Various Tree Work

1. two dead trees on grass verge outside No 21 need to be replaced with similar. 2. self seeded trees/bushes outside No 16 have caused a small wall to collapse onto the highway and are not allowing water to drain. 3. trees removed outside No 15 & 20 never replaced ! is this happening ? 4. growth at the base of a conifer outside verge of No 16 was cut back a few years ago & needs doing again as it is on a bend with limited visibility.
