iv. Traffic Signals: Not Included v. Sidewalks: Existing sidewalks will remain, as possible, and FNI will determine completion of sidewalk along the remaining corridor as determined by the complete street analysis. vi. Intersection with River Road Alternatives: FNI will evaluate 2 intersection alternatives for the intersection of Uhland Road and River Road to improve safety and the operational efficiency of the intersection. F. San Marcos Electric (SMEU) i. Underground Conduit: Not Included ii. Photometric for Street Lighting: Not Included iii. Coordination: FNI will evaluate impacts on the SMEU and will coordinate design improvements with SMEU. G. Drainage i. Watershed Analysis: Not included in this contract. FNI will obtain the latest available HEC-RAS model of the Blanco River from the City and use this model to evaluate tailwater conditions as described below. ii. Determine Alignments: FNI will evaluate installing a storm drainage system that outfalls to the Blanco River and will evaluate up to two alternatives (one potential new alignment)that will improve local drainage and avoid adverse downstream impacts per criteria outlined in the City of San Marcos drainage criteria. This will include preparation of up to two alternative preliminary plan-view alignments and supporting rational method calculations, to be summarized in a preliminary engineering report. iii. Preliminary Hydraulics/Modeling: FNI will determine if the University Heights system can handle the existing and additional flows from the roadway improvements while meeting City drainage criteria. Because portions of the project are in the Blanco River floodplain, and because the Blanco River basin is much larger than the local system's drainage area, FNI will analyze the local system based on the expected coinciding tailwater. FNI will estimate the coincident tailwater using the latest available HEC- RAS model of the Blanco River, and compare with coincidental occurrence guidance from the TxDOT Hydraulic Design Manual. iv. Water Quality: FNI will evaluate opportunities to incorporate pretreatment manufactured devices prior to discharge to the Blanco River. H. Determine Easement/Land Acquisition Requirements i. Prepare Exhibits: Easement and right-of-way documents will include exhibit and metes and bounds description for up to 10 parcels (assuming each less than 0.25 acre/parcel).
