The mapping will include features such as fences, lights, buildings, sidewalks, outline of landscape areas, outline of wooded areas, isolated trees over 6” in diameter, etc. 3. Locate and provide rim elevations for castings (manholes, catch basins and curb inlets) within the project limits, including those just beyond the curb line. 4. Detail sanitary and storm structures to determine invert elevations, flow direction, type and size of pipes. 5. Known subsurface utilities will be depicted based on the field survey of surface markings provided by Indiana Underground Plant Protection Service. 6. Create topographic base map from the survey data. 7. Right of way/property lines based on available field investigation and recorded subdivision plats, apparent right of way will be shown for any areas lying outside of a subdivision. Lot lines will be depicted per the recorded subdivision plats or GIS information. B. Boundary survey will be performed in accordance with the minimum standard requirements for retracement surveys per 865 IAC 1-12. A Plat of Survey will be prepared at a suitable scale and will be signed and stamped by an Indiana Professional Land Surveyor.
