Identify environmental resources and SCEA issues in the project area. (Directly impacted resources are the starting point. More resources may be identified based on secondary impacts or if new alternatives, with other/new impacts, are looked at.) Coordinate with resource agencies to: -obtain input on resource identification and analysis methodologies -inform them of missing information which could become an obstacle -seek their approval Incorporate into project planning process during preliminary alternatives development.

Secondary & Cumulative Effects Analysis Training Program Module 1: How to Determine Which Resources Should be Considered in a SCEA Middle River Employment Center Access Study (MRECAS) Purpose of the Project: To improve access from regional transportation network to enable planned economic development. To increase utilization of established employment areas in the Middle River Employment Center. Need for the Project: There is a need for a sufficient level of access and mobility for the Employment Center. Support of economic development. Existing roads in the study area lack the capacity and continuity to provide adequate access to the entire MREC from the existing highway network.

Secondary & Cumulative Effects Analysis Training Program Module 1: How to Determine Which Resources Should be Considered in a SCEA MD 5 - Hughesville Transportation Improvement Project The purpose of the MD 5 - Hughesville Transportation Improvement Project is to alleviate congestion and to address safety hazards along MD 5 at the MD 5/MD 231 intersection in the Hughesville area. MD 5 through Hughesville experiences a high accident rate due to a constrained typical section, limited capacity at the MD 5/MD 231 intersection, and numerous driveways with direct access onto MD 5. Traffic congestion and safety along MD 5 during morning and evening rush hours have become significant problems in recent years and conditions are expected to increase to 85 percent with the projected growth by year 2020 near Washington D.C., Lexington Park, and along the MD 5 corridor. The MD 5/MD 231 intersection currently operates at LOS "F" in the evening peak hour.

Secondary & Cumulative Effects Analysis Training Program Module 1: How to Determine Which Resources Should be Considered in a SCEA MD 5 - Hughesville Transportation Improvement Project No-Build - This alternative would not provide any significant improvements to MD 5 in the Hughesville area. Minor improvements would occur as part of normal maintenance and safety operations. These improvements would not measurably affect roadway capacity or reduce the accident rate. Possible minor improvements include items such as curbing, sidewalks, striping, signing, lighting, rumble strips and additional drainage. Alternatives Retained for Detailed Study

Secondary & Cumulative Effects Analysis Training Program Module 1: How to Determine Which Resources Should be Considered in a SCEA MD 5 - Hughesville Transportation Improvement Project Widen Existing MD 5 - This alternative proposes widening existing MD 5 to a seven-lane curbed section, with two through lanes and an auxiliary right turn lane for both the northbound and southbound directions and a continuous center left turn lane. This alternative would have three northbound and southbound lanes near the MD 5/MD 231 intersection. The posted speed limit would be 40 miles per hour (mph), similar to existing MD 5. This alternative requires the additional widening of MD 5 at the MD 5/MD 231 intersection. The widening creates the necessary storage to efficiently move peak hour traffic through the MD 5/MD 231 intersection. Alternatives Retained for Detailed Study

Secondary & Cumulative Effects Analysis Training Program Module 1: How to Determine Which Resources Should be Considered in a SCEA MD 5 - Hughesville Transportation Improvement Project Eastern Bypass - This alternative is a four-lane divided highway located east of MD 5 from south of Gallant Green Road to north of Carrico Mill Road. The Alternative 5 design speed is 60 mph. This alternative bypasses the town of Hughesville to the east. Alternative 5 is access controlled, providing only three points of access to the town of Hughesville. These points of access are at either end of the bypass and at MD 231, where a diamond interchange is proposed. The controlled-access Alternative 5 would safely and efficiently accommodate the 90 percent through traffic projected for this facility. Construction of the bypass will also safely accommodate traffic on existing in Hughesville. By intercepting the high volume of through traffic traveling between Calvert County and Lexington Park prior to Hughesville. Alternatives Retained for Detailed Study
