LiDAR tree and streetscape inventorying services throughout the City, including public and private property in Fremont. **Solicitation Type**: RFP - Request for Proposal (Formal) **Source ID**: PU.AG.USA.2689338.C17694751 **Piggyback Contract**: No **Question Acceptance Deadline**: 03/31/2026 06:00 PM EDT **Questions are submitted online**: Yes **Bid Submission Type**: Electronic Bid Submission **Solicitation Number**: 26-010 **Reference Number**: 0000417473 **Pricing**: In attached document **Bid Documents List**: | Item Name | Description | Mandatory | Limited to 1 file | |---|---|---|---| | Bid Documents | Documents defining the proposal | Yes | No | **Questions and Answers**: - Q1 Arrow Right Question: RFP 26-010 – Clarification Questions 1. Is the base scope limited to public rights-of-way and City-owned or City-managed parks and facilities, with private-property tree canopy analysis treated as an optional or add-alternate service? 2. “The city also maintains an interest in potentially analyzing and benchmarking trees and tree canopy coverage on private property within urban city limits through aerial or satellite imaging. “ Does the City have recent data that will be made available for this service (if so, what is the type and recency of collection)? If not, should this be priced as an optional service? 3. For non-tree streetscape features, which specific features are required in the base scope versus optional (e.g., streetlights, signs, sidewalks, curbs, pavement conditions)? 4. Can the City provide authoritative GIS layers (street centerlines, ROW extents, park and facility boundaries) to define the approximately 500 miles of streets and 1,000 acres of parkland for estimating purposes? 5. Can the City provide authoritative GIS layers (shapefile, GDB, KML, etc.) that power the current TreePlotter Inventory site for estimating purposes? 6. The current TreePlotter inventory lists 80,228 trees. How accurate/up to date is this data? Does the City have an estimate of the current number of trees? 7. What is the positional accuracy of the current TreePlotter inventory? We assume a new lidar collection will provide more accurate results. Is there an expectation that existing points will need to be adjusted to fit the updated dataset? 8. Should alleys, private roads, internal park roads, parking lots, and trails be included within the project limits? 9. Please define minimum required positional accuracy (horizontal and vertical) and any minimum LiDAR point density or imagery resolution requirements. Answer: Answered in Communication 2 03/26/2026 11:02 AM EDT 04/06/2026 12:32 PM EDT - Q2 Arrow Right Question: RFP 26-010 – Clarification Questions 2 10. For attributes such as species, canopy condition, trunk condition, pests/disease indicators, girdling roots, and fruiting bodies, does the City accept LiDAR- and imagery-based inference with confidence scoring, or is field verification by certified arborists required? 11. The RFP specifies DBH measured to the nearest tenth (0.1) of an inch. Is this intended as a reporting precision or as a required accuracy standard? If an accuracy requirement, what tolerance is acceptable and how will it be validated? 12. For conflicts with utilities, signs, and streetlights, does the City require simple presence/proximity classification, or clearance-based conflict thresholds? If thresholds apply, please define them. 13. For high-definition photos and high-resolution panoramic images, please define minimum resolution, capture interval, and whether a unique panorama is required for each individual tree or if corridor-level imagery may be associated to nearby trees. 14. Please clarify the expected format and level of detail for required 3D tree models (e.g., classified point cloud subsets, meshes, parametric models). 15. What criteria or tolerance defines an ‘accurate representation’ of tree structure for acceptance purposes? 16. What level of integration with the City’s TreePlotter system is required: import-ready datasets, configuration of TreePlotter fields/layers, API-based synchronization, or a separate interface that links to TreePlotter? 17. Will the City provide TreePlotter data schemas, domain values, and (if applicable) API documentation and a test environment for validation prior to final delivery? 18. Please define acceptance criteria for completeness, positional accuracy, and attribute accuracy, including required sampling rates, validation methods, and rework thresholds.

Please define acceptance criteria for completeness, positional accuracy, and attribute accuracy, including required sampling rates, validation methods, and rework thresholds. 19. Please define the expected duration, scope, and service levels for ‘ongoing technical support’ following project acceptance, including response times and whether enhancements are included. Answer: Answered in Communication 2 03/26/2026 11:03 AM EDT 04/06/2026 12:32 PM EDT - Q4 Arrow Right Question: Tree Volume p. 13 - Does the City have an estimate of the volume of trees which are visible from public drivable roads and those which are located within pedestrian only areas such as city parks? Answer: Answered in Communication 2 03/27/2026 10:35 AM EDT 04/06/2026 12:32 PM EDT - Q5 Arrow Right Question: Tree Plotter Integration p. 15 - Can you please elaborate on your expectations for the integration with TreePlotter? For example: Would providing a shapefile with the digital inventory attributes for import into TreePlotter be sufficient? Alternatively, is the expectation that selecting a tree within TreePlotter would then open up the panoramic image nearest the tree and corresponding LiDAR data in separate software (“interface” described in Deliverable A)? Answer: Answered in Communication 2 03/27/2026 10:36 AM EDT 04/06/2026 12:32 PM EDT - Q6 Arrow Right Question: Pricing/Cost p. 17 - We note that Price/Cost has not been included within the Selection Criteria.

Answer: Answered in Communication 2 03/30/2026 02:27 PM EDT 04/06/2026 12:32 PM EDT - Q8 Arrow Right Question: Collection Fields The following fields listed in the RFP are typically assessed and collected in-person with a full 360 degree assessment around the tree, how does the city expect these to be assessed remotely and to what degree of confidence is expected? Primary maintenance needs Presence of girdling roots Presence of fruiting bodies Presence of broken/hanging limb Answer: Answered in Communication 2 03/31/2026 12:08 PM EDT 04/06/2026 12:32 PM EDT - Q9 Arrow Right Question: Data Acquisition Queries. Questions from Sanborn 1. What are the specific horizontal and vertical accuracy thresholds (e.g., RMSE) required for the geospatial tagging of extracted features? 2. Will statistically significant ground truth assessments be an acceptable approach for species accuracy confirmation? 3. For the 3D models of trees and streetscape features, are there specific file format requirements (e.g., .OBJ, .FBX, or Revit-compatible) for integration with City systems? 4. Does the "interface" requested for accessing 3D models and high-resolution images need to be a custom-built web portal, or can it be a hosted solution provided by the vendor? 5. For trees not visible to the roadside / blocked, is the city okay with combing mobile LiDAR with aerial LiDAR/imagery datasets acquired from aircraft or UAS? 6. Will the City provide a blanket encroachment permit for data collection vehicles, or must the consultant apply for individual permits for various districts?
