Delete IBC section 1608.1 General and substitute the
					 following:
1608.1 General.
Design snow loads shall be determined in accordance with
					 section   7     of ASCE 7 using the ground snow load values determined by Table
					 1608.1, but the minimum flat roof snow load shall be not less than that
					 determined by Table 1608.1. The design roof load shall not be less than that
					 determined by section 1607.
Delete IBC section 1608.2 Ground Snow Load.
Add the following to IBC section 1608 Snow Loads.
1608.2 Structural Loads.
When a new building is to be constructed or an existing
					 building extended to a greater height than an existing adjoining building, a
					 determination of structural integrity of the roof of the adjoining building
					 shall be made regarding the snow loads in accordance with section 1608.0 SNOW
					 LOADS. The person intending to cause the construction or building height
					 extension shall deliver written notice of intent to the owner of the
					 potentially affected building. The notice shall request license to enter the
					 potentially affected building to inspect and determine the existing building's
					 capacity to sustain additional imposed snow drift load. The person causing such
					 construction shall be liable and shall at their own expense preserve, protect
					 and, if necessary, reconstruct those portions of the adjacent building affected
					 by this construction. If the owner of the adjacent building refuses to allow
					 inspection, protection or reconstruction as may be required, the person causing
					 such new construction or building height extension shall notify, in writing,
					 both the Building Official and the owner of the adjacent property. Such
					 notification shall identify that the responsibility of providing inspection,
					 protection or reconstruction to the adjacent building has become the exclusive
					 responsibility of the owner of the adjacent property.
1609.3 Basic Wind Speed.
The basic wind speed, in mph, shall be determined by Table
					 1608.1.
Delete all IBC Figures 1609 and substitute Rhode Island
					 Wind Speed Map Figure 1609 and Figure 1609 (A), and Rhode Island frost
