Aerial View of SMF, May 2004
Most of the land south of I-5 and north of Elverta Road to Sutter County is undeveloped Airport property.
• Includes some parcels in Sutter County, such as Rio Ramaza
Buffer land was acquired to ensure land use compatibility with aircraft operations (no housing), and will remain undeveloped.

FAA Can Require a Wildlife Hazard Management Plan (WHMP) If Conditions Warrant
Purpose• Describe the tools the airport will use to control and reduce the threat of airfield
incursions by hazardous wildlife and collisions between wildlife and aircraft.
Rules & Regulations Wildlife Identification & Training All of the Items in the Wildlife Hazard Assessment (WHA)
• Current strikes, control actions and observations (12 months)• Trends, abundance in habitat types, seasonal variances• Recommended action items for reducing wildlife hazards
Passive and Active Management Techniques• Wildlife Population Management• Habitat Modification• Land Use Changes

Sacramento International WHMP
First WHMP for SMF was approved in 1992.• Wildlife strikes at SMF between 1988 and 1992 averaged
19/year, but air traffic volume was much lower then.
1996: First major revision approved by FAA.
Major update began in 2005, completed 2007.
Professional Wildlife Team of Biologists• County Airport System – 3 positions• Contracted USDA – APHIS – WS – 1 position

FAA Is Focusing On the SMF Hazardous Wildlife Situation
Despite the resources deployed, FAA has determined that the SMF bird strike risk remains serious (based on reported strikes):
• Ranks #1 in FAA Western - Pacific Region• Ranks #6 in the nation • Ranks #2 in the nation for damaging strikes
SMF is currently under scrutiny by FAA, which has informed County Airport System that improvements are needed.

Hierarchy of SMF Wildlife Hazard Management
Habitat Modification and Management (Passive measure)
• Goal: reduce wildlife attraction.• Regular, ongoing maintenance of vegetation.
Harassment (Active measure)• Deter birds and mammals from returning to the airport by
making their experience unpleasant.
Removal (Active measure – always last resort)• Identify the proper measure to eliminate the individual as a
hazard from the airport.
![Page 9: Page 1 Sacramento County Airport System Wildlife Hazard Management Program Hazardous Wildlife Control at Sacramento International Airport Sacramento Environmental.](https://reader035.fdocuments.net/reader035/viewer/2022062417/551a29dc550346545e8b47ac/html5/thumbnails/9.jpg)

Habitat Modification to Reduce Wildlife Attraction to Airport
Installed 2-foot below-grade concrete barrier on new west perimeter fence & culvert grates to exclude coyotes and feral dogs
Allowed all tenant agriculture leases to expire in 2007 because FAA discourages agriculture on airport land.
• Virtually all crops attract birds because of seeds, fruit, and post-harvest crop remnants.
• Plowing, disking and siphon (flood) irrigation can induce invertebrate activity that attracts birds.
Review landscaping plans to avoid fruit-bearing trees and trees with predominantly horizontal limbs that facilitate roosting/nesting
Oppose landfills and other non-compatible land uses on or near airports
• Standing water and retention basins (defined as holding water more than 48 hours)
• Sewage and drinking water treatment plants• Lakes at housing developments

Bird-Aircraft Strike Hazard (BASH) Risk is Increasing in North America
Airports are typically located in flat, open areas needed for aircraft approach, departure zones and circling airspace.
• Such areas often include wetlands that attract birds.
Most aircraft now have just 2 engines, resulting in greater consequences from bird ingestion, as shown by US Airways Flight 1549 on January 15, 2009.
Increased population of some bird species most hazardous to aircraft. Example: Canada Goose.
Aircraft are getting quieter and faster; birds are less able to detect an approaching aircraft.
![Page 22: Page 1 Sacramento County Airport System Wildlife Hazard Management Program Hazardous Wildlife Control at Sacramento International Airport Sacramento Environmental.](https://reader035.fdocuments.net/reader035/viewer/2022062417/551a29dc550346545e8b47ac/html5/thumbnails/22.jpg)
Page 22
Increasing BASH Risk - continued
Growing dominance of low-fare airlines means more people are flying, and therefore more flights.
More wildlife refuges and preserves are being created. Many are near airports.
Wetlands are receiving greater protection because of federal Clean Water Act, which has benefited wildlife.
Banning of certain pesticides has provided protection to birds, allowing population increases.

Conclusion
Hazardous wildlife presents a clear and (now) well understood risk to the traveling public.
Consistent with our Mission Statement, the Sacramento County Airport System has implemented a comprehensive program for protecting the traveling public, and relies upon all of the tools available to us to reduce the risks associated with hazardous
wildlife. State legislation has been enacted (SB 481) to clarify in the Fish
and Game Code that airports are allowed to deploy those measures permitted under their federal fish and wildlife permit (depredation permit) issued by the United States Fish and Wildlife Service (USFWS).
