An investigation into the Sacramento development department’s approval of building permits in a flood zone will be considered by the City Council on Tuesday. City Attorney Eileen Teichert and a third party-law firm, Renee Sloan Holtzman Sakai, have been investigating the Community Development Department’s decision last year to greenlight 35 building permits in a Natomas area regulated by the Federal Emergency Management Agency. At the Tuesday meeting, the city attorney’s office will make a presentation on the investigation. Teichert’s office acknowledged in a Dec. 15 letter to the FEMA office in Oakland that the city broke federal rules by authorizing the permits. Councilman Steve Cohn
