This cache forms part of my Village Signs series around Chelmsford. Other caches in the series are:
VS#861 Great Baddow
VS#867 Little Baddow
Collect information in these caches to locate the final cache in the series: VS#869 Chelmsford
The cache is not at the sign but can be found a short walk away.
In order to find the cache, apply the following offsets to the listing coordinates:
Northings: Nearby are two speed limit signs, one for each direction. Add these speed limits together and add them to the northings.
Eastings: How many layers of brick are used in the plinth? Take this number from the eastings.
The log contains a number which will help you find VS#869 Chelmsford. Don't forget to take a note of it!
