Site servicing and land development

STA 0+120What site servicing covers

A servicing job for a new subdivision, infill site or commercial pad typically bundles several disciplines under one contract or one staged program:

• Water distribution. Watermain, valves, hydrants and services to the property line, tied into an existing main at one or more points.
• Sanitary sewer. Gravity main, manholes and services, sized and graded to carry wastewater to an existing trunk or lift station.
• Storm drainage. Pipe, catch basins, and increasingly a pond or underground tank to control the rate of runoff leaving the site.
• Roads. Subgrade, base, asphalt or concrete, curb and gutter, sidewalks and street lighting conduit.
• Shallow utilities. A joint trench or separate crossings for power, gas, telecom and cable, usually built by or coordinated with the utility companies rather than the civil contractor.

Each of these is its own discipline with its own detail: see underground utilities for pipe, bedding and manhole design, and roadbuilding and paving for the road structure itself. This page covers the parts that are specific to servicing: the approvals, the levies and the order the work happens in.

STA 0+240Approvals and the servicing agreement

Before a shovel goes in the ground, the land typically needs a land-use redesignation or rezoning, a subdivision or development approval, and a servicing (or development) agreement with the municipality. The agreement sets out what the developer builds, to what standard, and what security (usually a letter of credit) the municipality holds until the work is accepted.

Every city publishes its own design guidelines and standard specifications, and they are not interchangeable. Calgary's Design Guidelines for Subdivision Servicing are the 2020 edition¹, its Standard Specifications for Road Construction are the 2021 edition², and Edmonton republished its Complete Streets Design and Construction Standards in 2025³. A design done to one city's standard rarely transfers cleanly to another, which is a common source of rework when a firm expands into a new market.

The engineering drawings for this stage are usually called a Development Site Servicing Plan (or equivalent) and are stamped by a professional engineer. See civil engineering vs civil construction for who does the design and who builds it, and the site servicing process for the approval sequence end to end.

STA 0+360Off-site levies and development charges

Off-site levies (also called development charges or a servicing agreement fee, depending on the province) recover the cost of the trunk infrastructure, arterial roads and community facilities that a new area draws on, even when the developer builds all the on-site pipe and pavement itself. Three examples from 2026 municipal schedules show how differently they are structured:

• Calgary charges eleven separate greenfield off-site levy lines (transportation, water distribution, wastewater and water treatment, stormwater, recreation, police, library, transit and emergency response). Summed, the 2026 rates work out to roughly $664,597 per hectare, with the transportation levy alone at $170,336 per hectare⁴.
• Edmonton charges an Arterial Roadway Assessment (ARA) instead of a single levy schedule; the 2026 city-wide weighted-average core rate is about $299,963 per hectare for residential land and $120,595 per hectare for industrial land, on top of a separate signal rate and, in some quadrants, a land dedication rate⁵.
• Regina sets a single greenfield development charge of about $385,585 per hectare for residential and commercial land and $128,494 per hectare for industrial-zoned land, effective January 1, 2026, plus area-specific charges in some growth areas⁶.

STA 0+480Why municipalities charge for growth

Local and regional governments own 72% of Canada's transportation and water infrastructure by replacement value⁷, and most of it is aging: Statistics Canada put the replacement value of road infrastructure at $1.63 trillion and water infrastructure at $963 billion as of the end of 2022⁷⁷. Levies are one way a city funds the trunk capacity new growth needs without raising general taxes; senior-government transfers are the other.

The federal government's Canada Housing Infrastructure Fund commits $6 billion over 10 years to water, wastewater, stormwater and solid-waste infrastructure that enables new housing, split into a $1 billion Direct Delivery stream (now closed to new applicants) and a $5 billion Provincial and Territorial Agreement stream⁸⁸⁸. The newer Build Communities Strong Fund, announced in Budget 2025, adds $51 billion over 10 years starting 2026-27 for local roads, water systems, housing and community infrastructure, including a Community stream that continues the former federal Gas Tax Fund at more than $2.5 billion a year⁹¹⁰.

None of this money flows to a developer directly. It reduces how much a municipality needs to recover through levies and property tax over time, and it is worth knowing about when a servicing agreement references a city capital project the new lots will tie into.

STA 0+600How a servicing job runs

1. Land-use and subdivision approval. Rezoning if needed, then a subdivision or development permit application.
2. Servicing agreement. Scope, standards, security and levies are set with the municipality.
3. Detailed design. A consulting engineer produces the servicing drawings and gets them approved.
4. Tender or negotiated award. The developer's civil contractor is selected; see bidding on public tenders for how public work is run, and bid, performance and payment bonds for the security involved.
5. Earthworks and rough grading. The site is cleared, stripped and graded to a rough subgrade before pipe goes in.
6. Underground construction. Watermain, sanitary and storm are installed deepest first, then shallow utilities in a joint trench.
7. Road construction. Subgrade preparation, base course, curb and gutter, then asphalt or concrete surfacing.
8. Testing and acceptance. Pressure and leakage testing on water, camera inspection on gravity sewers, compaction testing on fill and base, then a deficiency walk before the municipality accepts the work.
9. Warranty and holdback release. A maintenance bond typically runs one to two years before final acceptance and release of the last holdback; see construction holdbacks.

Frost and road bans shape the calendar as much as approvals do: underground work in the Prairies and northern Ontario usually targets summer and early fall so trenches are not fighting frozen ground, and paving is timed to avoid a spring road ban on the haul routes in.

STA 0+720What early servicing work costs

Alberta Transportation and Economic Corridors publishes the average of the three lowest bids on every item it tenders on the provincial highway system. These are highway-scale prices, not a municipal subdivision tender, but they are a useful scale reference for the line items a servicing job includes:

Curb and gutter is a good example of regional spread inside one province:

A municipal subdivision tender will price these differently again, because it carries urban traffic control, smaller and more constrained work areas, and municipal inspection and testing requirements that a rural highway job does not. The lot and subdivision servicing cost guide and the unit price index carry the full item list.

STA 0+840What to send for a price

A servicing job is priced from the approved (or draft) engineering drawings, not a sketch, because pipe sizes, grades and road cross-sections are fixed by the design. A complete brief usually includes:

• The approved or draft servicing drawings, or at minimum the parcel size, lot count and land use mix.
• A geotechnical report covering the subgrade, groundwater and any contamination concerns.
• The point of connection for water, sanitary and storm, and any offsite works the agreement requires.
• Whether levies have been assessed and paid, and what the servicing agreement already commits to.
• The staging plan, if the lots will be released in phases.
• The schedule, including any deadline tied to a builder's lot-take date or a freeze-up window.

Ask how holdback and warranty terms are structured, who carries the risk of an existing utility conflict found during construction, and whether the municipality's inspection and testing schedule is built into the contractor's program. Those answers predict most of the disputes on a servicing job.
