Stormwater Staff:
This letter serves to document conformance of the above referenced project with City of Fort Collins Low
Impact Development (LID) requirements. In particular, the project is meeting Section 3.1 of the Fort Collins
Stormwater Amendments to the Urban Drainage and Flood Control District Criteria Manual, including Section
3.1 (a)(1) requiring that no less than 50% of any newly added impervious area be treated using one or more
LID techniques and Section 3.1(a)(2) requiring that no less than 25% of all new paving use a permeable
pavement technology that is considered an LID technique.
Section 3.1(a)(1)
The project as a whole is proposing 1.104 acres of new impervious area (including the future 4000 sf
expansion). This results in a minimum required LID treatment area of 0.552 acres. The project is providing
0.384 acres of impervious area treated by pavers (directly or indirectly), and is treating 0.360 acres of
impervious areas using rain gardens. There is also a small area of roof (0.018 acres) that is being released
into a landscaped area. The total project area treated by LID techniques is 0.763 acres, which is 69.07%
of the total new impervious area.
Section 3.1(a)(2)
The project as a whole is proposing 24,404 sf of new impervious paving. This results in a minimum required
permeable paving area of 6,101 sf. The project has evaluated various areas for pavers, and has determined
that the most logical placement is along the front entry drive. The total area of permeable pavers provided
by the project is 5,765 sf, which is 23.6% of the total new paving. While this is slightly below the
minimum required, this area has been chosen due to it being the low point of the parking area, thereby
increasing the run-on areas of paving that can be treated. It also coincides with logical limits of the site,
which enhances the overall treatment provided and reduces overall maintenance in the future.
An exhibit has been provided to illustrate the topics outlined. Please feel free to contact me if you have any
questions.

Andrew Reese
