The Secretary of the Commonwealth shall examine the application and statement and, if he finds that the name proposed for the district is not identical to that of any other soil and water conservation district shall receive and file them and shall record the application in an appropriate book of record in his office. If the Secretary of the Commonwealth finds that the name proposed for the district is identical to that of any other soil and water conservation district, or so nearly similar as to lead to confusion and uncertainty, he shall certify such fact to the Board, which shall submit to the Secretary of the Commonwealth a new name for the district. Upon receipt of the new name, the Secretary of the Commonwealth shall record the application, with the name so modified, in an appropriate book of record in his office. When the application and statement have been made, filed and recorded, as herein provided, the district shall constitute a political subdivision of the Commonwealth. The Secretary of the Commonwealth shall make and issue to the directors a certificate, under the lesser seal of the Commonwealth, of the due organization of the district and shall record the certificate with the application and statement. The boundaries of the district shall include the territory as determined by the Board, but shall not include any area included within the boundaries of another district, except in those cases otherwise provided for in this article. The name of any district may be changed if a petition for such change is subscribed by twenty-five or more landowners from each county or city comprising the district and adopted by resolution of the district directors at any regular meeting. The district directors shall submit a copy of the resolution to the Board and, if the Board concurs, it shall present the resolution, together with a certified statement that it concurs, to the Secretary of the Commonwealth who shall file the resolution and issue a new or amended certificate of organization.
