Descriptiontext

The City of San Dimas is an incorporated municipal government operating under California general law in Los Angeles County, serving residents and businesses within its city limits. The city delivers core municipal services through dedicated departments covering Administrative Services (Finance, Human Resources), City Manager's Office (City Clerk, Economic Development, Public Information, Transportation), Community Development (Building and Safety, Code Compliance, Housing, Parking Enforcement, Planning), Public Works (Engineering, Environmental Services, Street Maintenance, Utilities & Franchises, Solid Waste, Traffic Services), and Parks & Recreation (Parks & Trails, Recreation and Sports, Senior Services, Facility Rentals, Fitness, Historic Sites, Special Events). Public safety is delivered in coordination with the Los Angeles County Sheriff's Department and the San Dimas Fire Department.

The city's core technology stack is a web-based municipal service platform hosted at sandimasca.gov, supplemented by a Citizen Request App and integrated third-party SaaS providers: HDL Companies operates the business license portal (sandimas.hdlgov.com), rec1 powers recreation program registration, PayMyCite handles parking citation payments, Rave Mobile Safety delivers emergency notifications, PlanetBids manages bids and RFPs, and Castus.tv streams City Council meetings on YouTube. No AI/ML capabilities are disclosed; the platform is conventional web technology with GIS mapping and online records library functionality. Notable digital services include online bill pay, public records request center, GIS maps, an online records library for legislative and administrative documents, and a 2026 Resident Guide published in flipbook format.

The city is funded through diversified municipal revenue streams: property taxes (recurring), sales tax on commercial transactions (transaction-based), business license and permit fees (annual/licenses), and utility franchise fees collected from electricity, gas, water, communications, and solid waste providers operating within city limits. The GTM motion is direct-to-consumer municipal service delivery through City Hall walk-in service (Monday–Thursday 7:30 am–5:30 pm, Friday 7:30 am–4:30 pm), online self-service portals, and department-specific service centers including a Senior Citizen/Community Center. The city is governed by a directly elected Mayor serving two-year terms and four by-district Councilmembers serving staggered four-year terms, with no term limits.
