2) Width of Emergency Spillway Design: 12 feet. Measured: 12.2 feet. <br />3) Depth of Eme~enc~Spillway Design: 1.55 feet. Measured: 1.60 feet. The spillway <br />showed no evidence of flow or any signs of erosion or other instability. <br />4) Width of top of Dam Design: 10 ft. Measured: 10.2 ft - 10.6 feet. <br />5) Princ~al Spillway Design: 4.0" pipe placed in compacted embankment. Measured: <br />4" steel pipe placed in compacted embankment. Extensions on this pipe were added to <br />both sides so that the embankment could be widened. Some black plastic hose was also <br />present near the spillway at the time of the inspection but was not functional. The <br />principal spillway pipe was completely free of debris and was functional during the site <br />visit. <br />6) Dam Slopes Design: 2.SH:1.OV. Measured: Outslope 2.SH:1.OV with large rock <br />(>24" diameter) placed near gulch. Inslope: 2.SH:1.OV. The slopes were solid in all <br />locations and showed no evidence of erosion or gullying of any kind. <br />7) Pond Denth Design: 15,0 ft. Measured: 15.9 ft. Water level was approximately 0.0' <br />feet at the time of the inspection. <br />8) Rip Rap Lining in Emergency S illway Design: 12" thickness of 10" to 12" rip rap, <br />durable rock. Measured: 12" thickness of 10" to 12" rip rap, durable rock. <br />9) Sediment Storage Volume: Design: 0.22 acre-feet. Measured: 0.4 acre-feet. <br />10) Storm Detention Volume: Design: 4.08 acre-feet. Measured: 4.1 acre-feet t 4%. <br />11) Rip rap at Discharge of Principal Spillway Design 8" diameter durable rock. <br />Measured: as designed. <br />12) Sloe Stability There was no evidence of seepage anywhere along the outside of <br />the embankment or the principal spillway pipe although the pond did contain water. <br />There was also no evidence of cracking, bulging, slipping or other signs of slope <br />instability. Vegetation was excellent on the top of dam and all sidelsopes. Previous <br />compaction tests done on the dam material were within specificakions. There was no <br />evidence of freeze thaw action at any point along the embankment. <br />As a professional engineer experienced in embankment slope stability design, <br />construction and maintenance, I am confident that the dam meets the long term slope <br />safety factor of 1.3. In fact, past experience indicates that the slope safety factor is <br />most likely above 2.0. It is stable for the following reasons: <br />
