WSB will perform field data collection along Kaparia Avenue (CP 21-01) and along the 10 miles of local streets programmed for rehabilitation in 2021 (CP 21-02). WSB will use the data to create topographic surveys. The topographic surveys will assist City staff in completing the designs and preparing final plans and project specifications. Primary Issues to Consider • WSB’s proposal identifies the scope of services and estimated cost to complete the work and is subject to the Master Agreement for Professional Engineering Services between the City and WSB approved by the City Council on July 18, 2016.

Project Approach/Scope of Services WSB’s project scope and proposed tasks are based on our understanding of the project, and we propose the following scope of services: Topographic Survey (CP 21-02): This work includes topographic survey data collection along 10.14 miles of mill and overlay streets, as identified in the attached. Cross-sections will be completed every 50 feet along the roadway to a distance 10-feet beyond the back of curb. Data will be collected on both sides of all driveways at back of curb and 10 feet beyond and will identify driveway type. WSB will survey all surface utilities, including: gate valves, hydrants, manholes, CB’s and private utility boxes. No invert data will be collected with this topographic survey work. No geotechnical investigation coring/boring locations will be surveyed. All existing pedestrian curb ramps will be surveyed for replacement design purposes. In addition, the following work will also be completed in conjunction with the topographic survey: • Control points – WSB will establish survey control points on the project, which will eventually be utilized for the construction staking. Control points will be placed beyond expected construction limits so that they can be utilized during construction. Enough control points will be placed on the project so that if certain control points are vandalized or otherwise lost, the control can easily be re-established. Control points will be set up using Dakota County coordinates. Published benchmarks will be utilized for vertical control. • Utility location – WSB will submit a GSOC ticket to assemble utility information which will be collected during the topo. • Cross section data – WSB will collect cross section point data at 50-foot stations, all driveway locations and where the topography changes between 50-foot stations.

Included in the cross- sectional data should be existing street centerline, roadway edges (top and bottom curb shots), top and bottom of retaining walls and every change in grade of the cross section. Shots will be taken of any existing ditch sections. • Topographic features – WSB will provide shot data for all surface topographic features including but not limited to: trees, tree lines, mailboxes, driveway edges, landscape edges, private and public utility locations, hydrants, manholes, catch basins, inverts of flared end sections, culverts, gate valves, roadway edges, street signs, light poles and retaining walls. Topographic Survey (CP 21-01) This work includes topographic survey data collection along 2,600 feet of Kaparia Avenue. Cross sections will be completed every 50 feet and will include the ditch section and all culverts – as the project includes culvert replacement and ditch grading work. City Staff will meet WSBs survey crew on-site prior to starting this survey work to identify culvert locations. • Control points – WSB will establish survey control points on the project, which will eventually be utilized for the construction staking. Control points will be placed beyond expected construction limits so that they can be utilized during construction. Enough control points will be placed on the project so that if certain control points are vandalized or otherwise lost, the control can easily be re-established. Control points will be set up using Dakota County coordinates. Published benchmarks will be utilized for vertical control. • Utility location – WSB will submit a GSOC ticket to assemble utility information which will be collected during the topo. WSB will provide the City will all utility service provider maps collected as a part of the GSOC ticket request. • Cross section data – WSB will collect cross section point data at 50-foot stations, all driveway locations and where the topography changes between 50-foot stations. The cross-section data will extend 10 feet beyond the back of curb. Included in the cross - sectional data should be existing street centerline, roadway edges (top and bottom curb shots), top and bottom of retaining walls and every change in grade of the cross section. Shots will be taken of any existing ditch sections. • Topographic features - Provide shot data for all topographic features including but not limited to: trees, tree line, mailboxes, driveway edges, landscape edges, private and public utility locations, hydrants, manholes, catch basins, inverts of manholes, inverts of catch basins, inverts of flared end sections, culverts, gate valves, roadway edges, street signs, light poles and retaining walls. • We are available to start on this topographic survey work within 1 week of notice to proceed. Our work plan includes starting with a 1-person survey crew start and stay on the project and have other crews come in to supplement as time and workload allows.
