Why Irrigation and Hardscaping Proposals Are Different

Landscaping proposals for mowing, planting, or lighting follow a relatively predictable format. Irrigation and hardscaping proposals don't — they require calculations that other trades can skip.

Irrigation pricing depends on the number of zones, the type of heads, the water pressure available, and whether you're designing a new system or retrofitting an existing one. A 6-zone system with fixed spray heads has a completely different cost structure than a 12-zone system with gear-drive rotors on a slope. Your proposal needs to show the client the math behind your numbers.

Hardscaping pricing depends on base preparation — and that's where most contractors get into trouble. "Per square foot" pricing without base depth specifications leads to disputes when the client discovers that your "$12/sq ft" doesn't include the geotextile fabric, edge restraint, or drainage layer. Every square foot number in your proposal needs a corresponding base spec.

Key insight: Irrigation proposals are sold on zone design and head specs. Hardscaping proposals are sold on base depth and drainage. Get those details in the proposal and clients stop shopping you on price — they can't compare $12/sq ft vs $14/sq ft when they understand that your base spec includes 6 inches of compacted Class II AB and theirs doesn't.

What an Irrigation Proposal Template Must Include

Every irrigation proposal — new installation, retrofit, or repair — needs these sections:

Irrigation Proposal Checklist

Zone breakdown — List every zone with head type (rotor, spray, drip), quantity, and precipitation rate in inches per hour. Each zone is its own pricing line.
Head specifications — Brand, model, and nozzle. "Hunter PGP rotor" is not a specification. "Hunter PGP Ultra 4-inch pop-up, 12A nozzle, 100 psi working pressure" is. Include gallon per minute per zone for water audit tracking.
Pipe layout and mainline sizing — Note mainline diameter (typically 1 inch for residential, 1.5–2 inch for commercial), lateral pipe size, and installation method (trench vs. direct bury).
Controller and smart features — Controller type, number of stations, Wi-Fi or smart features, and monthly weather-based adjustment. Even if it's a basic controller, list it — it has a price and it matters to clients.
Backflow prevention — Required by code in most municipalities. Specify the backflow preventer type (PVB or DCVA), size, and whether it's included in the base proposal or a separate permit item.
Pump or booster system — If the site needs a booster pump for low pressure, spec it separately. Pump systems add $1,500–$4,500 to a job and need their own electrical line item.
Material and labor per zone — Show head cost, pipe cost, and installation labor per zone. Add zone subtotals and a grand total. Clients trust what they can verify.
Winterization service — Blow-out service as a separate optional line item. Many clients don't know this is required in cold climates — it's a value-add to include it in the proposal as a recommended add-on.
Signature line and valid-until date — Signed acceptance, start date estimate, and valid-for-30-days clause. Include any pre-work conditions (site marked by utilities, etc).

Sample Line-Item Pricing: 6-Zone Irrigation System ($7,450)

Here's what a properly structured irrigation proposal looks like for a 6-zone residential new installation. These 2026 figures cover a typical 1/3-acre lot with average water pressure.

Zone Head Type Amount
Zone 1 — Front Lawn (8 rotors) Hunter PGP Ultra 4" pop-up, 12A nozzle, 25 ft radius $1,180
Zone 2 — Side Lawn (6 rotors) Hunter PGP Ultra 4" pop-up, 8A nozzle, 18 ft radius $920
Zone 3 — Back Lawn (10 rotors) Hunter PGP Ultra 4" pop-up, 15A nozzle, 30 ft radius $1,450
Zone 4 — Front Shrubs (12 spray heads) Hunter Pro-Spray 4" with HE-VAN nozzle, 15 ft radius $680
Zone 5 — Back Shrubs (8 spray heads) Hunter Pro-Spray 4" with HE-VAN nozzle, 15 ft radius $480
Zone 6 — Drip Line (flower beds) 1/2" drip tubing, pressure compensating emitters, 50 ft runs $340
Mainline & Laterals 1" SCH 40 mainline, 3/4" laterals, swing joints, fittings $1,100
Controller Hunter Hydrawise Pro-HC 12-station, Wi-Fi, weather-based scheduling $520
Backflow Preventer 1" PVB, Watts 007, required for city permit $380
Total 6-zone new installation, parts and labor, permit-ready $7,450
Pro Tip

Always show drip as its own zone — never bundle drip into spray zones. Drip operates at 30–60 PSI with different flow rates than spray heads. Putting drip on the same valve as spray heads means either the drip gets too much pressure or the spray heads don't pop up at all.

What a Hardscaping Proposal Template Must Include

Hardscaping proposals cover a range of work: paver patios, natural stone walkways, retaining walls, seat walls, outdoor kitchens, and water features. The core structure is the same for all of them:

Hardscaping Proposal Checklist

Base material type and depth — Class II AB at 4–6 inches for residential patios, 6–8 inches for driveways, 8–10 inches for heavy vehicle areas. Specify the material and compaction standard (95% or 98% Modified Proctor).
Bedding layer — 1 inch of concrete sand on top of base. This is not optional — it's what allows the pavers to be leveled and sand-set properly.
Paver material with pattern — Manufacturer, product line, color, and finish. List the sq ft cost separately from installation. "Roman cobble" is not a specification — "Unilock Roman Cobble, Sierra color, 3-7/8 × 7-3/4 × 2-3/8 inch, running bond pattern" is.
Edge restraints — Either plastic edge restraint (for soft edges) or concrete mow strip (for edges against soil or turf). Specify which and why. Never skip edge restraint — it's the most common cause of paver edge shifting within 2–3 years.
Drainage provisions — French drain at low points, channel drain at doors, swale grading, or geotextile fabric. Show these as separate line items, not bundled into "site prep."
Compaction and subgrade prep — Show subgrade laser grading, mechanical plate compaction of base (minimum 2 passes), and sand screeding as separate steps. Compaction is not included in excavation — it's its own line item.
Retaining wall specs — Block type, wall height, setback batter, geogrid reinforcement (if wall is over 24 inches), drain pipe and clean rock behind wall. Retaining walls need engineering for walls over 4 feet — include this as a separate line if required.
Cleanup and disposal — Demo material hauling, site cleanup, and final grading as separate line items. Clients get upset when they find out "the job" doesn't include hauling away the old concrete they asked you to demo.
Signature line and valid-until date — Signed acceptance, scope of work boundaries, and valid-for-30-days clause. Include photo documentation if working around existing landscape elements.

Sample Line-Item Pricing: 400 Sq Ft Paver Patio ($14,750)

Here's a properly structured hardscaping proposal for a 20 × 20 ft paver patio with concrete-edge restraints, French drain, and geotextile fabric on clay soil.

Line Item Description Amount
Demolition & Excavation Demo existing concrete pad, remove and haul away, excavate to 10" depth, laser-grade subgrade to 1.5% slope away from house $1,850
Geotextile Fabric Mirafi 500X geotextile over clay subgrade to prevent base migration $320
Class II AB Base (6") 6" compacted Class II aggregate base, mechanical plate compaction (2 passes minimum, 98% Modified Proctor) $2,200
Concrete Sand Bedding (1") 1" washed concrete sand, laser-screeded to final grade $580
Paver Material (400 sq ft) Unilock Town Hall II, Sierra blend, 3-15/16 × 7-3/4 × 2-3/8 inch, running bond pattern — material only, including 10% overage $3,200
Paver Installation Cut and set all pavers, install edge restraints (2 × 4 treated mow strip, rebar pins at 24" O.C.), joint sand and compact $3,600
Edge Restraints 6" × 6" concrete mow strip at all landscape edges, #4 rebar at 24" intervals $920
French Drain (Zone 1) 4" ADS perf pipe, wrapped in sock, 12" × 12" clean rock trench, outlet to daylight at slope low point $880
Polymeric Sand Techniseal HP NextGel joint sand,湿润 and seal per manufacturer specs $420
Final Grading & Cleanup Backfill edges with topsoil, fine grade, seed or sod as needed, haul all debris $780
Total 400 sq ft paver patio — base, bedding, pavers, drainage, restraints $14,750
Pro Tip

Add 10% overage on paver material — every job cuts at least a few pavers to fit curves, borders, or angles. Clients rarely complain when you return unused material at the end. They absolutely complain when you run 5 short and need to order more, delaying the job and going over budget.

Common Irrigation & Hardscaping Proposal Mistakes

1. Not breaking irrigation into per-zone pricing

"Complete irrigation system — $8,000" tells the client nothing. If they want to add a zone or downgrade a head type, you have no leverage. Zone-by-zone pricing lets you negotiate scope without repricing the whole job from scratch.

2. Skipping drainage in a hardscaping proposal

Drainage is the one thing that determines whether a paver patio lasts 5 years or 25 years. If you don't spec it, the client won't budget for it, and they'll be furious when the patio puddles after the first rain. Always include a drainage line — even if it's "no additional drainage required (slope provided)."

3. Not specifying base depth on hardscape

"6 inches of base" is not a specification. "6 inches of compacted Class II AB, compacted to 98% Modified Proctor, mechanical plate compactor" is. Without the compaction spec, a client who gets 3 inches of loose base will blame you. With the spec, you have a documented standard to hold your subs to.

4. No overage calculation on paver material

Every paver job cuts some pavers. If you price material at exactly the square footage with no overage, you'll run short. Price with 10% overage and note it in the proposal — clients understand why.

5. Forgetting the winterization line item

In cold climates, irrigation systems must be winterized with compressed air blow-out. Many residential clients don't know this is required. Including it as a recommended add-on in the proposal means you either capture that revenue ($150–$350 per system) or the client knows it's coming and schedules it with you rather than calling a competitor.

Scale-up opportunity: Irrigation and hardscaping often go together on the same property — new landscape means new irrigation, and new hardscape means the irrigation zones need redesign to avoid watering pavers and walls. When you're on site for one, always propose the other. The client is already committed to the project; bundling the bid is easier for them and easier for you.

Frequently Asked Questions

What should an irrigation proposal include?
An irrigation proposal must include: a zone-by-zone breakdown showing head type, spacing, and precipitation rate per zone; pipe layout and mainline sizing; controller type and programming schedule; backflow prevention device specs; material and labor costs shown per zone with a subtotal; pump or booster system if required; any winterization service as a separate line item. The proposal should specify the irrigation head brand and model, not just "sprinkler heads."
What should a hardscaping proposal include?
A hardscaping proposal needs: base material type and depth (typically 4–6 inches of class II road base for pavers); bedding sand layer; paver or slab material with pattern and sq ft cost; edge restraints; drainage provisions (French drain, channel drain, or swale); any retaining wall specs (block type, wall height, geogrid reinforcement if over 24 inches); compaction and subgrade prep as separate line items; and cleanup or disposal as its own line. Never quote a paver job as a lump sum per square foot without specifying base depth.
How do you price irrigation systems per zone?
Price irrigation per zone by calculating: number of heads × head cost + manifold/valve cost + pipe and fittings cost + trenching and installation labor. For a typical 8-head residential zone: $80–$120 per head for gear-drive rotors or MP rotators, $45–$80 per valve (solenoid valve), $2–$4 per linear foot for 1-inch lateral pipe, $15–$25 per head for installation labor. A complete 6-zone system with controller typically runs $4,500–$9,000 depending on head type and whether it's a new install or retrofit.
What is the right base depth for a paver patio?
Standard paver patio base is 4–6 inches of compacted Class II AB on native soil, plus 1 inch of concrete sand bedding, plus the paver height. Total excavation depth is 7–10 inches below finished grade. For clay soil or areas with poor drainage, increase base to 8 inches. For heavy vehicle loads (fire lane, driveway), use 8–10 inches of base with geotextile fabric between native soil and base material. Always include geotextile fabric in your base proposal for clay soil — it prevents base migration and keeps the installation from settling.
How do you handle drainage in a hardscaping proposal?
Drainage is often the line item that makes or breaks a hardscape installation over time. For surface drainage: swale grading at 1–2% slope away from structures. For subsurface drainage: French drain (4-inch perforated ADS pipe in rock trench) at low points, draining to daylight or a dry well. For edge drains along retaining walls: weep holes or footer drains. For pool decks or areas with heavy water: channel drain (ACO or NDS) at doors and transitions. Price drainage as a separate line item so clients see exactly what they're getting.
