Undeveloped Properties Industry Terminology
Absorption Rate
The pace at which lots or developed product derived from raw land sells or leases in a defined market over a given period; key for phasing and takedown schedules.
The absorption rate for finished lots in this submarket is 60 per year, so our land takedown should be phased over three years.|We underwrote a slower absorption rate given rising interest rates.|County staff asked for our assumptions about absorption to justify the phased subdivision plan.
Access Easement
A recorded legal right allowing passage over another property to reach a landlocked or constrained parcel.
We need an access easement over the neighbor’s driveway to reach the rear parcel.|Title shows a recorded access easement running 30 feet along the western boundary.|Without a legal access easement, the lender will not close on the land loan.
Agricultural Zoning
A zoning classification that primarily permits farming and related uses, often limiting residential density and commercial activity.
The tract is currently under agricultural zoning, so density is limited to one unit per 10 acres.|We’ll need a rezoning from agricultural to residential before subdivision.|Agricultural zoning keeps carrying costs low via preferential tax assessments.
ALTA/NSPS Land Title Survey
A high-standard boundary and improvements survey meeting national specifications, used to identify title matters affecting undeveloped land.
Order an ALTA/NSPS survey to verify boundaries, easements, and encroachments before closing.|The ALTA revealed a utility easement bisecting the buildable area.|Lenders typically require an ALTA/NSPS survey for raw land loans.
Annexation
The process of bringing unincorporated land into a city’s boundaries to obtain municipal services, zoning, and governance.
We’ll pursue annexation to access city utilities and higher densities.|Annexation will move the site into the municipal service area, enabling TIF.|The council’s annexation policy requires a concurrent development agreement.
Buildable Area
The portion of a site where structures may legally be constructed after accounting for setbacks, buffers, easements, slopes, and constraints.
After setbacks and wetlands buffers, our buildable area is only 18 acres.|The steep slopes reduce buildable area under the hillside ordinance.|We’ll optimize lot yield by maximizing the site’s buildable area.
Brownfield
Previously developed land, often industrial or commercial, where real or perceived contamination complicates reuse or redevelopment.
Because it’s a brownfield, we budgeted for remediation and a Phase II ESA.|State brownfield credits improve the land residual.|Repositioning a brownfield near the CBD can create significant entitlement arbitrage.
Buffer Zone
A required separation area, often landscaped or natural, that protects sensitive features or adjacent uses and may restrict development.
The code requires a 50-foot buffer zone along the stream corridor.|We added a landscaped buffer zone to mitigate impacts to the neighboring farm.|Environmental buffers reduce net developable area but help with approvals.
Cluster Development
A land planning technique that concentrates building on a portion of a site to preserve open space and environmental features.
We’ll use cluster development to preserve 40% open space while keeping unit count.|Cluster zoning lets us reduce lot sizes in exchange for conservation areas.|The planning board prefers cluster development near the greenway.
Comprehensive Plan
A long-range policy guide adopted by a local government that outlines goals for land use, growth, housing, transportation, and infrastructure.
The comprehensive plan designates this corridor for mixed-use nodes.|Our rezoning must be consistent with the comprehensive plan’s future land use map.|Staff cited the comprehensive plan to oppose low-density sprawl.
Conservation Easement
A voluntary legal agreement restricting development on land to protect natural resources, typically recorded in perpetuity.
Donating a conservation easement can generate tax benefits while preserving habitat.|The back 60 acres will be encumbered by a conservation easement in perpetuity.|We’ll offset impacts by purchasing credits from a conservation easement holder.
Contiguous Parcels
Parcels that share a common boundary; often necessary for assemblage and meeting zoning thresholds.
We need two contiguous parcels to reach the minimum PUD acreage.|The assemblage fails if we can’t acquire the contiguous corner lot.|Contiguous ownership helps with unified master planning.
Curb Cut Permit
Government authorization to create or modify a driveway connection between a parcel and a public roadway.
DOT denied our curb cut permit due to spacing from the signalized intersection.|We’ll consolidate two curb cuts into one for access management.|Curb cut approval is a condition precedent in the PSA.
Due Diligence
The investigation period to evaluate legal, physical, environmental, and financial aspects of land before acquisition or closing.
Our due diligence includes title, ALTA survey, Phase I ESA, and geotech borings.|We extended diligence to complete wetlands delineation and a traffic study.|The seller wants a nonrefundable deposit after due diligence.
Easement
A recorded right to use another’s land for a specific purpose (e.g., access, utilities), which can limit development.
A utility easement restricts building over the sewer line.|We’ll secure an easement for stormwater outfall across the neighbor’s land.|Title insurance excepts recorded easements from coverage.
Encumbrance
Any claim, lien, restriction, or liability attached to land that may affect title or use.
Existing encumbrances include a deed restriction and a utility easement.|We must clear tax liens and other encumbrances prior to closing.|Encumbrances reduce land value by constraining use.
Entitlement
The government approvals granting the right to develop land (zoning, site plan, subdivision, variances, etc.).
Our business plan is to obtain entitlements and sell to a vertical developer.|Entitlement risk includes rezoning, variances, and PUD approvals.|The entitlement timeline is 12–18 months depending on public hearings.
Environmental Impact Assessment (EIA)
A study that analyzes potential environmental effects of a proposed project and identifies mitigation measures.
The EIA will evaluate traffic, noise, air, and biological impacts.|Without a compliant EIA, the agency won’t issue the 404 permit.|Public comments during the EIA scoping meeting were extensive.
Exactions
Public requirements imposed on developers, such as fees, land dedications, or infrastructure improvements, as conditions of approval.
The city’s exactions include road widenings and parkland dedication.|We negotiated lower exactions by phasing improvements with absorption.|Exactions materially impact the land residual valuation.
FEMA Floodplain
Areas designated by the Federal Emergency Management Agency as subject to flooding; affects buildability and insurance.
Portions of the site fall within the FEMA 100-year floodplain.|We’ll file a LOMR to revise the FEMA floodplain after channel improvements.|Floodplain constraints reduce net developable area.
Frontage
The length of a property line that abuts a street or waterway; often regulates access and lot eligibility.
The parcel has 600 feet of frontage on the arterial roadway.|Zoning requires a minimum frontage of 80 feet per lot.|More frontage improves access and visibility for outparcels.
Geotechnical Investigation
Subsurface exploration and testing (borings, lab analysis) to assess soil, rock, groundwater, and bearing capacity for development.
Geotech borings revealed unsuitable soils requiring over-excavation.|We need a geotechnical report to design foundations and pavements.|Karst features identified in the geotech increase sitework costs.
Greenfield
Previously undeveloped land, typically agricultural or open space, with little or no existing infrastructure.
This greenfield tract has no utilities—offsite extensions will be expensive.|Greenfield development faces fewer remediation risks than brownfields.|We’re land banking greenfields near the new bypass.
Highest and Best Use (HBU)
The reasonably probable, legally permissible, physically possible, financially feasible use that yields the highest land value.
The appraisal’s HBU is suburban residential with a PUD overlay.|Changing the HBU via rezoning drives entitlement arbitrage.|We analyze HBU before setting the land offer price.
Impact Fees
Charges levied by local governments on new development to pay for public infrastructure necessitated by growth.
Impact fees for water, sewer, and roads total $18,000 per lot.|We modeled impact fee credits from the offsite trunk line we’ll construct.|Rising impact fees are suppressing lot absorption.
Ingress/Egress
Legal and physical access to and from a property, including driveway locations and permitted traffic movements.
Site plan shows primary ingress/egress on Main Street with a right-in/right-out.|We need cross-access for secondary egress onto the collector road.|DOT limited our egress movements due to traffic conflicts.
Land Assemblage
Acquiring multiple adjacent parcels to form a larger, more developable tract.
We’re assembling five parcels to create a 40-acre development site.|Holdout risk is the biggest threat to the assemblage.|Assemblage premiums must be baked into the land pro forma.
Land Banking
Strategically acquiring and holding undeveloped land for future development or sale, often ahead of infrastructure and demand.
The REIT is land banking tracts along the growth corridor.|Land banking allows us to control sites ahead of infrastructure expansion.|Carrying costs must be minimized when land banking raw acreage.
Land Residual Value
A valuation approach where land value equals project value minus all development and construction costs and required profit.
Using the land residual method, the justified land price is $85,000 per acre.|Higher exactions reduce the land residual.|We stress-tested the land residual against slower absorption.
Lien
A legal claim against a property to secure payment of a debt or obligation, affecting marketable title.
There’s a mechanic’s lien from prior fence work on the property.|All liens must be released or insured over at closing.|Tax liens can derail a land sale if not addressed early.
Lot Line Adjustment
A minor boundary change between existing lots, typically approved administratively, without creating new parcels.
We’ll pursue a lot line adjustment to square up the parcel for better yield.|A minor lot line adjustment avoids a full subdivision process.|The county requires new legal descriptions for the lot line adjustment.
Mitigation Bank
A site where environmental credits (e.g., wetlands, habitat) are created and sold to compensate for permitted impacts elsewhere.
We’ll purchase wetland credits from a mitigation bank to offset impacts.|Mitigation bank prices have doubled, impacting our sitework budget.|No nearby mitigation bank means on-site restoration may be required.
Net Developable Area (NDA)
Gross site area minus unbuildable portions (setbacks, buffers, floodplains, steep slopes, easements), used to estimate yield.
After constraints, the NDA is 24 acres out of 40 gross.|Yield analysis uses NDA to estimate lot count.|Reducing buffers increases NDA but may face public pushback.
NIMBY
“Not In My Back Yard”; local opposition to development perceived to negatively impact nearby residents.
NIMBY opposition could delay our rezoning hearings.|A robust community engagement plan can mitigate NIMBY concerns.|Expect NIMBY sentiment near the existing low-density neighborhoods.
Option Agreement
A contract granting the right, but not the obligation, to purchase land at a set price within a defined period.
We secured a 24-month option to purchase pending entitlements.|The option fee is credited to price if exercised.|Options de-risk land carry while we pursue zoning.
Outparcel
A pad site or smaller parcel fronting a larger tract or center, intended for separate sale or development.
We’ll carve out two retail outparcels along the highway frontage.|Outparcel sales help fund the backbone infrastructure.|Fast-food users are competing for the corner outparcel.
Overlay District
A zoning layer with additional standards that modify or supplement underlying zoning within a defined area.
The corridor overlay district mandates enhanced landscaping and signage.|An overlay can add design standards without changing base zoning.|We must comply with the flood overlay in addition to the PUD.
Phase I Environmental Site Assessment (Phase I ESA)
A standardized review of historical uses, records, and site inspection to identify potential environmental contamination risks.
The Phase I ESA found a recognized environmental condition from a former orchard.|Without a clean Phase I ESA, the lender won’t proceed.|Phase I recommended limited soil sampling near the old tanks.
Planned Unit Development (PUD)
A customized zoning mechanism allowing flexible design and mixed uses through a negotiated, master-planned framework.
A PUD gives us flexibility on lot sizes and mixed uses.|We’ll negotiate a PUD guidebook outlining development standards.|The city prefers a PUD to ensure cohesive master planning.
Plat/Platting
The map and legal process that subdivides land into lots, streets, and easements for recording.
We’ll submit the preliminary plat for the first 120 lots.|Final plat recording triggers utility tap fees and lot closings.|The plat shows new rights-of-way and easements.
Pro Forma
A financial model projecting costs, revenues, absorption, and returns for a land development project.
Our land pro forma includes takedown timing and interest carry.|Sensitivity analysis in the pro forma tests absorption and fee scenarios.|The lender wants to review our infrastructure pro forma in detail.
Proffers/Developer Agreement
Commitments by a developer—often negotiated—to provide improvements, fees, or conditions in exchange for approvals.
Our proffers include parkland dedication and a turn lane.|The developer agreement phases exactions with recorded plats.|We negotiated impact fee credits within the proffer package.
Right-of-Way (ROW)
Land reserved for public infrastructure like roads or utilities; may be dedicated or acquired as part of approvals.
The county requires 30 feet of additional ROW along the frontage.|We can’t place structures within the recorded ROW.|Dedication of ROW occurs at final plat.
Setback
Minimum required distance between a property line and a structure, defined by zoning or covenants.
Front setbacks are 25 feet; sides are 10 feet.|Setbacks plus easements constrain the buildable envelope.|We requested a minor setback variance for corner lots.
Soil Percolation Test (Perc Test)
A field test measuring soil absorption rates to determine suitability for septic systems.
Perc tests passed, so lots can use individual septic systems.|Poor perc results mean we need larger lots or community sewer.|The health department witnessed the perc test last week.
Subdivision
The legal process of dividing land into lots, streets, and public areas for sale or development.
Phase 1 subdivision creates 78 single-family lots.|Minor subdivision allows up to four lots administratively.|Subdivision approval is contingent on utility capacity letters.
Title Insurance
Insurance that protects against losses from defects in title, liens, or encumbrances not discovered before closing.
We’ll obtain an owner’s title policy with survey coverage.|Title insurance will insure over the old unreleased deed of trust.|The lender requires a loan policy at closing.
Transfer of Development Rights (TDR)
A zoning tool allowing development potential to be transferred from one property (sending area) to another (receiving area).
We’ll purchase TDRs to increase allowable density on the receiving site.|Selling TDRs monetizes value while preserving the sending area.|The TDR program can shift growth away from rural zones.
Urban Growth Boundary (UGB)
A regional planning line that limits expansion of urban development to contain sprawl and focus infrastructure.
The site sits outside the UGB, limiting near-term entitlements.|An expansion of the UGB could unlock our land bank.|UGB policy focuses infrastructure within designated areas.
Wetlands Delineation
Field identification and mapping of wetlands boundaries per regulatory criteria, used to determine permitting and buffers.
The delineation identified 4.2 acres of jurisdictional wetlands.|USACE accepted our wetlands delineation map last month.|Wetlands buffers will reduce our net developable area.
