LPV's are actually built to a TCH. If the airport has an ILS installed,
they'll aim for the same TCH. If they don't have ILS, they'll select a
TCH based on the wheel height group, which is based on the type of
aircraft expected at the runway. Wheel height groups can be found at the
following link, on page 19 of 70. The smaller the aircraft, the lower
the TCH requirement, which would make the touchdown point closer to the
threshold.

give an idea of runway lengths required. 3058' doesn't meet the criteria
for LPV, so to answer your question, no LPV (unless criteria changes).

My question. I'm assuming the LPV approach would target 1000ft down
the runway as the TDZ (just like an ILS). Does this mean that LPV
approaches will not be added to the airports with smaller runways?
For example, my homefield (3ck)has a 3058 runway. The 1000 ft TDZ
would only leave 2000 ft to get stopped, so I am wondering if an LPV
approach would ever be added at 3ck (or similar airports).
