(a) The City Engineer or a designated representative shall inspect the construction of the temporary and permanent stormwater management system for the development site. The permittee shall notify the City Engineer forty-eight hours in advance of the completion of the following key development phases:
(1) At the completion of preliminary site preparation, including stripping of vegetation, stockpiling of topsoil and construction of temporary stormwater management and erosion control facilities.
(2) At the completion of rough grading but prior to placing topsoil, permanent drainage or other site development improvements and ground covers.
(3) During construction of the permanent stormwater facilities at such times as specified by the City Engineer.
(4) At the completion of permanent stormwater management facilities, including established ground covers and plantings.
(5) At the completion of final grading, vegetative control measures or other site restoration work done in accordance with the approved plan and permit.
(b) No work shall commence on any subsequent phase until the preceding one has been inspected and approved. If there are deficiencies in any phase, the City Engineer shall issue a written description of the required corrections and stipulate the time by which they must be made.
(c) If, during construction, the contractor or permittee identifies any site condition, such as subsurface soil conditions or alterations in surface or subsurface drainage, which could affect the feasibility of the approved stormwater facilities, he/she shall notify the Municipal Engineer within twenty-four hours of the discovery of such condition and request a field inspection. The Municipal Engineer shall determine if the condition requires a stormwater plan modification.
(d) In cases where stormwater facilities are to be installed in areas of landslide-prone soils or where other special site conditions exist, the Municipality may require special precautions such as soil tests and core borings, full-time inspectors and/or similar measures. All costs of any such measures shall be borne by the permittee.
