有关LIM 上有一条 Limited Drainage

平静中期待

LIM 上有一条有关土地使用的，很多就是 Main Residential. 但是这个房的LIM 上除了 Main Residential, 还有 Limited Drainage.
有人知道是什么意思吗？

Information relating to the use to which the land may be put and any conditions attached to that use

LIMITED DRAINAGE

MAIN RESIDENTIAL

还有一条有关 crosslease 的 Resource consents

There may be conditions at this resouce consent that require compliance before the commencement of the use, or on an ongoing basis.

一般会是什么 condition 呢？
