What if we don't need a new church plant?

In 2016, Pastor Charlie Cotherman led the planting of Oil City Vineyard Church just upriver from us in Oil City.  I know Charlie, and God has blessed his vision for Oil City with a church that is thriving.  That same year, Pastor Joseph Gibson led the planting of Cranberry Community Church (Assemblies of God) a few miles 'uphill' from us in Cranberry.  I know Joseph as well, and God has also blessed his vision for Cranberry with a church that is thriving.  Planting a new church is often seen as a way of waking up a community, of bringing something new and potentially exciting to the mix, and ultimately (hopefully) of tapping into the work of the Spirit and reaping a harvest for the Kingdom.
But what if a village, town, or other relatively small community already has more churches than average?  What if that town has quite a bit more than one would expect to find for a town its size? {More than it needs?  Is that a real thing?}  The town of Franklin has just over 6,000 people (it was 6,500 in 2010, this year's census will provide new numbers), and with that population, contains 1 Catholic, 3 Church of God, 1 American Baptist (that's us), 1 Nazarene, 2 United Methodist, 1 Free Methodist, 1 Wesleyan Methodist, 1 Christian Missionary Alliance, 1 Presbyterian, 1 United Brethren, 1 Episcopal, 1 Lutheran, 1 Pentecostal, and 1 Foursquare.  In addition, across the river in Rocky Grove we have another United Methodist church, another Church of God, another Presbyterian church, and a Pilgrim Holiness church; I can think of another 7 churches within three miles of town (4 UMC, 2 Independent Baptists, 1 Community).  If we add in Rocky Grove, that's 20 (27 in a 4 mile radius) churches for a population of about 7,000.  If everyone in town went to church each Sunday, we'd each have about 350 people.  There are 3 churches with that number or more, but most have between 50-125.  In theory we could fit all 7,000 people in our church pews, maybe needing a few 2nd services.  {That's with 100% attendance, those who are home-bound take several hundred off of that potential group, but at a very healthy 50% attendance rate, we'd still have more than enough church pew space}.  With a population that has been in steady decline since the 1970's, and a number of churches that still reflects the glory days of the Oil Boom (when my church regularly had over 1,000 people on Sundays, and others were packed too), it would seem illogical to consider adding another church to Franklin's already massive and diverse repertoire.
Oil City didn't suffer from a lack of churches when Charlie and his family arrived, although it seems that he filled a niche that may have been underutilized.  The same seems true with Joseph and Cranberry, given its smaller population than either Franklin or Oil City, but also the lack of any church in our area associated with the Assemblies of God (the one in Franklin closed several years ago).  How do we know if God's purpose would be better served by focusing our energy and vitality on reviving that which is already here, or trying to build something from scratch?  The Book of Acts in the New Testament doesn't offer us any direction as to how many churches should exist in any particular community, so we're not going to find easy answers.
There are a lot of under-served communities in America, and tens of thousands of them worldwide.  These are places with one church per 10,000 people, and even far worse ratios.  Compared to them, Franklin is overly, abundantly, blessed, as is our county as a whole {with about 50k people and well over 100 churches}.  If God has plans to send us someone like Charlie or Joseph (and their wives and kids), I'll welcome them with open arms, but if God's plan is instead to work with what we already have here, I've no doubt that we can get the job done with the churches (both the communities and the buildings) we already have serving this community.
