Why isn't LA repaving streets?

📝 Discussion Summary (Click to expand)

Five key themes that dominate the discussion

# Theme Representative quotes
1 Budget constraints & corruption in city infrastructure “What the city can’t seem to do is rid itself of corrupt employees and corrupt practices.” – themafia
“The city’s budget is all going to police and police liability payouts.” – skrtskrt
“The city can’t afford to replace just the ramp sections.” – scoofy
2 ADA compliance costs vs. perceived benefits “I don’t think there’s a way to do this without casting something to connect the pre‑fab to the surrounding concrete sidewalk.” – AlexandrB
“The idea is to provide a tactile warning that the street is nearby for people with vision impairments.” – nonameiguess
“ADA ramps are expensive, $50k per corner.” – bradlys
3 Construction methods: prefabricated vs. cast‑in‑place “Maybe they'd settle badly if vehicles drive over them.” – georgefrowny
“Prefabs you first dig up both road and sidewalk.” – lstodd
“The challenge is properly anchoring them into the surrounding soil.” – mschuster91
4 Vehicle weight and road wear debate “Road wear is a power law, and heavy trucks cause the wear.” – gscott
“SUVs cause more damage.” – kev009
“Heavy trucks cause the lion’s share of road damage.” – bubblewand
5 Housing density & tax base as a solution to infrastructure deficits “California cities could trivially fix their budget problems by satisfying the demand for housing by adding density.” – scoofy
“Prop 13 freezes taxes.” – bradchris
“Increasing density would help pay for infrastructure.” – scoofy

These five themes capture the bulk of the conversation: the struggle to fund and manage city infrastructure, the cost‑benefit calculus of ADA ramps, the technical debate over curb‑cut construction, the impact of vehicle weight on road wear, and the broader policy discussion about density and tax revenue.


🚀 Project Ideas

CurbRamp Connect

Summary

  • A city‑centric mobile/web app that lets residents report curb‑cut and sidewalk issues, tracks work orders, and visualizes project status on a map.
  • Provides real‑time updates, budget visibility, and a feedback loop between citizens and municipal departments.

Details

Key Value
Target Audience City residents, city public‑works departments, local NGOs
Core Feature Issue reporting, GIS‑based task tracking, budget dashboards
Tech Stack React Native / Next.js, Mapbox GL, PostgreSQL/PostGIS, Node.js API, Firebase Auth
Difficulty Medium
Monetization Revenue‑ready: subscription per city (tiered by population)

Notes

  • HN commenters lament the slow, opaque process of curb‑cut installation (“3 months to build 12 ramps”). This tool would give them a clear timeline and cost estimate.
  • The platform could spark discussion on how to prioritize projects and allocate limited funds, and could be used by other municipalities facing similar bottlenecks.

RampForge

Summary

  • A cloud‑based CAD and ordering system that lets city planners design curb cuts that fit existing geometry, generate manufacturing specs, and place orders with prefabricated ramp suppliers.
  • Automates compliance checks against ADA and local regulations.

Details

Key Value
Target Audience City engineers, public‑works planners, construction firms
Core Feature Parametric curb‑cut design, auto‑generation of BOMs, regulatory validation
Tech Stack WebGL, Three.js, AutoCAD API, Python backend, AWS Lambda, Stripe
Difficulty High
Monetization Revenue‑ready: per‑design fee + subscription for updates

Notes

  • Users like “prefabricated kerb ramps” and “cutting through cast‑in‑place kerbs” want a tool that removes the guesswork. “Prefabs are quick but hard to fit” – RampForge solves that.
  • The system could become a standard for municipalities, reducing installation time from weeks to days.

Predictive Pavement Planner

Summary

  • A data‑analytics platform that ingests traffic, weather, and maintenance logs to forecast when and where sidewalks and curb cuts will need repair, and estimates associated costs.
  • Enables proactive budgeting and capital‑project planning.

Details

Key Value
Target Audience City finance & planning departments, infrastructure managers
Core Feature Predictive modeling, cost‑projection dashboards, scenario simulation
Tech Stack Python (pandas, scikit‑learn), PostgreSQL, Grafana, Docker
Difficulty Medium
Monetization Revenue‑ready: SaaS per city (annual license)

Notes

  • HN users complain about “budget cuts” and “unfunded mandates.” This tool gives them data to argue for the right amount of funding.
  • It could be a hot topic for discussions on how cities should allocate scarce resources and whether predictive maintenance can save billions.

ModuRamp Kit

Summary

  • A modular, on‑site installation kit that allows contractors to quickly assemble prefabricated curb cuts with minimal excavation and anchoring.
  • Includes standardized connectors, hydraulic jacking adapters, and a quick‑install guide.

Details

Key Value
Target Audience Construction contractors, city public‑works crews
Core Feature Rapid assembly, minimal site disruption, hydraulic jacking integration
Tech Stack Mechanical design (SolidWorks), 3D printing prototypes, CNC machining
Difficulty Medium
Monetization Revenue‑ready: per‑kit sale + service contract

Notes

  • “Prefabs are quick but hard to fit” – the kit solves the fit problem with modular connectors. “Hydraulic slab jacking” is integrated for settlement correction.
  • Contractors and city officials would discuss the trade‑off between upfront kit cost vs. long‑term labor savings.

CityContractor Hub

Summary

  • A B2B marketplace that connects city departments with vetted contractors, provides pre‑approved bids, ensures ADA compliance, and tracks performance metrics.
  • Includes a compliance engine that flags regulatory gaps before work begins.

Details

Key Value
Target Audience City procurement offices, construction firms, compliance auditors
Core Feature Bid management, compliance validation, performance analytics
Tech Stack Ruby on Rails, PostgreSQL, AWS S3, OAuth, API integrations with city ERP
Difficulty High
Monetization Revenue‑ready: transaction fee + subscription for premium analytics

Notes

  • HN commenters mention “corruption” and “inefficiency” in city contracting. This platform would bring transparency and reduce the risk of over‑billing.
  • The discussion could focus on how to balance open procurement with the need for specialized expertise in ADA‑compliant construction.
