MEMORANDUM

TO: Mayor Jones and Members of the Board FROM: Karen Proctor, Town Administrator DATE: May 2, 2019 RE: Preliminary Gate Design Discussion

DISCUSSION:

On March 29, 2019 the Board received copies of the preliminary gate plans for the Richfield and

Fremont gates and was asked to provide any comments or concerns. Discussion was held at the

April 18, 2019 Board meeting regarding the designs and SEH was asked to provide an

alternative design for the Fremont Gate.

Attached as Exhibit A are drawings from SEH of the three gate designs (2 for Fremont and 1 for

Richfield), along with the corresponding probable construction cost estimates of each gate

design and the gate specifications. Staff has talked with the traffic committee and believes that

$50,000 for each “gate system” may be high. However, we cannot determine the actual cost

until bids are received based on the specifications the Town is requesting.

The Board must choose which location to move forward with for the Fremont gate and approve

the preliminary designs. Once that is done, SEH will begin Task 2 which is the final design

documents. Task 2 is expected to take 2-4 weeks and following the completion of Task 2 the

RFP will be completed and put out for companies to bid on the project.
