Question: How long was the Nazi Party around for before Stahlecker joined it? Passage:On 1 May 1932, Stahlecker joined the Nazi Party (no. 3,219,015) as well as the SS (no. 73,041). On 29 May 1933, he was appointed deputy director of the Political Office of the Württemberg State Police. In 1934, he was appointed head of the Gestapo in the German state of Württemberg and soon assigned to the main office of the Sicherheitsdienst (SD). On 11 May 1937, he became head of the Gestapo in Breslau. After the incorporation of Austria in 1938, Stahlecker became SD chief of the Danube district (Vienna), a post he retained even after being promoted to SS-Standartenführer. In the summer of 1938, Stahlecker became Inspector of the Security Police in Austria, succeeding Gestapo chief Heinrich Müller in that position. As of 20 August 1938, Stahlecker was the formal head of the Central Agency for Jewish Emigration in Vienna, though its de facto leader was Adolf Eichmann. Differences of opinion with Reinhard Heydrich motivated Stahlecker to move to the Auswärtiges Amt (Foreign Office), after which he held posts as the commander of the Security Police and SD in the Protectorate of Bohemia and Moravia under SS-Brigadeführer Karl Hermann Frank. In mid-October 1939, Eichmann and Stahlecker decided to begin implementation of the Nisko Plan.

Question: What is the population of the city where the East Jordan Canal is heading? Passage:State Street continues north through the Crescent neighborhood, past the site of the historic Crescent Elementary School, and enters Downtown Sandy. It intersects 10600 South, which becomes State Route 151 a short distance to the west, and passes a large retail area that includes big box stores and the South Towne Mall. The street climbs a small hill to pass over the Jordan and Salt Lake Canal, then passes a cemetery and a small amount of undeveloped greenfield land near the crossing of Dry Creek before reaching a larger hill into which the East Jordan Canal is carved. At the top of this hill, the street passes west of Jordan High School and the South Towne Expo Center before intersecting 9400 South (former State Route 209). A short distance north of that intersection, the East Jordan Canal passes back under the street on its way toward Holladay, and Rio Tinto Stadium fronts onto the street on the west side. Just before the intersection with 9000 South (modern State Route 209), State Street passes the site of a former smelter (which now has a medical center built on part of it). The street forms the western boundary of the Sandy Historic District from 9000 South to Pioneer Avenue (8530 South), and several historic buildings face onto it in this area. There is a traffic signal it the intersection with Sandy's Main Street at 8720 South. North of the historic district, State Street passes through some relatively lightly developed land near the city's border with Midvale, though there are some townhouse developments in progress in the area.
