<br />CONCLUSIONS <br />The theoretical foundation of site stormwater controls remains essentially the same as that of the original <br />Parkdale CUP, with the majority of the proposed changes referencing the expansion of permitted mining <br />areas and elongation of mining durations. Neither the sand and gravel pit nor the granite quarry propose <br />' the construction of any features or structures that will result in any sizeable increase in runoff from any <br />of the drainage basins identified within this narrative or corresponding Drainage Plan. To the contrary, <br />it is expected that the stripping and stockpiling of topsoil and overburden within the limits of disturbance <br />' will typically act to expose more permeable soils in the underlying strata, or provide for localized <br />detention, thereby reducing the expected overland runoff. At a minimum, the detention derived from the <br />internally directed drainage in both facilities will act to attenuate flood peaks, thereby regulating the <br />potential degredational impacts from these flow contributions, as experienced at points downstream. <br />1 <br /> <br />1 <br />u <br /> <br /> <br />11 <br /> <br /> <br /> <br /> <br />I Parkdale Quarry Drainage Report I Fremont County File No. CUP 07-003 <br />
