SAFEngineering <br />Site and Athletic Facility Engineering, PLLC <br />4521 Bridge Court <br />Shoreview, MN 55126 <br />GREENFIELD PARK: There are two tennis courts and two partial basketball courts at this <br />location. The tennis courts and basketball court have not been maintained within the past 15 <br />years. The fence system is in fair condition and the area has a lighting system. There are <br />numerous structural cracks, approximately 2,000 lineal feet, in the pavement surface. These <br />are the type of cracks that will allow water into the subgrade and cause continued growth and <br />expansion. There are also a moderate amount of fissure cracks. These are the type of cracks <br />that are only within the color coat system and upper 1/8” to 1/4” of the bituminous surface. The <br />color coat surface is in fair to poor condition with a very faded surface. There are indications of <br />water ponding on the surface. <br /> <br />RECOMMENDATIONS AND COST ESTIMATES <br /> <br />GROVELAND PARK: <br /> <br />Option One: Seal all cracks with a colorized elastomeric sealant <br />designed for tennis courts. This method of rehabilitation will provide a <br />service life of 1 to 3 years. $6,000 <br /> <br />Option Two: Fill all cracks with a mixture of Portland cement, <br />silica sand and polymers. Color coat the entire area and restripe. <br />This method of rehabilitation will provide a service life of 3 to 5 years. $20,000 <br /> <br />Option Three: Fill all cracks with a mixture of Portland cement, <br />silica sand and polymers. Cover the cracks with “Armor” crack repair <br />system. Color coat the entire area and restripe. This method <br />of rehabilitation will provide a service life of 5 to 8 years. $70,000 <br /> <br />Option Four: Remove the existing bituminous pavement, net posts and <br />net tie-downs. Reshape and compact the existing base aggregate. <br />Pave the area with 3” new bituminous in two lifts. Install new net posts <br />and tie-downs with air driven posts to eliminate the concrete footings. <br />Sawcut control joints in the new pavement between the courts and along <br />the net line to allow for expansion and contraction. Color coat the entire <br />area and restripe. This method of rehabilitation will provide a service life <br />of 15 to 20 years with routine maintenance and color coating. $100,000 <br /> <br />Option Five: Completely reconstruct the tennis courts and basketball court. <br />Remove all of the existing materials. Construct a new pavement section <br />consisting of 3’ of bituminous in two lifts over 6’ of class five base aggregate. <br />Install a new fence system within a concrete maintenance strip. Install new <br />net posts and tie-downs with air driven posts. Sawcut control joints in <br />the new pavement between the courts and along the net line to allow for <br />expansion and contraction. Color coat the entire area and restripe. <br />This method of rehabilitation will provide a service life of 20 to 25 years <br />with routine maintenance and color coating. $130,000 <br /> <br />GREENFIELD PARK: <br />
