For an all-inclusive impact summary refer to Appendix G for the I-95, Section 200 Wetland
Impact Matrix that identifies permanent and temporary impacts for all wetland systems
identified within the study area.
Express Toll Lanes Alternative
This alternative (including MD 152 Option 4A, MD 24 Option 2, MD 543 Option 7, and
MD 22 Option 1) would permanently impact 1.3 acres of wetlands and temporarily impact 1
acre of wetlands. All temporary impacts are associated with the construction of the
alternative, and were determined using a 25 foot buffer from the proposed LOD for this
alternative. Please refer to Appendix B, Plates 33-65 for the locations of the wetlands in
association with the Express Toll Lanes Alternative. Impacts to wetlands for each
interchange option are listed in Table III-12.
The following summarizes some of the impacts to wetlands associated with the Express Toll
Lanes Alternative:
• All 0.368 acres of wetlands within the current I-95/MD 152 Interchange would be
filled due to the interchange enhancements (Appendix B, Plate 41).
• All WET-18B (0.068 acres) would be impacted as a result of upgrades to the MD 152
exit ramp from I-95 southbound (Appendix B, Plate 42).
• Construction of interchange ramps would permanently impact wetlands within the
immediate vicinity of the I-95/MD 24 Interchange. A total of 0.072 acres would be
impacted at the following wetlands: WP024, WP001, WP002, WP003, WP004,
WP004A, WP004B, and WET-25B. (Appendix B, Plates 44-46)
• Roadway widening would necessitate all 0.177 acres of WET-6C to be filled
(Appendix B, Plate 50).
• In addition to 0.042 acres of temporary construction impacts, WET-7C (0.030 acres)
would be permanently impacted due to the roadway expansion (Appendix B, Plate
50).
• WET-3D and WET-4D would be impacted due to roadway widening. The impacts
will total 0.053 acres (Appendix B, Plates 53). Also, both WET-5D and WET-18D
