The project is one of the first projects in Italy seeking a LEED certification. It has been completed in 2006 and the team and the investor is trying to certify the building within the Core & shell system with the building\'s as-built-documentation, since it is not yet capable of fulfilling the minimum program requirements of the LEED EB O&M system. The remaining Prerequisites of C&S seem likely to be achievable. Regarding the Sustainable Sites Prerequisite 1 we approach you today and kindly ask for your Credit interpretation. Since the site was a brownfield inner-city re-development, all of the excavation had to be hauled to an approved disposal facility, by local code. The documentation of the hauled earthwork volumes by the contractor that provided this service can be provided. Before the excavation works started a diaphragm wall has been installed to prevent erosion effects of the surrounding soils and to minimize the disturbance of the groundwater level. Due to the redevelopment of the site, the infrastructure of a canalization system of the community of Milan was already in place to treat possible stormwater rates. Furthermore the project created paved site logistic roads to minimize the effect of vehicle and foot traffic. The planned landscaping of the project was planted as early as possible to stabilize the surrounding soils. Due to the given infiltration quality of the soils there were hardly any stormwater amounts that were running of site and if they did they were flowing into the existing canalization system. According drawings with the existing canalization system can be provided. Due to the documentation on hand we can show pictures and drawings of the site in it\'s early stages. The erosion and sedimentation measures can only be described now, and proven through the scope of services contract with the earth work company that disposed the volumes and through pictures and drawings showing the site and the infrastructure of the early stages of the construction. We kindly ask you to review the points mentioned above and give us your feedback if the project can achieve this prerequisite based on the information given above.
From the project description given, it is not clear what standards were followed or whether an Erosion and Sedimentation Control Plan was developed for construction. More information will be required for prerequisite review. The strategies outline above do not address all of the areas for erosion and sedimentation control required to meet the prerequisite. The strategies implemented to control sedimentation and erosion should be implemented on the project site during construction. For certification, the project team must provide a copy of the Erosion and Sedimentation Control Plan. If an Erosion and Sedimentation Control Plan was not created, the project must demonstrate that erosion and sedimentation control measures implemented met or exceeded the requirements of the 2003 EPA Construction General Permit, and must address at a minimum: 1. Strategies implemented on the construction site to control soil loss from stormwater and wind during construction 2. Strategies implemented on the construction site to protect receiving storm sewers and receiving water ways 3. Strategies implemented on the construction site to prevent air pollution from dust and particulate matter. If the project can demonstrate that measures implemented conform to Construction General Permit requirements and the objectives identified in the prerequisite, the prerequisite may be achieved.
