GC Allocation with new array length

I'm using a mesh generator script and it creates vertex and normal arrays inside update because we're growing the mesh dynamically during runtime. So, we're using something like this: vertexArray = new Vector3[segments.Count * segmentVerts.Length]; And same for normal array.
Because the segment length increases through out the game (for a couple of minutes), the gc alloc goes upto 50kb and we see spikes regularly. I tried using List , adding values and then converting it back to array because the Mesh class accepts vertices, normals and uvs as arrays but that just made gc alloc heap worse. Does anyone have any suggestions for this issue?
