For Greenfield sites, the intent of this credit is to "conserve existing natural areas." Credit requirements recognize that there are a number of reasons for disturbing a given area during the construction/operation of a building and rewards the minimization of these disturbances. It should be noted that NCv2.1 CIR Ruling dated 9/19/2005 allows for a budget-based compliance path and therefore limits of disturbance (including those addressed below) can actually exceed the prescribed limits, given the guidance of the CIR. For this Greenfield site; 1) Are retaining walls considered an allowable disturbance, or must they be located within the limitations of disturbance? Retaining walls must be located within the disturbance limits of the site and building components listed in the credit requirement language. If a building foundation wall is also a retaining wall, the 40\' limit of disturbance would apply. 2) Are landscaped areas considered an allowable disturbance? Landscaped areas are disturbed areas and must fall within limits of disturbance. 3) When constructing roadways, is there an allowance beyond credit requirements of 15\' beyond the curbline? No, roadway construction must be limited to a disturbance zone of no more than 15\' beyond the curb. 4) Are there any exceptions to the prescribed limits of disturbance? NCv2.1 CIR Ruling dated 9/19/2005 allows for limited exceptions to the prescribed limits of disturbance through the use of a budget-based compliance path. No other exceptions are allowed. Applicable Internationally.
