A dependable Lynnwood landscape proposal maps drainage, grades, soil, irrigation, retained vegetation, access and material movement before choosing finishes. The City of Lynnwood publishes residential permit checklists, while Washington L&I provides contractor verification. Give bidders the same drawing, quantities and establishment expectations so the comparison reflects real scope rather than different assumptions.
Require existing and proposed conditions, access and staging, drainage paths, soil preparation, irrigation tests, plant quantities and sizes, hardscape base details, permit and utility responsibilities, establishment care, cleanup and measurable closeout. Separate allowances and exclusions before comparing totals.
Record property boundaries, easements, utilities, grades, downspouts, low areas, mature trees, retained features and access widths. Identify what can be disturbed and what must be protected. When buried systems or root zones are uncertain, state the investigation method and assumptions. A measured base plan prevents crews from solving layout conflicts after excavation begins.
Observe roof discharge, surface flow, ponding and where water leaves the property. Define proposed slopes, inlets, cleanouts and lawful discharge points. New lawn, mulch or hardscape should not conceal a wet area or redirect runoff toward a building or neighbor. If connections or grading need review, identify the responsible designer, permit applicant and inspection point.
Compaction, texture, rooting depth and organic matter influence drainage and establishment. State whether existing soil is retained, loosened, amended or removed, with areas and quantities. Avoid a generic amendment line that does not explain depth or placement. The planting plan should connect exposure, water delivery and mature plant size to the prepared root zone.
Document controller condition, valves, pressure, leaks, heads or emitters, coverage and overspray. Define repairs, new zones, sleeves, backflow responsibility and final programming. Planting and irrigation must use compatible hydrozones. A controller that powers on does not prove the system delivers appropriate water to each root zone without runoff.
Patios, paths and retaining features need excavation limits, subgrade condition, base material, compaction, drainage, edge restraint and finished elevations. List dimensions and layers rather than one installed-area figure. Assign transitions, stairs, rails, lighting and adjacent restoration. Structural or trade elements may require review beyond ordinary planting work.
Narrow gates, occupied drives, slopes and protected beds change equipment and labor. State delivery points, staging, haul routes, tree protection, temporary erosion control and restoration. Separate removal of sod, soil, concrete, roots and old irrigation because each has different loading and disposal. Access assumptions should be visible before totals are compared.
Lynnwood's residential permit materials help define when building review may be part of a project. Landscaping can also intersect with utilities, right-of-way, drainage, walls, electrical and plumbing. Confirm the actual scope with the responsible authority, locate utilities before excavation and verify construction contractors through Washington L&I. Name each licensed participant in the agreement.
State watering, mulch, staking, pruning, weed control, correction duties and the duration of establishment care. At walkthrough, check drainage paths, irrigation coverage, hardscape stability, plant quantities and cleanup. Collect plans, controller settings, product and plant schedules, buried-component photos, maintenance instructions and warranty terms. A landscape is complete when its systems function, not only when installation day ends.
Describe the project once and we match it with vetted local pros who actually do this work — you choose who to hire, or nobody at all.
The city's development services materials identify permit documentation for residential work.
The state lookup includes registration, bond and insurance information.

| Decision | Weak version | Decision-ready version |
|---|---|---|
| Drainage | Improve as needed | Grades, inlets, outlets and discharge path shown |
| Soil | Amend beds | Condition, depth, material and quantities stated |
| Irrigation | Repair system | Pressure, zones, coverage and controller checks listed |
| Plants | Landscape allowance | Species, size, quantity, spacing and substitution rules |
| Establishment | Warranty included | Watering, maintenance, correction period and duties named |
Separate demolition, earthwork, drainage, soil, irrigation, hardscape, planting, establishment, disposal and restoration. Use measured quantities and decision rules rather than unsupported local averages.
Access, earthwork, drainage, material handling, irrigation, hardscape base work and establishment care are major drivers.
Yes. Document grades, inlets, outlets and discharge paths before new surfaces conceal the problem.
Check pressure, leaks, zones, coverage, controller operation and overspray under actual operating conditions.
Walls, drainage, right-of-way, electrical, plumbing or structural work can require review; confirm the actual scope.
Use species, size, quantity, spacing, location and substitution rules plus establishment responsibilities.
Subgrade, base, compaction, drainage and edge restraint determine stability beyond the visible surface.
Verify drainage, irrigation, hardscape and plant quantities, then collect plans, settings, photos and warranties.
Normalize quantities, preparation, access, disposal, establishment and exclusions before comparing totals.
Share the property, problem areas, desired uses and timing. We can connect you with contractors prepared to explain drainage, soil and establishment scope.
