Tree and Infrastructure Inventory and Analysis

2026-11-03

1 . Tree Inventory Update & Location Mapping : Review and update the current tree inventory ( approximately 120 , 000 ) by adding new assets and removing those that no longer exist . All data collected shall be recorded in a format compatible with the City ’ s existing inventory dataset and that dataset ’ s attendant geographical unique identification ( GUID ). All care should be taken to preserve points in the dataset , along with the attendant GUIDs , when the asset that is symbolized is not in the same exact position as the point . The point should be moved rather than creating a new GUID or point . The contractor is expected to ensure data accuracy , consistency , and completeness throughout the assessment process . 2 . Infrastructure Inventory : Optionally extract and export infrastructure inventory from the collected LiDAR data of the following types . ● City Street Trees ○ Canopy extent and clearance over roadway / sidewalk ○ Connection to existing inventory assets ● Signs ( Traffic , Regulatory , Informational , and Wayfinding ) ● Traffic Control Signals ( traffic signals , traffic lights , turn arrows , pedestrian signals , countdown timers , push - buttons , accessible pedestrian signals , bicycling signals , school zone signals , etc .) ● Poles and Vertical Support Structures ( Light , Utility , and Communication Poles ) ○ “ Cobra ”/“ Historic ” typing , if available . ● Fire Hydrants ○ Cap Color , if available ● Buildings and Structures ( buildings , park pavilions , shelters , restroom facilities , maintenance buildings , kiosks and small structures , permanent canopies and covered structures ) ○ Footprints and Heights ● Street and Park Amenities ( benches , trash cans , bicycle racks , bus shelters , kiosks etc .) ● Traffic Calming and Vehicle Blocking Devices ( speed humps , cushions , speed tables , raised crosswalks , raised intersections , rumble strips , traffic circles , medians , bollards , planters used as barriers ) ● Above - Ground Utility Cabinets and Enclosures ● Sidewalks and Sidewalk Appurtenances e . g . ramps , curbs , crossings , etc . ○ Cross slope , running slope , and more characteristics of sidewalks and sidewalk appurtenances are desired , if available ● Street condition ○ Provide location of man holes , particularly when not “ in plane ” with the street ○ Note : street location , size , and centerline data sets not needed . For all infrastructure types , please provide a definition of data that can be extracted and pricing along with any options that can be used to expand or limit cost . Alternatively , please provide cost of or access to download of raw LiDAR point cloud data . 3 . Tree Attribute & Condition Assessment : Record the following data for each tree : ● Common Name ● Diameter at breast height ( DBH ) in inches ● Overall condition assessment ○ Dead , Critical , Poor , Fair , Good , Very Good , Excellent ● Identify defects or observations ● In Forest Park , record crown width ( in inches or feet ), height ( in inches or feet ), and scientific name Record the following information for each stump : ● Diameter ( in place of DBH )...
