29 This plan shall provide a demonstration of how the goals and standards of § 25- 29.3 through § 25-29.5 are being met. The focus of this plan shall be to describe how the site is being developed to meet the objective of controlling groundwater recharge, stormwater quality and stormwater quantity problems at the source by land management and source controls whenever possible. 5. Stormwater Management Facilities Map The following information, illustrated on a map of the same scale as the topographic base map, shall be included: i. Total area to be disturbed, paved or built upon, proposed surface contours, land area to be occupied by the stormwater management facilities and the type of vegetation thereon, and details of the proposed plan to control and dispose of stormwater. ii. Details of all stormwater management facility designs, during and after construction, including discharge provisions, discharge capacity for each outlet at different levels of detention and emergency spillway provisions with maximum discharge capacity of each spillway. 6. Calculations i. Comprehensive hydrologic and hydraulic design calculations for the pre- development and post-development conditions for the design storms specified in § 25-29.4 of this ordinance. ii. When the proposed stormwater management control measures depend on the hydrologic properties of soils or require certain separation from the seasonal high-water table, then a soils report shall be submitted. The soils report shall be based on onsite boring logs or soil pit profiles. The number and location of required soil borings or soil pits shall be determined based on what is needed to determine the suitability and distribution of soils present at the location of the control measure. 7. Maintenance and Repair Plan The design and planning of the stormwater management facility shall meet the maintenance requirements of § 25-29.10. 8.
