4. Nexus Studies and Fee Structuring

Public agencies commission nexus studies to establish legally defensible fees

Nexus process

Establish maximum defensible fee ceilings; Develop standard fee schedules by land use - Residential (Single vs. Multi-Family), Non-Residential (Commercial, Industrial); ….and for different infra category - Transportation, Water/sewage, Parks/open space, Fire/safety, Affordable housing; Question - Could maximum ceiling impede new developments?; Refine/finalize fee schedules and legislate DIF program

Ultimate fee decisions driven by funding priorities and DIF effect on new development feasibility based on local real estate market

Designing DIF Fee Structure—Basic Components

Define Service Area - Establish Level of Service Standards - Fee Types/Amounts - Payment Timing

Defining Service Areas and LOS Standards

Define Service Area

Geographic-specific impact fees for variations in infra costs and project impacts:

  • Existing infrastructure capacity (infill vs. Greenfield)
  • Proximity to public transit
  • Availability of other funding sources

Establish LOS Standards

Most State DIF statutes allow full local authority in setting LOS standards

  • Generally, same LOS standards for all
  • LOS standards can vary based on local
    growth/land use policy, development
    patterns/constraints

Setting Standard Fees and Payment Schedule

Standard fee schedules for each service area based on LOS stds

  • Fees for each infra category and each land use within category
  • Based on incremental infra costs to accommodate new trips
  • Residential: No. trips/dwelling unit (DU) for single vs. multi-family
  • Non-residential: No. trips/1,000 sq. ft. for office, retail, industrial
  • Inter-jurisdictional fees for regional impacts, share resources

Payment Timing

When fees are imposed (assessed) and when they are collected

  • Timing of building permit vs. certificate of occupancy (CO)
  • Significant lag between the two and many variations
