while the "2040 Strategic" are projects that may be built if additional funding becomes available. TriMet also has a page on their website discussing the future plans for their rail and bus lines. Current projects Other proposals TriMet has indicated that other extensions and improvements have been studied or discussed with Metro and cities in the region. These proposals include the following, with light rail and alternatives being considered: Extension to Forest Grove Extension to Oregon City via McLoughlin Boulevard (OR 99E) Extension to Bridgeport Village via I-205 Extension to Hillsboro via Sunset Highway (US 26) Extension to Vancouver, Washington Communities served The following cities and unincorporated communities (*) are in the TriMet service area: Aloha* Beaverton Cedar Hills* Cedar Mill* Clackamas* Cornelius Durham Estacada Forest Grove Fairview Gladstone Gresham Hillsboro Happy Valley Johnson City King City Lake Oswego Milwaukie Maywood Park Oak Grove* Oregon City Portland Rivergrove Sherwood Tigard Troutdale Tualatin West Linn Wood Village TriMet buses and commuter rail also serve Wilsonville, Oregon, which is outside the TriMet district, in order to provide connections to transit services operated by SMART in that city. A state law that went into effect on October 1, 1987, enabled communities with a population of less than 10,000 to petition to leave the TriMet district. A petition, which needed to be signed by at least 15 percent of registered voters in the affected area, must demonstrate that a community is not receiving adequate service and that TriMet's payroll tax is adversely affecting business activity for the withdrawal from the transit district to be approved. The first three areas to make use of the law and withdraw from the TriMet district, effective January 1, 1989, were Damascus, Molalla, and Wilsonville. The Boring area was removed from the TriMet District on January 1, 2013. Safety TriMet employs a transit police division to patrol its services. Officers in this division normally serve with local law enforcement agencies and are assigned terms with the transit police; this partnership with local police enables the closest available unit to respond to incidents. TriMet also partners with the Transportation Security Administration, which provides a canine unit to detect explosives and deter acts of terrorism. Riders are encouraged to alert TriMet employees using on-board intercoms or to dial 9-1-1 when witnessing crime or suspicious activity. TriMet operates over 4,000 security cameras. All TriMet vehicles became fully equipped with cameras in 2014.
