St. Andrews Park

A Shiny mobile app for residents of St. Andrews Park, Venice, Florida.

What it does

• Maps 388 property owners across 14 subdivisions
• Search owners by name, address, or subdivision
• Shows Venice city boundary and demographic facts
• Lists nearby EPA-monitored beach conditions
• Links to city services, county resources, and community documents

Data sources

• Owners — Sarasota County Property Appraiser (SCPA); updated weekly via data-raw/update_owners.R
• Subdivision boundaries — Sarasota County GIS plat layer
• Venice boundary — Sarasota County GIS municipal boundary layer
• Beaches — EPA beach monitoring data

Weekly update

source("./data-raw/update_owners.R")

Downloads fresh SCPA data, joins to stable geometry, overwrites data/owners.rds.

Geometry

Owner point locations were geocoded via Google API, manually corrected in QGIS (multi-unit buildings share a street address and required individual point placement), and saved as data-raw/addresses/owners_moved.gpkg. This file is the stable geometry source. Account numbers follow the property, so only ownership attributes need refreshing weekly.

Note: building footprints not used

Sarasota County publishes a building footprint GIS layer that could derive accurate centroids without geocoding. However the footprint layer carries only a street number (buildingid) with no street name — making a direct attribute join to SCPA records ambiguous across multiple streets. A spatial join via street centerlines would resolve this but adds complexity. Since accurate geometry already exists in owners_moved.gpkg and St. Andrews is a built-out community with no new construction, the footprint approach was deferred. It remains the right path if the app is ever extended to additional subdivisions.
