The City of Meridian approved the Emerson Park Subdivision preliminary plat in December 2007 (PP-07-014). The project will be phased, and the current submittal reflects proposed Phase 1 improvements. Proiect Description Currently, there are two commercial operations on the site. Victory Greens operates a wholesale landscaping supply business on the majority of the site. The 2M Company operates an irrigation supply store on approximately 1 acre on the Victory Road frontage. Phase I of the project will focus on platting the lots along the Victory Road frontage. These lots are relatively large (1 acre, +/-) and some are already improved. Specific plans for development of these lots are contingent on the goals of future buyers; however, it is anticipated that development will generally follow the same plan as the existing 2M Company building. Storm Drainage — Existing Conditions Currently, there are two existing storm drain systems within Phase 1 of the site. A seepage bed system is used by the 2M Building for retention of all water generated by the impervious area of the 2M building and parking and storage lots. This system was reviewed and approved by City of Meridian through the Certificate of Zoning Compliance (CZC) permitting process in 2006. A second system consists of piping from Block 1, Lot 4 of Phase 1 and eventually outfalls north of the proposed Block 1, Lot 3. Storm drainage from Lot 4 is conveyed to an irrigation ditch and ultimately makes its way to the north end of the property. Drainage on other areas of the site primarily is achieved by infiltration. Storm Drainage — Proposed Phase 1 improvements are designed to handle storm drainage generated by South Holleran Place, a proposed public road. Storm drainage from individual lots will be retained on the lot and will be the responsibility of future owners. The proposed improvements reflect a temporary system to be abandoned upon completion of Phase 2 improvements. The ultimate storm drainage plan at build -out will include catch basins and piped storm drain system along South Holleran Place which will convey storm water to a future retention basin located at the north end of the property. To calculate peak discharge and peak runoff volume for phase 1 improvements, Thompson's Rules No. 1 and 2 were used. The road was divided into two drainage areas based on anticipated drainage from the crown of the road. The areas are indicated on the attached Drainage Site Plan. Emerson Park Subdivision — Phase I 2 Storm Drainage Report For Drainage Area #l, the peak discharge rate is 0.354 c.f.s. and the peak runoff volume is 1236 c.f. The volume will be retained in a V-ditch or borrow ditch located at the north side of the temporary turnaround. For Drainage Area #2, the peak discharge rate is 0.200 c.f.s. and the peak runoff volume is 700 c.f. The volume will be retained in a V-ditch or borrow ditch located at the south side of the temporary turnaround. Proposed Improvements — Soil Considerations A Geotechnical Engineering Report, dated August 24, 2006, prepared by Materials Testing and Inspection, describes soil conditions in the general area of Phase 1. A copy of the report has been included in the Appendix. Soils in the vicinity of TP-2 are the most likely to be encountered during construction of the retention V-ditches. Lean clay was encountered from 0 to 1.2 feet, followed by sandy silt from 1.2 to 3.6 feet. The sandy silt was expected to demonstrate infiltration rates of between 1 and 2 inches per hour, although the report notes that cementation may reduce this rate to near zero. It is expected that lean clay and organics near the surface of existing grade in the vicinity of the retention V-ditches will be removed during site clearing and grubbing. Earthwork and grading for the V-ditches is expected to expose the sandy silt. Given the anticipated infiltration rate, the V-ditches (with design depth of 20") will be fully drained within 24 hours of the design storm. However, given the nature of soils in the area, it is possible that a sand window or windows may be required in the V-ditches. Determination of the need for sand windows extending into the poorly graded sands or gravels (anticipated excavation depth = 5 to 9 feet) will be made in the field during construction by the Engineer. Conclusion The proposed storm drainage system for Phase 1 is intended to be a temporary system for use until permanent facilities are built during Phase 2. Storm drainage from individual lots in Phase 1 will be retained on site. Design and approval of these systems will take place as the lots are purchased and developed.
