Project Description

RainRoots Consulting has been contracted by NAU to complete an inventory of the NAU mountain campus to determine the optimal locations for low impact stormwater management systems to increase stormwater retention, increase groundwater recharge, and decrease the impacts of flooding on downstream infrastructure.


Potential locations will be scored using a decision matrix based on field visits and watershed analysis.


Plan set documents will be drafted for the top designs and an analysis of existing versus proposed stormwater impacts will be completed.

Project Constraints

Existing Landscaping and Infrastructure

At our clients request, and in order to maintain a low impact, the chosen LID implementation locations cannot require extensive changes to existing landscaping or infrastructure.

Aesthetics

The client has requested locations that have minimal impact to campus aesthetics. This includes avoiding major pedways, new landscaping, and the historic north quad.

Cost

The client has requested stormwater solutions that can be implemented at low cost. This means that smaller locations that are easy to access for construction and maintenance will be prioritized. As well as those that don't require the construction of an underdrain.

LID Design

Bioswales and detention basins have physical requirements for feasibility. This includes things such as slope and soil type. Because  of this, a large section of central campus will not be considered due to steep slopes.
