Gregory Avenue and Lowell Avenue Safe Routes to School Preliminary Engineering, Final Design, and Construction Engineering Services Page 5 Preliminary Engineering – Scope of Work b. Prepare Preliminary Roadway Plans (3070) The preliminary roadway drawings will be prepared to a level of detail required to clearly indicate resulting impacts, including any ROW, private property, cartway, crosswalk, curb alignment, sidewalk, ADA ramps, driveways, and associated impacts. In addition to the horizontal and vertical geometry, the preliminary roadway plans will include sidewalk, curbing, ramps, driveways, hydrants, utility poles, lights, trees, street features, grading, existing drainage and stormwater management facilities, traffic engineering facility locations, right of way and private property impacts. As part of the Preliminary Roadway Plan development, the development of alternate critical cross-sections to depict potential roadway design elements such as lane, shoulder, and border widths, and cross slopes will be performed. These sections will show and provide dimensions for roadside details such as sidewalk, ADA ramps, sidewalk enhancements, cut and fill slopes, ROW line, roadway width, and associated improvements. They will be used to identify and quantify impacts. The full set of preliminary plans that will be drafted under this task may include the following: Roadway: • Key Sheet (1 Sheet) • Construction Plan Legend (1 Sheet) • Estimate-Distribution of Quantities (1 Sheet) • Construction Plans (4 Sheets) • Curb ramp layout details (5 Sheets) • Typical Sections (2 Sheets) • Preliminary Signing and Striping Plans (4 Sheets) • Soil Erosion and Sediment Control Plans (4 Sheets) • Pedestrian Flashing Beacon Plan (4 Sheets) • Preliminary Staging/Maintenance and Protection of Traffic/Detour Plans (8 Sheets) • Tie Sheets (2 Sheets) • Construction Details (10 Sheets) • Electrical Details (2 Sheets) Other:

ic/Detour Plans (8 Sheets) • Tie Sheets (2 Sheets) • Construction Details (10 Sheets) • Electrical Details (2 Sheets) Other: • Utility Relocation Plans (4 Sheets) 3. TRAFFIC a. Determine Traffic Engineering Facility Locations (3090) STV will establish the pedestrian flashing beacon location layout. STV will prepare conceptual level plans for the layout of lighting design, signs, regulatory traffic control devices and flashing beacon design to determine any associated right-of-way or easement needs. STV will also identify and resolve any potential underground or aerial utility conflicts. STV will coordinate with the municipality and investigate converting Lowell Avenue to a one-way street to enable the sidewalk to be built completely within the existing cartway. 4. DRAINAGE / H&H / SWM a. Prepare Preliminary Drainage Design (3085) There are limited drainage structures within the project limits. The existing inlets conditions will be evaluated. Bicycle safe grates and curb pieces will be installed at all substandard inlets within the project
