-2- <br /> the first being a corten rigid span bridge in <br /> 4111 the price range of $12 , 000 - $14 ,000 per <br /> bridge . The second option was to work with <br /> the Twin City Tree Trust in constructing pole <br /> bridges in the amount of $4 ,000 - $6 ,000 . <br /> Staff indicated that the major problem with <br /> the corten bridges was the need for extensive <br /> footings and possibly piling which could be <br /> extremely expensive from an installation <br /> perspective . After reviewing the facts as <br /> presented , the Commission directed staff to <br /> go with the less expensive bridges to be <br /> constructed with the Twin City Tree Trust , <br /> with the additional dollars used for possible <br /> park projects. <br /> Staff indicated that there were four options <br /> for additional park construction projects <br /> which were as follows : <br /> 1 . Completing the second trail loop at a <br /> distance of approximately 2 ,600 linear <br /> feet. <br /> 2 . Installing four lit horseshoe courts. <br /> 3 . Purchasing additional site amenities, <br /> 1111 i .e . benches , trash recepticles and <br /> drinking fountain . <br /> 4. Security lighting by the baseball back- <br /> stop, parking lot and tennis court area. <br /> 5 . Construction of two bird observation <br /> towers. <br /> The Commission directed staff to develop <br /> additional research on each of the items so a <br /> formal recommendation can be made at the May <br /> Commission meeting . Following the review of <br /> additional projects , it was the general con- <br /> census of the Commission to proceed with <br /> other projects and to spend the dollars at <br /> Greenfield Park rather than return the grant <br /> monies to the State . <br /> Staff also indicated that formal approval had <br /> been granted from the Rice Creek Watershed <br /> District pending a hold harmless agreement <br /> from the City Attorney and that approval <br /> would have to be granted for the construction <br /> of two bridges which staff is in the process <br /> 1111 of securing . <br />
