If the development site involves land located in more than one municipality,
then the plan shall be reviewed by the Township and WCD to determine
if all activities, both within and without the Township, meet the
requirements of this chapter. The Township may only approve stormwater
management plans, facilities and BMPs and development activities located
within the Township, unless the Township and the other municipality(ies)
enter into an intergovernmental cooperation agreement authorizing
the Township to approve the same in the other municipality(ies).
