Draft EA - San Diego International Airport

SAN DIEGO INTERNATIONAL AIRPORT – PROPOSED RUNWAY 9 DISPLACED THRESHOLD
subject to fog and/or reduced visibility conditions (less than 3 statute miles) 2.83 percent of the time. 1
Loss of
the CAT I instrument approach to Runway 9 for Category D aircraft would prohibit operations on Runway 9
during reduced visibility or inclement weather conditions, causing delays and financial losses to the airlines,
passengers, and companies relying on travel and/or the shipment of goods via SDIA.
2.3 Alternatives Retained for Analysis and Identification of the
Proposed Action
Based on the evaluation of alternatives, two alternatives were retained for evaluation in this EA:
No Action alternative
300-foot Relocated Runway 9 Displaced Threshold alternative
Of these two alternatives, only the alternative to relocate the Runway 9 displaced threshold by 300 feet meets
the purpose and need identified in Chapter 1; thus, this alternative was identified as the Proposed Action.
Although the No Action alternative would not meet the stated purpose and need for the Proposed Action, it
was retained for analysis in this EA to comply with Title 40 CFR 1502.14(d) and FAA Order 1050.1E, which
requires consideration of the No Action alternative. Thus, only the No Action and Proposed Action
alternatives are analyzed in detail in this EA.
2.4 Sponsor’s Preferred Alternative
Based on the criteria noted above, the Sponsor selected the Proposed Action identified in Section 1.5 as its
Preferred Alternative. The Proposed Action meets the Purpose and Need, limits the reduction of landing
runway length and has a lesser project cost.
2.5 Federal Laws and Regulations Considered
In accordance with FAA Order 1050.1E, Paragraph 405(d)(4), the relevant federal laws and statutes, executive
orders, and other federal regulations considered during preparation of this EA are listed in Table 2-1,
Table 2-2, and Table 2-3, respectively.
