Stevens & Permanente Creek Survey
February 18, 2017

With the significant wet environment early in the year, it was decided that Mountain View ARES-RACES should make this drill a review of the high water points along Stevens Creek and Permanente Creek in Mountain View. This melds both Ham radio skills and CERT assessment skills to achieve better results and mutual understanding.

The goal was to deploy radio operators in cars with mobile radios and observers to visit each designated stream observation point and report the status of the creek to net control at K6MTV. It was also suggested that pictures should be taken at each survey point looking up stream and down stream. This turned out to be a very good idea as you will see from the pictures. Since Mountain View ARES works closely with Mountain View CERT, it was suggested to invite Mountain View CERT members to ride along.

Objectives

• Confirm that our stream survey locations/instructions are correct

• Check on both mobile and HT simplex coverage to the stream survey sites

• Clarify if both upstream and downstream observation is possible and any related issues

• Identify any real time issues at any site.

Stevens Creek – Downed tree

This section was added to show a downed tree across Stevens Creek which could eventually flow out to the bay causing a potential hazard to marine traffic. This must be removed soon before it does any damage. Location coordinates: 37.397267, -122.067969.

The bank erosion photos are shown here to demonstrate that creek maintenance must be done before any more significant damage is done to the creek. Location coordinates: 37.400997, -122.069139
