It seems you have <br />adequate irrigation but drainage is lacking which is the most important. The <br />existing conditions resulted in poor turf quality, inability to play due to unstable <br />wet conditions and higher maintenance costs. <br />3, <br />After reviewing the original construction design the drainage appears to be <br />limited, with having a sand base natural turf field it is imperative that a subsurface <br />drainage system be in place. Sand and peat hold water, that is good, but the <br />water has to be released to grow grass and allow high traffic sport activities. This <br />is a fixable issue without removing the existing field surface and reducing down <br />time. <br />We recommend installing a subsurface drainage system within the existing fields <br />connecting this system to the existing storm drains. <br />Sincerely, <br />Jeffery Hartman <br />8099 Bavaria Rd.
