The provisions of this chapter, which are a substantial reenactment of provisions of a prior ordinance, shall be constructed as a continuation of such provisions, modified or amended according to the language employed, and not as new enactments. The repeal by this chapter of any other ordinance or part thereof shall not affect or impair any act done, offense committed or right accruing, accrued or acquired or liability or penalty, forfeiture or punishment incurred prior to the time such repeal takes effect, but the same may be enjoyed, asserted, enforced, prosecuted or inflicted as fully and to the same extent as if each such repeal had not been effected.
