Green infrastructure is very effective and cost efficient, but in order to provide adequate financing, innovative models are needed to capture its benefits, especially since green infrastructure is often implemented at the landscape level and in multiple distributed projects, as opposed to the conventional grey infrastructure that might consist of a single large project like a dam or a floodwall. Green financing structures should also be fair and incentivize the distributed implementation of green infrastructure on a variety of property types.
In 2015, the HB1325 passed the state legislature, which authorizes counties to charge a “user fee” for creating and maintaining stormwater management systems and infrastructure – a stormwater fee. As of 2018, the City & County of Honolulu has not taken advantage of this authority yet.
The Ala Wai Watershed Collaboration has partnered with the Environment & Climate Change team at Baker McKenzie to explore which green finance tools might be appropriate to help support ongoing and future work in the Ala Wai Watershed.
