PRELIMINARY DESIGN SUMMARY. An executive summary will be prepared with scaled drawings/exhibits containing: 1. Proposed horizontal alignment and its impact(s) on existing ROW 2. Proposed vertical alignment impact on the existing businesses, street system, traffic circulation, and accessibility to future overpass 3. Evaluation of roadway and bridge typical sections including pedestrian amenities 4. Identifying the drainage outfalls along US 90A within the project limits with preliminary drainage impact on the existing storm sewer conveyance within the study area. 5. Preparation of preliminary bridge sections and bridge layout to span the following: a. UPRR ROW and, ▇. ▇▇▇▇▇▇▇ Street ROW It must be noted that this analysis will evaluate the proposed bridge approximate dimensions for bridge length, bridge width, span length and span type for the bridge openings mentioned in item 5a & 5b. In addition to the UPRR required 23’- 4” vertical clearance from top of rail, the structure should provide a minimum of 25-ft horizontal clearance from nearest centerline of each track to avoid installing crash proof walls in front of the proposed columns/supports. 6. Identification of existing utilities along US 90A and preparation of utility conflict table for any/all potential utility conflict within the project limits. 7. Preparation of the preliminary construction cost estimate associated with the engineering recommendations. 8. Prepare existing condition and proposed traffic signal configuration for the FM 762/10th Street traffic signal. 9. Conceptual traffic control & construction phasing plan 10. Prepare 30% complete plans which will include roadway & bridge horizontal and vertical geometrics, preliminary drainage layout, sight triangles and sight distances.
