• Location of all surface evident street monumentation within the mapping corridor (for preservation and Record R/W purposes). • Location of underground utility locator markings. • Provide a finished draft topographic survey for each area of work. • Provide AutoCAD Civil3D DTM surface for each street section. • Any observed water meter or sewer cleanout behind the back of walk (up to 5' behind walk) will also be surveyed. The topographic data to be collected for intersections of Aurora Dr and Walnut Drive, and at Monterey Blvd and Anza Way will follow the same scope as above, with the following exceptions: • Topographic survey will extend 100' beyond curb returns where bulb outs are to be constructed and 50' into all other adjacent streets. • Cross-sections at 25'-50' intervals along with detailed surface topography and/or additional spot elevations as required defining the longitudinal and cross slope grade breaks. Topographic survey information for Hesperian Boulevard and Grand Avenue were provided by the City in December 2019. After further review, the topographic survey file for Grand Avenue is lacking much of the general and detailed information necessary for the proposed design project and a new survey is recommended. The survey provided for Hesperian Blvd has adequate general data and will require additional survey to missing information such as, but not limited to full roadway cross sections, storm and sewer structure elevations, and extending limits of survey to what is needed for the project design. Consultant's topographic surveyor will conduct spot checks of the Hesperian survey file to verify information is still accurate and complete. Underground utilities collected by Consultant's private utility locator will also be added to the Hesperian survey drawing. Based upon a combination of record data and any monuments collected during topographic surveying, consultant will calculate the record data location of the existing right-of-way for the mapping corridor. Additionally, consultant will calculate and show the location of each adjoining parcel lot line from record data (assessor's parcel data, record mapping and apparent lines of occupation). It should be noted this property line data will not be based upon a field survey and should be considered approximate only. Based on topographic survey data with existing right-of-way, consultant will develop preliminary design documents that depict basic street and/or pedestrian crossing improvements layout, and preliminary pavement treatments with pertinent geometric information. Consultant will submit preliminary technical specifications and an engineer's estimate. It is assumed that the City will require a 10 -day review/comment period once the preliminary PS&E package is submitted. Consultant has assumed that the City will be able to provide the following: 1. Upfront specifications including General Provisions and Special Provisions. 2. City Standard Provisions and Standard Design Criteria. 3. Electronic files of City cover sheet template, if preferred. Deliverables: Topographic Survey, Six (6) full size and an electronic version Preliminary Plan Sets, outline of Technical Specifications, and Engineer's Estimate (PS&E).
