Coreen's "Restore"

Our neighborhood park, Orchard Park, has been in a "great restoration" process for the past two years.  The city removed three fourths of the trees, moved the creek, put in a walking path, planted lots of shrubs and trees, and put in several rain gardens.   It has been very interesting to watch.   In the process the City had to sink two new sewer inlets.  The sewer covers they put on these inlets are of special interest.   They appear to be old, old covers that were probably removed from inlets on the eastern side of town where there has been a lot of "sewer restoration" being done for several years.
These covers were cleaned up and brought out to Orchard Park and "restored" for use.   Look at the cover very closely.   It has the seal of the City of Omaha on it.  The seal is quite interesting and filled with history and symbolism.   I can see a settler with a shovel, an indian, a deer, ducks, a river, the sun, forest, fields.   I cannot figure out what the shield (?) in the middle says or is?   Fortiter In Re means "in firm resolve".  I would love to talk to someone from the Sanitation Department to find out the history of these covers.  But I do not know anyone at the department and they probably would not want to receive such a call from a local citizen?
