To support the City’s due diligence and future planning efforts, a comprehensive land survey is required to establish accurate property boundaries, assess existing utilities, and provide critical data for maintenance and development decisions. Our team understands that the successful execution of this project requires precise, timely, and cost-effective surveying services to facilitate the property transfer and ensure that the City has reliable data for future site planning. The scope of work will include: BOUNDARY & PROPERTY LINE SURVEYS Establishing legal property lines for both the PONY Property and the Sunset Crossing Property to confirm ownership limits and identify any encroachments or easements. LEGAL DESCRIPTIONS AND PLATS Providing accurate documentation to facilitate legal transactions and City record-keeping. ALTA and NSPS LAND TITLE SURVEY Supporting the property acquisition process by ensuring compliance with national land surveying standards. (if required) TOPOGRAPHIC & UTILITY SURVEYS Identifying existing infrastructure, above-ground and underground utilities, and site features to aid in planning and maintenance efforts. We recognize that the City’s objectives extend beyond simple property acquisition—this survey will serve as a foundational tool for future improvements, zoning considerations, and potential redevelopment efforts. Our approach will prioritize accuracy, efficiency, and coordination with City staff to deliver high-quality survey data that supports the City’s vision for these properties. prOjeCT meTHOdOLOGY Onward Engineering (OE) provides a wide range of surveying services to various clients throughout Southern California. OE works on staying at the forefront of technology so that we can use the latest tools in performing accurate and efficient surveys for our clients. We understand that Land Surveying is important for accurately locating the built environment relative to it’s surroundings and legal boundaries. Overall, land surveying is essential for effective land management, sustainable development, and the efficient use of natural resources. It provides accurate spatial information that underpins many aspects of modern society, from urban planning and construction to environmental protection and economic development. We can perform many types of land surveys to suit the City’s needs. In general we offer the following services: TOpOGrapHiC SurveY A topographic survey is performed in order to collect the detailed information about an existing environment and plotted on a scaled map. The survey is meant to gather terrain information, vegetation, structures, visible utilities, grade breaks, and drainage patterns. OE performs a topographic survey using various tools in order to provide the most detail necessary for the City. This might involve cross sections at every 25’ or 50’ along a corridor to get detailed surface information. lasER scanning OE collects topography data and photos using a terrestrial laser scanner. The laser scanner is equipped with a high- speed 3D scanning system that measures 500,000 points per second and HDR 360-degree images. The advantage of laser scanning is it provides high density accuracy, fast data collection, and a clear representation of the existing conditions using a colorized point cloud of the site as shown in the sample image on the following page. SECTION D: Methodology and Project Understanding RFP for Professional Land Surveying Services for The City of Diamond Bar 16 The 3D point cloud produced allows linework to be quickly drafted and for a more accurate placement of objects for the existing utility appurtenances. Appurtenance geometry such as utility pole, fence and tree diameters are accurately documented as the entire circumferences of the objects are measured rather than the single point which is typically collected from a traditional survey. This allows a precise identification of ADA clearance issues to ensure an accurate design. DRonE maPPIng A site assessment is enhanced with the collection of high-resolution aerial photographs using our drone. Our team has three remote pilots licensed by the FAA to fly drones for commercial use. The aerial photographs allow us to accurately denote site surface features, areas of excessive pavement distress, utility notification markings, and street striping, as well as providing us with highly detailed reference data that cannot be achieved through traditional site evaluation methods. Additionally, the images collected are at a higher resolution than images provided by other sources and are ideal for use in the preparation of exhibits. The images below, collected for a previous project, demonstrate the level of detailed information that can be collected using drone technology. The aerial photos collected are consolidated in post-processing to create complete street segments with very high levels of detail. aSpHalt crackIngada ramp detaIl cEntERlinE & Right-of-way EstablishmEnt Land surveying for centerline and right-of-way establishment involves precise measurements and documentation to define the path of roads, highways, railways, or other transportation corridors, as well as the boundaries of the land allocated for their construction and maintenance. OE’s process involves researching existing maps and legal documents to determine the limits of the right-of-way, property boundaries, and easements. Our field crew then performs a field survey using a combination of GPS tools and conventional survey equipment to determine the centerline alignments and limits of the right-of-way. Our field SECTION D: Methodology and Project Understanding RFP for Professional Land Surveying Services for The City of Diamond Bar 17 crew then locates existing monuments along the corridor and references them to existing recorded maps. This survey is not a full boundary survey, but involves the field work necessary in determining the Centerline of the requested corridor. constRuction staking When performing construction staking, OE conducts a thorough review of the project plans, specifications, and relevant documents provided by the City and project stakeholders. We: •Coordinate with the City, Project Engineer, Contractor, and other parties involved to understand the project requirements and schedule. •Mobilize survey crews equipped with state-of-the-art surveying instruments, including total stations, GPS receivers, and data collectors, to the construction site. •Establish control points and reference benchmarks using precise surveying techniques for accurate georeferencing. •Conduct field surveys to stake out critical construction points, including curbs, centerlines, flowlines, utilities, drainage features, structures, and other project elements, as per the project plans and specifications. •Ensure that all staking is performed in accordance with applicable surveying standards, regulations, and best practices. monumEnt PREsERvation & coRnER REcoRDs Monument preservation and the preparation of corner records are crucial tools for maintaining established markers to be referenced for future land surveys and locating centerlines and property lines. Preparing a corner record in California involves documenting the establishment and location of property corners and centerline monuments for land parcels. Our survey crew meticulously gathers field data using advanced surveying equipment to accurately determine the coordinates and physical characteristics of each monument. This process typically includes researching historical records, conducting field surveys, and verifying monumentation to ensure the reliability and accuracy of the corner record. Once the necessary data is collected, our surveyors draft a detailed corner record document that includes a description of their monument type, dimensions, and relationships to adjacent features. The corner record is then submitted to the City for review and approval, and upon acceptance, it becomes an official record of the property corners for legal purposes. The corner record serves as a vital reference for property owners, land developers, and government agencies in delineating property boundaries and surveyed corners, allowing for clarity and certainty in land ownership, property rights, and reliable survey records. REcoRD of suRvEy maPs This involves documenting survey data to create an official record of property boundaries, land divisions, and other survey-related information. Our Surveyors conduct field surveys to accurately measure and delineate area boundaries and document survey monuments, property corners, and other boundary markers. Our team then compiles the data into a detailed map that depicts the surveyed boundaries, easements, encroachments, and other relevant features whilst checking conformance with state and local surveying regulations and standards, including specific formatting requirements and technical specifications, and incorporating all necessary legal descriptions, notes, and annotations. We then conduct quality control checks to identify, address and correct discrepancies or inconsistencies identified during the review process to achieve accuracy and integrity of the final map. Once approved, the map is signed and sealed by a licensed surveyor. tR act anD PaRcEl maPPing Tract and Parcel Maps define the subdivision of land into individual lots or parcels. Our Surveyors measure and delineate the boundaries of the tract or parcel, as well as any easements, etc. and then compile the collected data and draft a comprehensive map that depicts the layout and configuration of the subdivided land. For Tract Maps, which typically involve larger subdivisions, the map includes information about the layout of streets, blocks, lots, and common areas, as well as any applicable easements, dedications, or restrictions. Parcel Maps, on the other hand, focus on smaller subdivisions such as individual parcels with their respective boundaries, dimensions, and legal descriptions. SECTION D: Methodology and Project Understanding RFP for Professional Land Surveying Services for The City of Diamond Bar 18 The drafting of the maps must adhere to strict regulatory requirements and standards established by the California Land Surveyors Act, including specific formatting guidelines, scale ratios, and technical specifications. We also incorporate any necessary legal descriptions, annotations, or notes to provide clarity and context to the map. The map undergoes review, quality control, and is then signed and sealed, certifying its accuracy and compliance with surveying standards. The completed map serves as a legally binding document that defines the boundaries and ownership of the subdivided land parcels. tEmPoRaRy constRuction EasEmEnts OE establishes temporary rights-of-way and accesses permissions granted to construction crews or contractors for a specified period during the construction phase of a project. OE’s Survey crew defines the boundaries and terms of these temporary easements by conducting a thorough assessment of the construction site and project plans to determine the areas where temporary access or use of land is necessary. This assessment involves identifying potential obstructions, existing property boundaries, and utilities. OE then works closely with project engineers, developers, and landowners to determine the limits for the temporary easements. This involves drafting legal descriptions and exhibits of the temporary easements. We work closely with the City and Engineer to include the duration of access, permitted activities, compensation (if applicable), and any restrictions or requirements imposed by the landowner or regulatory authorities. prOjeCT SCOpe OF wOrk Onward Engineering will provide comprehensive Boundary/Property Line Survey and Utility Survey services for the PONY Property and Sunset Crossing Property in Diamond Bar.
