Narrative:

I am a flight instructor at laf. The lack of appropriate airport signage and taxiway markings at one of its major taxiway intersection is a recurring source of confusion for pilots who are unfamiliar with the airport. The taxiway C/B intersection lacks signage. Taxiing north on B from runway 10/28 or northwest on B 3 from runway 5/23; there is no signage pointing to taxiway C. Both of these taxiways are popular exit points from runway 10/28 and runway 5/23.that same intersection lacks appropriate taxiway pavement markings. There is no taxiway centerline that connects taxiway south/southwest-bound to taxiway B3 or taxiway B. The centerline only connects taxiway C so that it takes aircraft northeast on taxiway B. This centerline design seems to make unfamiliar pilots think that such turns are unauthorized; which leads them to (correctly) question their taxi instructions with the ground controller. Airport operations designed the taxiway centerline at this intersection in a way that suggests no aircraft would need to turn southwest onto taxiway B from taxiway C; west onto taxiway C from B; or west onto taxiway C from taxiway B3. This is a significant oversight; since most of laf's traffic consists of single-engine VFR aircraft; who exit taxiway 23 at B3 or exit taxiway 28 on B. Almost all non-tenant aircraft intend to taxi to the FBO on the airport; which is located off of taxiway C. Therefore; the aforementioned turns at this intersection are used on a daily basis.nearly all of the confusion could be eliminated if the airport installed a sign at this intersection to clearly define the location of taxiway C. [A sign is already available but they lack the cement block necessary to install it.] given how frequent pilot confusion occurs at this intersection; the airport administration needs to put this on a higher priority level.I noticed upon closer examination that this taxiway intersection is unmarked from all sides. Therefore; not only can pilots taxiing north on taxiway B or taxiway B3 not easily locate taxiway C; but neither can aircraft taxiing south on taxiway B who need to turn right on taxiway C. Additionally; when taxiing east on taxiway C; there is no signage pointing to taxiway B whatsoever.the fact that this intersection is so close to two runways makes me fear that the mis-marked intersection has the potential to negatively impact safety. Taxiing east on taxiway C; pilots could accidentally continue straight ahead onto runway 23 if they are waiting to find a sign pointing to taxiway B. Alternatively; if their runway assignment is runway 5; and they need to get there via taxiway C and taxiway B; they could turn left on taxiway B in accordance with the only painted line at that intersection; creating a nose-to-nose situation with aircraft taxiing south on taxiway B to runway 5.
