A C.V. of my past experience relative to dams and infrastructure

Scott P. Cahill


I have directly managed or supervised many hundreds of millions of dollars of work across the United States over the past forty-five years, including constructing and repairing dams, bridges, airports, petrochemical and chemical plants and buildings, water and wastewater treatment plants, electrical sub-stations, large industrial plants, docks and water-based construction, and pipeline pump stations. I have constructed earthen, concrete, and stone dams and have completed repairs to hundreds of dams. I am the Director of Watershed Services, Inc. which has specialized in water-related construction (both underwater and above), including dam repair and maintenance and related consulting services for the past eighteen years.

I have been directly involved in issues of dam and infrastructure safety throughout the United States, participating in the training of dam owners and dam safety officials at many events and conferences including state-wide, regional, and national. Topics have included construction, means and methods, safety, and training for many organizations, as well as politics and physics.

I am nationally-recognized as an expert in the repair and construction of infrastructure, including dams and heavy civil structures. I have been interviewed on national and local news stories about dams throughout the United States. Media regularly solicits my comments on issues of infrastructure and dam safety. I have assisted in drafting dam regulation and legislation, and have authored white papers on infrastructure maintenance. My blogs have readership as high as 400,000 per piece, covering issues of infrastructure, physics, and politics (See LinkedIn and ScottCahill.org).

Including testifying before the Virginia House of Delegates Subcommittee on Agriculture, Chesapeake, and Natural Resources and the Virginia Senate Subcommittee on Agriculture, Conservation, and Natural Resources. I was the sole person selected to represent the construction and engineering community before these committees. Also included advocating for the changes directly with certain state Congressmen.

Formed and managed the Technical Advisory Committee for the Salem Downtown initiative, organized committees and chaired committees, coordinated, drafted, and wrote the plan (Seventy-seven page detailed recommendations including regulation and legislation), and oversaw its implementation to renovate a failed downtown and bring occupancy of the downtown from seven percent of occupiable space to near seventy percent in five years, coached businesses and incubated twenty five new or moved businesses into downtown Salem (my home town).

Development of Real Estate

Sovereign Building, downtown Richmond, Virginia – purchased, renovated, and sold downtown building (mid 1990s)

Sandy Feet, Topsail Island, Surf City, N.C.  Development with nine oceanfront townhomes and P.O.A. (1995)

Half a city block purchased and renovated, occupied and sold (four buildings), Salem, Ohio. Sold and financed. (2012-15)

Courtyard Square, seven adjoining Turn of the Century buildings historically renovated into a mixed-use development with interior mall. All buildings renovated, leased and occupied (35,000 sf) Twenty-five new businesses were formed, incubated, or moved to this mall. Twenty-three remain operational in the downtown.

Save Downtown Salem Downtown Revitalization Effort – Technical Advisory Committee organized, formed, and managed to transform a failing downtown. I formed the Salem Downtown TAC, organized it into committees, drafted a report and submitted it to the city council, lobbied for the implementation of the recommendations, and successfully transformed a downtown with seven percent occupancy into a vibrant community of restaurants and shops.

Commercial Diver Supervisor Supplied Air Diver (helmet diver supervisor) I held this license from the Assoc. of Diving Contractors International. – lapsed, not renewed. S.C.U.B.A. license issued in 1965 by the YMCA. It was issued but did not become effective until I reached the age of thirteen, two years from its issuance. I was one of the early divers, starting at ten years old, and have, since completed thousands of dives. PADI certification also.

Mueller Report

It is not the AG’s job to protect the president. It is also not an AG’s job to protect those executing a coup. The witch hunt which we were assured would result in the impeachment of the president under the 25th amendment ended without action by Mueller. His story in the second part of the report has no precedence nor bearing. No investigation offers vindication of any who are investigated, only an indictment or not. Mueller was armed with falsehoods paid for by Hillary and the DNC. He was pushed on by a group of traitors at the uppermost level of the FBI who arranged, disseminated and lied about this false information’s origin to persuade a FISA court to execute a warrant. With that warrant they then spied on an active campaign and subsequently a cabinet of our President. If these assertions are accurate, no amount of flamboyant writing on the part of Mueller, no statement on behalf of the frustrated candidate or President can alter the situation, which is a situation of intent to subvert a duly elected official of the United States, its President. If these assertions are correct these actions are treasonous. (Via Google “nounthe crime of betraying one’s country, especially by attempting to kill the sovereign or overthrow the government…synonyms: treachery, lese-majesty; Morethe action of betraying someone or something.plural noun: treasons) Two illegalities occurred one was an act off treason in an effort to dislodge our sitting President, the second was an act of leaking classified information to press and public to distort the perception of this President to the same end.
