e e additional storm water runoff from this project, it was determined that no significant impact would be made to Little Cedar Bayou based on a 1 DO-year storm. RIECOM MENIOA 1rIONS Right-of-Way - No right-of-way acquisition will be required along Fairmont Parkway. However, several corner cutbacks are recommended to facilitate construction of generous turning radii to accommodate truck traffic. The cutbacks include all four corners of 16th Street, all four corners of 14th Street, the southwest corner of 13th Street, and the two corners on the west side of SH 146. Along 16th Street, additional right-of-way will be required within the first three blocks, both north and south, along the east side of the road. The additional right-of-way is neaded to construct the four-lane divided road section at the intersection which then transitions back to the existing two-lane roadway approximately 800' both north and south of Fairmont Parkway. Pan,ing - The pavement design for Fairmont Parkway will be six-lane divided concrete with curb and gutter (3 lanes in each direction). There will also be five turning lanes at the following locations: 1. Eastbound Fairmont Parkway at 16th Street (left turn) 2. Eastbound Fairmont Parkway at 14th Street (left turn) 3. Eastbound Fairmont Parkway at 13th Street (left turn Kroger Center) 4. Eastbound Fairmont Parkway at SH 146 (right turn) 5. Westbound Fairmont Parkway at 16th Street (right turn) Please note that the existing mandatory left turn lane median opening at 1 t" Street, leading into the Kroger Center, will be eliminated. An item of particular interest is that the engineer that prepared the Traffic Impact Analysis observed a significantly higher number of vehicles using the 1 j" Street entrance instead of the 1 i" Street entrance. The six-lane roadway will transition back to the existing four-lane roadway approximately 500' west of 16th Street. 16th Street will be a four-lane concrete road with open ditch drainage. This design will extend for approximately 800' both north and south of Fairmont Parkway before 16th Street transitions back to the existing two-lane roadway. Drainage - Reinforced concrete pipe and concrete box culverts will be used for this project. The pipe sizes will range from 18" to 60" and the boxes will range from 6'x3' to 8'x4'. The Fairmont Parkway median ditch from 14th Street to the UPRR tracks will be used for storm water detention. The existing 54" storm sewer along the south side of Fairmont parkway, between SH 146 and 14th Page 3 of 5
