This review presents comments on the August 21, 2008 submittal regarding a design alternative for
an infiltration trench at the aforementioned address.
The design alternative recommends the use of EZ-FLOW “Aggregate Bundles” in place of the
standard washed rock and geotextile materials in an approved infiltration trench.
The document presented does not provide adequate information to assess the use of the alternative
design. In order for the City to consider an alternative design the following information must be
provided:
The reason(s) why the applicant can not construct the infiltration trench per the approved
·
design.
Example projects in the area similar to this one that successfully utilized this proposed
·
product in place of the standard infiltration design.
Approval of the proposed product by other municipalities for a similar project.
·
Evidence of the long-term durability of the proposed product including measures to prevent
·
damage to the infiltration trench from live or static loads for the alternative design.
Any on-going maintenance requirements to ensure continued performance.
