Rhode Island Coastal Resources Management Program Original Edition Page 1 Section 300.13 Section 300.13. Public Roadways, Bridges, Parking Lots, Railroad Lines and Airports A. Definition 1. For the purposes of this program, public roadways shall be defined as all roadways other than private driveways used to access either public or private roads. 2. The requirements of this section apply to all new roadways, highways, bridges, parking lots, railroad lines, and airports. Alterations and improvements to roadways, highways, bridges, parking lots, railroad lines, and airports are subject to the erosion control requirements contained in this section and Section 300.3. Alterations and improvements to roadways, highways, bridges, parking lots, railroad lines, and airports that result in new stormwater discharges or increase storm- water discharge volumes beyond pre-development levels are subject to the stormwater management requirements contained in Section 300.6 (excluded from these requirements are projects consisting only of pavement resurfacing, minor roadway repairs, or emergency drainage repairs). B. Prohibitions 1. The construction of new public transportation facilities in tidal waters and on coastal features is prohibited with the following exceptions: (a) construction on developed barrier beaches may be permitted, subject to the requirements of Section 210.2; (b) unpaved vehicle trails and parking areas may be permitted on undeveloped barrier beaches (Section 210.2); and (c) construction may be permitted on manmade shorelines subject to the requirements of Section 210.6. C. Policies 1. All roadways, highways, parking lots, railroads lines, and airports shall be planned, sited, and designed to: i) protect areas that provide important water quality benefits or are particularly susceptible to erosion and sediment loss; ii) limit land disturbances such as clearing and grading and cut and fill to reduce erosion and sediment loss; iii) limit disturbances of natural drainage features and vegetation; and iv) limit the increase of impervious surface areas, except where necessary. 2. All bridge structures shall be sited, designed, and maintained so that sensitive coastal habitat areas such as coastal wetlands and areas providing important water quality benefits are protected from adverse effects. D. Standards 1. See standards given in "Filling, Removing, or Grading of Shoreline Features" (Section 300.2). 2. Permeable materials shall be utilized, where practicable, to surface roadways and parking lots on shoreline features adjacent to Type 1, 2, and 3 waters. 3. Applicants shall reduce erosion and, to the maximum extent practicable, retain sediment on- site during and after construction. Applicants shall prepare and implement an erosion and sediment control plan in accordance with all of the policies and standards contained in Section 300.2. 4. Applicants shall prepare and implement a stormwater management plan in accordance with the policies and standards contained in Section 300.6. 5. See the standards contained in "Treatment of Sewage and Stormwater (Section 300.6)".
