Dear Ms. Ross,
In 2012 St. Croix Valley Landscaping (SCVL) built seventeen Lake Elmo raingardens. The one year
maintenance warranty period began November 14, 2012 and ends November 14, 2013 (See attached
bid). Now that spring is here I wanted to follow up on what needs to be complete in order to receive
final approval and payment.
(1.) 2013 maintenance must be addressed per the August 29th, 2012 estimate provided by SCVL. The
following items will need to be completed as necessary to maintain all raingardens:
Provide maintenance twice yearly. Weeding and cleaning inlets including haul away of debris
and adding preen.
Watering. Water raingardens assuming use of city water supply through fire hydrants not to
exceed 5 times.
Mulch installed. Top dress mulch 1” with delivery.
Suggested timing for the above maintenance tasks is to first visit raingardens in May to weed and clean
inlets if not earlier. The second visit recommended for weeding and cleaning inlets is early July. Mulch
can be added at the second visit in July. We recommend watering take place on an as needed basis in
between rain events. Watering will be highly important for July through August adding an inch per week
if there is no rain forecasted.
Please give me a 48 hour notice each time you plan to visit the 2012 Lake Elmo raingardens. I will be
inspecting each visit. For scheduling purposes, please send me estimated dates SCVL will be performing
the above maintenance.
(2.) A one-year warranty walk-through will need to be scheduled to identify any defective work or
issues related to the construction of the raingardens. In August 2013 I will schedule a time with
SCVL to walk through the project and develop a list of corrective items as necessary. Once the
maintenance items have been completed and all one-year warranty corrective items addressed, I
will write a recommendation for final approval and payment to the City of Lake Elmo.
Please let me know if you have any questions.
Sincerely,
Tara Kline
