Base Mapping. The City will provide base mapping for the project based on a ground topographic survey, including utilities, existing right-of-way (highway boundary lines), existing easements, approximate property lines, reputed owner names and addresses and existing contours at 0.25 foot intervals. The Consultant will be responsible for:
Base Mapping. Based on the findings from previous tasks, we will develop the base map for the design of the project. We will do this by incorporating the topographic survey, boundary mapping, utility information, record drawings, atlas maps, archeologic investigations, habitat mapping, and other applicable information in developing precise locations and alignments for the proposed improvements and facilities.
Base Mapping. The field data will be reduced and the design survey base map will be completed. A surface will be created and contours shown in the design survey. The
Base Mapping. Information win be compiled in digital Microstation & AutoCAD format at a horizontal scale suitable for the proposed roadway and bridge design improvements.
Base Mapping. Prepare topographic mapping in Civil 3D 2021 at a 1” = 20’ scale, 11”x17”. Topographic features will be depicted using standard symbols. Topographic features will be shown on the design plans. Locations (X & Y coordinates) and elevations of local TBMs will be shown. Street ROW will be shown based on the CITY’s G.I.S. mapping. Water system and water service will be shown based on CITY’s G.I.S. mapping and as marked by the CITY in the field. Storm drainage systems will be referenced based on ACHD’s available G.I.S. information and field survey of visible storm drainage facilities. Roadway will be cross-sectioned at 50’ to 100’ intervals, on centerline, edge of pavement, gutter, top of curb and natural ground near ROW. Property addresses and ownership will be shown from available GIS information adjacent to the project corridor.
Base Mapping. SEI will prepare a base map of the project area using field survey collected, as-builts, CAD files provided by the City and utility information from the landfill. This base map will show existing property lines, topography, utilities and existing surface improvements. Task 1.3 – Construction Documents: SEI will prepare the design, specifications and construction documents for the new drainage pipe. These plans are anticipated to include:
1. Cover Sheet
2. Legend, Index & Notes
3. Plan & Profile Sheets (20-scale) – installation of drainage pipe by slope pinning
4. Add-Alternate – Installation drainage pipe by burying.
5. Detail Sheet(s) This proposal assumes that the plans will be submitted to the City at the 30%, 60% and 90% stage for review and comment.
Task 1.4 Drainage Memo: SEI will perform a drainage analysis of the site to determine the peak runoff of the landfill site at closeout for the 100-year storm event using current NOAA 14 rainfall. The drainage analysis will also include storm drain and perimeter drainage swale sizing in support of the construction plans.
Task 1.5 Engineers Opinion of Probable Cost: SEI will prepare an itemized opinion of probable cost for the project. This will include separate options for either burying the pipe or pinning the pipe to the landfill slope.
Base Mapping. Consultant shall create a base map to support the development of alternatives for each of the project locations, corridors, and surrounding areas. Because detailed engineering design is not included as part of this feasibility study, topographic survey and right of way retracement is not included. Use of existing databases such as the City of Bend’s GIS data, aerial imagery, LIDAR data, and field verification are all be acceptable methods, subject to final confirmation between the Consultant and the City. Field verification will consist of one (1) crew for up to three (3) days. Field verification may include establishing control and confirming information included in the existing databases. Consultant shall use the Oregon Utility Notification Center to submit requests for utility locate maps for the project area. The locations of underground, surface and overhead utilities shall be inventoried for the alternative’s analysis and feasibility study portion of this scope of work.
Base Mapping. The MIG Team will create maps of the planning area that include regional context, community facilities and amenities, major transportation infrastructure, existing transportation services (e.g. transit, bike/ped facilities, and ferry service), and relevant demographic and socioeconomic information.
Base Mapping. CHA will update the Town of Avon’s existing trail and sidewalk GIS mapping database. The Town of Avon will provide CHA with the existing GIS layer information including but not limited to boundaries, existing trail and sidewalk line work, land use, parcels, roads, utilities etc. CHA will then verify the information provided is current and make necessary updates based on available information. Assumptions: We assume an updated GIS map will be available from within two (2) years of project start and that some aspects of the map will need field verified.
Base Mapping. All spatial information is registered to the Terrain Resource Inventory Mapping (TRIM), North American Datum (NAD) 83 base using the Xxxxxx projection. Inventory data has been prepared using the ARC/INFO™ Geographic Information System (GIS). Use of GIS ensures that spatial relationships between the various inventory attributes are maintained throughout the analysis process. One example is existing roads and streams have been buffered to provide specific area reductions from the THLB. Another example is the classification of THLB vs. non-THLB productive land base. Forest on the non- THLB productive land base is not available for harvesting but can contribute to forest cover objectives for non-timber resources (depending on its structural state).
