SECTION 1 - STATEMENT OF WORK

Request for Proposal

Project/Service Summary

The Spokane International Airport is soliciting proposals for

The Airport invites experienced and qualified landscaping maintenance companies with at

least five years of experience including but not limited to lawn care and edging, leaf control

and removal, weed control including annual pre and post emergent applications, shrub and

bush trimming, shaping, tree pruning, irrigation service and repair, seasonal plantings and

plant replacement at the SIA, Tech Park, and ABP, as listed in Attachment A. Each location

has a distinctive and unique aspect of landscape maintenance. Attachment A and its

Appendix’s have a description, frequency and level of landscape maintenance expected by

the Airport and Exhibits A, B and C for each location covered by this Request for Proposal.

Budget and Funding Source(s)

The anticipated costs for this project/service are: The not-to-exceed budget is $300,000.00

for the 9-month contract term.

Grant and/or Federal funds will not be used for the work under this RFP.

Schedule (post award)

Contract for a term of nine (9) months beginning on March 1, 2026, and ending November

30, 2026, with four (4) nine-month term options, at the sole discretion of the Airport.

Firm fixed price for services in Attachment A – Scope of Work and firm fixed hourly price for

other services as requested by the Airport.

Project/Service Location

All work is to be performed at various locations of SIA, Tech Park, and ABP. See Section 6 for

Exhibit A, B And C.

Goals

 Maintain a neat, attractive, and safe airport landscape across SIA, Tech Park, and ABP

covering lawns, trees, shrubs, groundcover, planter beds, roadsides, islands, swales, and

parking‑adjacent areas so vegetation is healthy, uniform, and unobstructive.

 Deliver reliable, scheduled maintenance (weekly mowing, seasonal fertilization, irrigation

monitoring/repairs, pruning, weed control, pest/disease control, litter/debris removal)

aligned with best horticultural practices.

 Ensure irrigation systems operate optimally proper coverage, seasonal

turn‑on/winterization, prompt adjustment/repair minimizing overspray, staining, and water

waste. Maintain Spokane City ‘Water Wise’ regulations.

Landscape Maintenance

RFP #26-40-9999-003

Request for Proposal

 Provide responsive coordination and quality oversight via monthly onsite inspections with

Airport reps, accurate records (work calendars, product use), and two‑workday correction

windows for deficiencies.

 Protect airport users and assets. Keep vegetation off roadways/curbs, maintain clear

drainage in swales and storm drains, and handle chemicals safely by licensed applicators.

Unique Considerations/ Challenging Requirements

 Active airport environment & public visibility: Work in high‑profile areas (terminals, garages,

rental car lots, parking lots, and inbound/outbound roads, demands immaculate

appearance and minimal disruption.

 Security boundaries: No access to restricted areas. Plan operations are entirely within

non‑badged zones.

 Tight service windows: Mowing for SIA and Tech Park must be completed within one day

(requested Tuesday), ABP mowing within one day (requested Wednesday), with irrigation

checks the following day (SIA Wednesday; ABP Thursday). Weather may force schedule

adjustments while preserving overall turf quality.

 Site‑specific bagging rules: Terminal at SIA and Tech Park weekly bagging; ABP requires

bagging every other week except Buildings 1200, 1100, 1378 (weekly). This affects crew time

and disposal logistics.

 Roadway & parking‑lot pruning standards: Branches must not extend into roadways or over

curbs; trees near vehicles may need extra insect control and coordination to avoid

overspray/drip onto cars. Tree suckers shall be removed and maintained. Shrubs shall not

overhang on to sidewalks.

 Drainage and swales: Keep swales and storm drains cleared; certain edges and rock bedding

areas require sterilization treatments and hand/mechanical weed control.

 Chemical stewardship: WA‑licensed applicators, manufacturer‑label compliance, dormant

sprays timed pre‑bud, documentation (MDS, application logs).

 Deficiency correction clause: Two workdays to remedy after written notice; costs of

third‑party corrective work deducted from payment if not resolved—requires robust QA and

rapid response. Written notices include email and text.

 Square footage verification: Actual areas must be field‑verified, influencing material rates

and labor planning.

 Weather variability: Fertilizer windows and herbicide applications are weather‑dependent

(e.g., no pre‑emergent in frozen soil); mowing heights and schedules may shift with

conditions.
