Economic Impact Group · LOCI® — Residential

New rooftops bring revenue.
They also bring a bill.

A development adds households, students, trips and calls for service on the same day it adds tax digest. LOCI® — Residential runs both sides of that ledger — new property, sales and other revenue against the marginal cost of serving what actually gets built — year by year, for thirty years, on your community's own digest and its adopted budget.

The problem

Most fiscal impact studies a board sees arrive with per-capita averages standing in for real service costs, stabilized values standing in for a phase-in, and no separation at all between what a new household actually triggers and what the budget was going to fund anyway. A commissioner who cannot rebuild that number is voting on a brochure. LOCI® — Residential was built to end that.

How it works

Three inputs. One fiscal verdict.

The community is described once. After that every project is a few minutes of input — and the answer comes back on your digest, your millage and your adopted budget, not on a rule of thumb borrowed from someone else's county.

Layer 01

Describe the community

Population, households, the tax digest, millage by fund and the adopted budget as your jurisdiction actually reports them. County or city, incorporated or unincorporated, with or without a city school system.

Digest · millage by fund · adopted budget

Layer 02

Program the development

Every use, phased by year — single-family, townhome, apartments by tier, age-restricted, plus retail, restaurant, lodging, office and industrial — with values, absorption, construction years and any incentive on its own schedule.

Residential · commercial · phasing

Layer 03

Read the verdict

Revenue above the line, cost of service beneath it, net impact and net present value year by year — with the general government and the school district carried as two separate ledgers, and a report you can hand a commissioner.

Capabilities

Everything a rezoning hearing will throw at the number.

Revenue, cost of service, the school district and the density assumptions underneath them — all from the same inputs, so no two exhibits can quietly disagree.

Net fiscal impact

Does the development carry its own weight?

Drag absorption, values or the mix and the whole thirty-year schedule re-runs. Revenue and cost of service move together, and the model returns the net impact and its present value — the number a commissioner will ask for first and challenge hardest.

The school ledger

Where most projects turn

School revenue and per-student cost run on their own ledger, because the district is usually the body that decides whether the project is a net positive at all.

Cost of service

Marginal, not per-capita

Public safety, general government, public works and recreation each carry their own density factor — so the model prices what the next household actually triggers, not the county's average spend divided by its population.

Horizon

Thirty years, discounted to today

Construction ends. Absorption finishes. Values appreciate and service costs follow. The model runs the full thirty years and reports it as net present value, with the phase-in window drawn in.

Stress testing

Which assumption is carrying it?

Unit values, student yield, absorption and density factors move independently — so when the projection is one optimistic assumption away from turning negative, the model says so before the staff report goes out.

Under the hood

No black box.

Every dollar in the projection traces back to a millage rate, a budget line or an assessed value. Open any year of the schedule and follow the number home.

01

Your digest, not a national average

Millage by fund, the assessment ratio and local exemptions as your tax commissioner actually reports them — because 400 homes do very different things in two counties with different digests.

02

Marginal cost, not average cost

The model prices what an additional household actually costs to serve, with density factors for general government, public safety, public works and recreation you set yourself rather than a flat per-capita divide.

03

Schools carried on their own ledger

The school district has its own millage, its own revenue and its own cost per student. It gets its own ledger — because it usually decides whether a project is a net positive at all.

04

Absorption separated from appreciation

Construction years, phase-in and value growth are three different assumptions, so you can see which one is carrying the forecast and stress each on its own.

05

Where the workers live and spend

Jobs by land use, the share of employees who live in the jurisdiction and local capture of retail spending drive the income and sales tax lines — not a blanket multiplier applied to everything.

06

Incentives modelled, never assumed

Abatement schedules and public support run on their own thirty-year track, so the net-of-incentive number always sits next to the gross one instead of replacing it.
