DISCUSSION OF THE REACHES By dividing the drainage-way into reaches, each reach can be discussed individually as follm,s:" REACH 1 This length of channel has remained nearl.y in the historical condition. During regular maintenance of the Camp -George He8t grounds, the area has been graded, mowed, and cleaned to facilitate. the passage of storm runoff. The only obstrucU_on to runoff is the cha.in link fence along the West property line. It is considered in all likelihood that during a major storm this fence would be "ashed Ollt. REACH 2 The e..'Cisting 48" CSP culvert located unde.r the dri.veway a.t Noss Street was installed by the County. During a recent storm the driveway was not washed out even though the drive"ay \ms overtopped by runoff. This testi- fies to the fact that if the culvert is correctly installed, repetiti.ve and costly maintenancE~ can be mi.nimized. The channel above Noss Street has been used as a dump ir. the past years and much of the debris along the banks is floatable. If a large enough storm \{ere to oceur, much of this d3bri.s would float dOlm to the culvert and plug it. Any designed system can potentially becornE~ inoperative due to debris plugging, and damage.s can and cIa occur. REACH 3 The 36" CSP culvert located under Nile St:reet has b,een installed tn best fit the existing conditions at the culver~ locatio~. Just above the culvert on the North Eide of the channel sevl~ral residents have constructed garages or sheds ClOSE to the channel. This condition .Limits thE! cha.nneling Hhich could be accomplished above the c.ulvert to improve its operation. The channel Hest of Nile Street ",as excavated by the County to alleviate local flooding problelt.s. Some of the existing fences and out bllildi.ngs are nQ1;" at a point of sliding into the channE~l caused by the continual erosion 6
