It is helpful to discuss potential building changes (such as installing water-efficient plumbing fixtures) early in the negotiations so that the base building team has time to adjust and implement the necessary changes by the time the CI project is completed. 

If the tenant will occupy a significant portion of the building for a minimum of ten years, consider working with building management to encourage implementation of green strategies that will help your project meet LEED requirements in areas beyond the tenant’s control. Look especially at the credits in the Sustainable Sites section. For example, the project team could suggest:

With a longer lease term, it’s important to select your building location very carefully. If you don’t choose a LEED-certified building, try to find a building with improvement opportunities that have payback periods within the lease term. Use the thresholds outlined in the LEED credits, especially those in the energy section, as a framework for determining the cost implications of potential improvements.  

With longer leases, occupants benefit from energy and water savings and other efficiencies over a longer period of time, which can mean greater incentives to implement green strategies with longer payback periods. Examples include: 

lighting system upgrades 
daylighting controls 
improved wall assemblies and windows 
improved air delivery equipment 
heat and energy recovery systems.  

If your project is a renovation, and the tenant is halfway through a ten-year or longer lease, you can still comply—there is no stipulation that the lease has to start at the beginning of construction. 

Include with your credit documentation a detailed narrative explaining the tenant's intent to stay for ten years or longer.

Tenant and owner meet during lease negotiations before a project begins to discuss an extended lease, with a minimum of ten years.

To earn the credit, the tenant must commit to remaining in the same location for at least 10 years. The most straightforward way to do this is through an extended lease.

Implement an ongoing stormwater system maintenance plan with the landscape manager. This should include a regular schedule for monitoring the performance of the stormwater management system and guidelines for repairing or modifying site features that are causing problems. These guidelines could include replacing or increasing vegetation, redirecting runoff, and increasing storage.   

After completion of all construction activities, document credit compliance in LEED Online by uploading these documents: 

A narrative that declares the standard followed (2003 EPA CGP or local). If you used a local standard, write a narrative report detailing how it is equal to or more stringent than the CPG (Phases I and II, NPDES program). 
A written ESC plan or project drawings showing the control measures used.
Proof of implementation with one of the following: an inspection report with the required signature, nine photos, or a narrative report.
