This is based on the vertical control system <br />being set and would be under the direction of the City Engineer. <br />A map showing the high water elevations of the critical ponds <br />would also be provided for the not to exceed cost of $1800.00. <br />The vertical control system is a tool which would be of great <br />value to the city and its residents and land owners for many <br />years to come. Both city officials and developers could use the <br />vertical control system in the development of the city. Having <br />bench marks available assures that elevations taken in the city <br />would all be based on the same datum. The useable life of a good <br />vertical control system is indefinite, but probably exceeds 50 <br />years with some checking and maintenance. <br /> <br />Sincerely, <br /> <br />HAKANSON ANDERSON ASSOCIATES, INC. <br /> <br />J s~~M.
