do not oppose - no significant negative impact upon highway safety, network functionality and/or parking as the accesses and layout are acceptable
no objection
no objection subject to condition - preliminary assessment of bats is all in order. Mitigation was not considered required but bat boxes would be welcomed. As bats are known to utilise the area external lighting should be controlled. No nesting birds found at site but can't be ruled out and so two bird nest boxes also sought
