Street Assessment — Validity — New Assessment.—If a street assessment is valid, the superintendent of streets cannot he required to make another assessment.

Id. — Mandamus — Pleading — Application. — An application by contractors for street work for a mandamus to compel the superintendent of streets to make a new assessment for the work, which alleges that payment of the previous assessment was refused because of excess of work, must clearly set forth facts showing that the previous assessment was void, else the writ should be refused.

Id. — Excess of Street Work—Erroneous Plans and Specifications — Work Outside of Limits. —Street work done according to the plans and specifications in the office of the city surveyor, which call for work outside of the limits authorized by'the resolution of intention, is done without authority as to the work outside of those limits, and the contractors are not entitled to an assessment for the excess.

Id. —Location of Lot Assessed. —If the lot assessed wholly fronts upon the work done in excess of authority, it cannot he held liable for any assessment; hut if it fronts in whole or in part upon work authorized by the resolution of intention, the assessment against it will not necessarily be rendered void by the fact that the entire assessment purports to make a charge upon lots not within the limits fixed by the resolution of intention.

Id. — Segregation of Excess. — An excess of work done outside of the limits fixed by the resolution of intention will not invalidate an assessment against lots within those limits for work which was authorized by the resolution, if the cost of the work was estimated by the linear foot, so that the cost of the excess can be easily segregated from the cost of the remainder.

Id. — Excess of Work within Proper Limits — Appeal to City Council. — An assessment for street work embracing only the frontage covered by the resolution of intention, but including the expense of an excess of work done in accordance with the specifications, but not authorized by the resolution, may be corrected by appeal to the city council, and the failure to take such appeal is conclusive upon the owner as well as the contractor.

Id.—Lot Improperly Assessed — Appeal by Contractor.—If a lot improperly assessed is partly within and partly without the limits of the work authorized by the resolution of intention, it is the duty of the contractor, under section 11 of the act of March 8, 1885, to appeal to the city council to have the assessment corrected, and upon his failure to take such appeal, he is concluded, and cannot have the assessment corrected in any other mode.

Id. — Appeal by Owner. — An illegal assessment creates no lien upon the land assessed, and the owner thereof is not a person “aggrieved,” and is not required to appeal to the city council.
