A copy of the proposed masterplan is included in Appendix A. This report addresses Statutory Utilities only (electric, gas, telecoms and water and foul drainage), and does not include any “privately” owned and maintained utility infrastructure that may or may not be present on site. Site Location 1.2.1 The proposed site is currently greenfield agricultural land. The land is bounded to the north by Netherhampton Road, to the east and west by existing retail units and to the south by greenfield land. A detailed site location plan can be found in Appendix B. The Report 1.3.1 This report has been prepared to consider the proposed utility infrastructure and any constraints the existing utilities may present to the proposed development. It provides the following information: The existing utility infrastructure in the vicinity of the development. Diversionary/protection works anticipated to the existing utility infrastructure to facilitate the development. Details of the responses received in respect to capacity enquiries. The utility infrastructure that would be required to supply the new development. 1.3.2 PBA approached the incumbent utility providers requesting that they undertake capacity and new supplies investigations based on everyday typical usage rates for 640 residential units. In addition, the following utility loading demands have been used for non-domestic units: Utility Medium Usage Potable Water Foul Drainage Peak Electricity (kVA)
