Exhibit B- Site Description <br /> a. Please see attached custom soils report and the vegetation classification exhibit. <br /> b. Man-made structures less than 200 ft from affected area: <br /> • Fence along east side of the south haul road (please refer to exhibit B) owned <br /> by the City of Grand Junction Municipal Cemetery. <br /> • Headstones (please refer to exhibit B) owned by the City of Grand Junction <br /> Municipal Cemetery. <br /> c. Water will not be used with this application. This application is for reclamation only. <br /> The existing drainage will remain. It presently bisects the site running from north east <br /> to south west. The existing wetlands areas will remain. They are located along the <br /> south side of the site and along the existing drainage. A Stormwater Management <br /> Plan was recently approved by the City that called for a stormwater quality pond. The <br /> stormwater quality pond was built per the City of Grand Junction's SWMM <br /> requirements and engineered to meet their standards for WQCV. <br /> The layout of the proposed project area includes the installation of berms and <br /> associated stormwater ponds that are created as a result of the berms. Berm <br /> installation will separate the project area into several sub-basins which are all tributary <br /> to the Unnamed Creek. An analysis summary of the proposed drainage sub-basins for <br /> this project is shown in Table 1. for a graphical representation of the proposed sub- <br /> basins with respect to the project area. <br /> Sub-basins PR-02 and PR-03 represent the areas that will drain to the proposed <br /> berms. These areas are used as the basis for SWMM calculations pertaining to water <br /> quality requirements for each pond. There are no permanent impermeable surfaces <br /> installed as part of this project. However, the percent imperviousness of the project <br /> area will increase due to the proposed activities. Percent imperviousness of sub-basin <br /> PR-02 and PR-03 will increase from 5% (existing conditions) to 20% (proposed <br /> conditions) due to expected graveling and surface hardening in the project area. <br /> Sub- SCS Proposed Sub-Basin Peak <br /> Sub- Basin Curve Runoff Rates (cfs) <br /> Basin Area Number <br /> ID 100- <br /> (acres) (CN) 2-Year 10-Year Year <br /> PR-01 13.62 79.0 0.74 1.18 8.72 <br /> PR-02 10.06 89.0 0.54 0.87 12.07 <br /> PR-03 9.19 89.0 0.50 0.80 12.72 <br /> PR-04 18.29 79.0 0.99 1.58 10.35 <br />
