Stormwater Development Task Sample Clauses

Stormwater Development Task. The stormwater development task has had a change in scope from our original SOW proposal as a result of our analysis of the original permit documents. Our previous proposal was based on the assumption: “No design changes are expected. If design changes are required based on permit extension requests, ▇▇▇▇▇ ▇▇▇▇▇▇▇ will notify DSWM and we will discuss how to proceed”. Based on the original permit that included the MSE berm, we have significantly changed the site grading, conveyance, and we have the opportunity to increase the southeast pond size. Based on discussions with DSWM, we have been directed to pursue the increased pond size, develop a site specific stormwater model (using ICPR), design for the regrading, revise the construction drawings, and submit a Florida Department of Environmental Protection (FDEP) permit determination request. The FDEP permit determination request described the changes to the permit based on the following: ▪ The impervious area is not changing and is the area of the landfill and the associated roads and infrastructure. ▪ The treatment volume is not changing and is based on the impervious area. ▪ Stormwater basin delineation and pond areas are not changing. ▪ The landfill stormwater collection system is not changing, this is a system of down-comers routed to a network of concrete-lined ditches. As part of the FDEP permit determination request we contended that the changes to the Cell 1A area should not require a permit modification, however, FDEP has requested a minor permit modification that will include the ICPR modelling, application form, and site plan. We are preparing the minor modification permit application. This application should not affect the current schedule. Removal of the MSE berm alters the slopes of the conveyance and the travel time of the stormwater. However, the post-development run-off is reduced from the pre-development conditions. The revised stormwater development tasks are summarized below: ▪ Permit extension requests and notifications (in progress). ▪ Stormwater modeling calculations, design, and permitting (in progress). ▪ Prepare Bid Documents, including design drawings, technical specifications, and opinion of probable construction costs (in progress). ▪ Perform engineering services during construction (future effort). Because of the changes to the stormwater scope of work, we have revised the landfill development tasks to include these tasks in the second phase of this project (see Section 2 for m...
