This is a form published by BCDC at the RAPC meeting on June 3. Fill it out and send it to me. I'll forward it to them.For now, just use the number system they define. Contact Neuwirth directly if you have any questions. I've just made their stuff into a web page.

This is a tool to understand the impacts of various proposed airfield developments on San Francisco Bay. The development scenarios described below are the sets of runway proposals currently being modeled for their ability to safely meet the region’s projected flight demand through 2020. Most of these runway alternatives require Bay fill. Although the detailed environmental assessment of these proposals is just beginning, this scorecard is a simple method of judging the impacts of individual runway proposals and their cumulative effects. As projects are refined and environmental documents are made public, this scorecard can be completed by scaling the duration and extent of impacts on Bay resources. The matrix proposes a 1 to 4 ranking scheme. The table lists the resources vertically and the scenarios horizontally. These resources are the considerations required by the law governing BCDC. We hope it provides a useful perspective. Please let us know how we can help you understand these important issues. Thank you.

SCENARIOS

The following scenarios are the Regional Airport Planning Committee’s primary runway alternatives being studied for airspace and runway capacity.

Scenario 1

This alternative assumes no additional runways at San Francisco International Airport (SFO) or Metropolitan Oakland International Airport (OAK). At San Jose International Airport (SJC), it considers two 11,000 ft. air carrier runways with 700 feet of separation as described in their Master Plan. This is their level of development for all scenarios. No Bay fill is contemplated at SJC.

Scenario 2a

This scenario analyzes the Refined BX Alternative at SFO and no new runways at OAK. Refined BX would construct a new 9,000 ft. runway 4,300 feet northeast of existing Runway 10L/28R to allow two aircraft to land simultaneously during inclement weather conditions, and would convert existing Runway 28L for use predominantly as a taxiway. This proposal would also extend existing Runway 1R/19L 7,500 ft. to the northeast, convert runway 1L/19R to use as a taxiway, and construct a new 9,000 ft. Runway 1R 3,400 feet to the southeast of extended Runway 1R/19L. Other minor runway modifications and additional facilities are also contemplated. Depending on the construction technique, the surface area of bay fill is estimated to be between 730 and 1,222 acres.

Scenario 2b

Scenario 2b considers no new runways at OAK with the F2 Alternative at SFO. F2 would construct a new runway 4,300 feet northeast of existing Runway 10L/28R to allow two aircraft to land simultaneously during all inclement weather conditions, and would convert existing Runway 28L to use predominantly as a taxiway. It would also extend existing Runways 1R/19L by 5,000 feet to the northeast, convert runway 1L/19R for use as a taxiway and construct a new 11,500 ft. runway 4,300 feet northwest of existing Runway 1R/19L. Other airfield improvements are included in this proposal. Between 789 and 1,332 acres of Bay fill could be required depending on which construction methods are employed.

Scenario 3

This alternative proposes new runways at both SFO and OAK. The runway at OAK would be inboard of the current runways but would not require Bay fill. At SFO, Alternative 3A would be analyzed. This would construct a new 11,500 ft. runway 4,300 feet northeast of the existing Runway 28R to permit two aircraft to land simultaneously during inclement weather conditions and would convert existing Runway 28L/10R predominantly to a taxiway. Other runway improvements and supporting facilities would also be constructed. The estimated Bay fill of the new runway is between 403 and 605 acres depending on construction techniques.

Scenario 4a

This scenario analyzes SFO’s Refined BX with the new inboard OAK runway as described above.

Scenario 4b

Scenario 4b combines SFO’s Alternative F2 with OAK’s new inboard runway as described above.

Scenario 5

This scenario analyzes no new runways at SFO with a new outboard runway (B3) at OAK. The new runway at OAK would be 4,300 foot into the Bay parallel to Runway 11/29. This proposal would fill 462 acres of the Bay and create an enclosed lagoon of 543 acres.

Scenario 6a

Scenario 6a analyzes SFO’s alternative Refined BX with OAK’s B3 as described above.

Scenario 6b

This scenario analyzes SFO’s alternative F2 with OAK’s B3 as described above.
