9.03 acres in area that is owned and utilized by the City of Waukee for regional
storm water detention. Out lot A is 0.35 acres in area that the applicant is acquiring from the City to
utilize in conjunction with the development of Lot 1. Out lot B is 0.35 acres in area that the applicant
will deed to the City to Make up for the acquisition of out lot A.
SE Esker Ridge Drive and SE Glacier Trail are the two streets that have been identified on the

Glacier Trail will be major collector streets measuring 37 feet wide with a 70 foot right of way.
Several easements are proposed within the plat based upon the location of proposed utilities. In
addition to easements for utilities, the preliminary plat identifies prospered ingress/egress easements to
provide access to the proposed lots. A 25 foot landscape buffer easement will be required along the
ease plat boundary to provide screening from the adjacent properties a 25 foot landscape buffer is also
provided on the south line of out lot Z.
Utilities will be provided to lot 1 as part of plat improvements. Sanitary sewer will be extended from
Grand Prairie Parkway along SE Esker Ridge Drive to the intersection with SE Glacier Trail. Water

was constructed by the City of Waukee located in Out lot W of this Plat.
Commissioner Broderick questioned what the out lot W Pond would service and Mr.

questioned if there would be any storm water flowing south, and Mr. Deets advised
that in terms of detention it will all go north to the Pond.
Commissioner Hoifeldt questioned if SE Esker Ridge Drive would extend to Grand
Prairie Parkway. Mr. Deets advised that it will extend across the parcel to Grand
Prairie Parkway as development continues and with the help of a Rise Fund Grant.
Commissioner Streit asked for clarification on the out lot B and out lot A exchange.
Mr. Deets advised that it was discovered during the final plat that a deeper lot may be
needed for a proposed building so there was an exchange of even sized out lots
negating the need for a bid process.
