Opinion delivered March 31, 1924.

1. Municipal corporations — improvement districts — unity.—The statutes relating to the organization of municipal improvement districts contemplate that each improvement shall constitute a single project, and that wholly disconnected improvements cannot be joined in one district.

2. Municipal corporations — conclusiveness of decision of council. — The determination of a city council in including property in an improvement ■ district as to the singleness and unity of the improvement project, as well as the selection of the property to be benefited thereby, is conclusive except for fraud or demonstrable mistake.

S. Municipal corporations, — unity of improvement. — An ordinance creating a paving district which grouped together streets connected by means of other streets already improved through the agency of 'other paving' districts, *held*not invalid on its face ■ for lack of unity in the proposed improvement.

Appeal from Mississippi Chancery Court; *J. M. Futrell,*Chancellor;

affirmed.

*Max B. Reid,*for appellants.

The paving district is void because the portions of streets to be improved are so widely scattered that they cannot constitute a single district. The map exhibited with the complaint, as well as the evidence, discloses the fact that the district is not a district *locality,*but a series 'of special groups or separated portions of streets to toe improved. Constitution, art. 19, § 27; 52 Ark. 107; 39 Sí WV 660; 84 Ark. 257.

*313*Frank M. Douglas, Bose, Hemingway, Cantrell & Loughborough,*for appellees.

1. It is settled by tbe decisions of this court (1), that property adjoining tlie locality to be affected is any property adjoining or near the improvement which is physically affected, or the value of which is commercially affected, directly by the improvement, in some degree in excess of the effect upon the property in the city generally; and (2), that the action of the city council, in including property in an improvement district is conclusive of the fact that it is adjoining the locality to be affected, except when attacked for fraud or demonstrable mistake. 126 Ark. 172; 5'2 Ark. 107; 70 Ark. 451; 84 Ark. 257.

2. It is no longer open to question that the system of streets in question constitutes a single improvement. 150 Ark. 127; 135 Ark. 524; 125 Ark. 325; 137 Ark. 354; 139 Ark. 595; 138 Ark. 549; 142 Ark. 552; 144 Ark. 46.

McCulloch, C. J.

Appellees are the commissioners of a street paving district, designated as Paving District No. 2 of Blytheville, Arkansas, organized under the general statutes (Crawford & Moses’ Digest, § 5647 *et seq.)*for the purpose of paving certain designated streets; and appellants are the owners of real property within the boundaries of the district, which embraces the whole of the city of Blytheville. There are several streets and parts of streets to be paved through the agency of this district, and some of them are not connected with each other. It appears, however, from the plats and other portions of the record that all of the streets to be paved are connected together by other streets improved in like manner through the agency of other districts. It appears from the plat and from other portions of the record that all of the streets in a large portion of the city of Blythe-ville, including practically all of the business part of the city, have been paved through the agency of another district, and that the streets to be paved in the district now under consideration, though disconnected from each other, are connected up with the other paved streets, and, *314when all of the improvements are completed, it will constitute a solid area of paved streets in the city.

Appellants instituted this action in the chancery court against appellees to restrain the proceedings on the sole ground that the organization of the district is void (quoting from the complaint) “because the portions of streets to be improved are so widely scattered that they cannot constitute a single district. ’ ’ The validity of the ordinance is not assailed in any other respect, and the question of the amount or validity of the assessment of benefits is not involved. In other words, it is conceded that all of the statutory formalities with respect to the organization of the district have been complied with, and the attack is upon the face of the proceedings and on the ground mentioned above. We have therefore the single question whether or not the organization, on its face, purports to provide for the construction of disconnected projects without real unity, so that the real property in the city will be assessed in the same proportion for separate and distinct improvements.

It may be said, in the beginning, that our statutes on this subject contemplate the organization of districts to construct improvements which constitute single projects, and wholly disconnected improvements cannot be joined together in one district. This is so because special taxation for local improvements must be based upon special benefits to be derived from the construction of the improvement, and property in a given locality cannot be taxed for benefits confined to property in another locality — the benefits must result to the property to be taxed. *Swepston*v. *Avery,*118 Ark. 294. However, this court laid down the rule many years ago that “the action of a city council in including property in an improvement district is, except when attacked for fraud or demonstrable mistake, conclusive of the fact that such property is ‘adjoining the locality to be affected’ by the improvement, within the meaning of the Constitution.” *Little Rock v. Katzenstein,*52 Ark. 107. This rule necessarily implies that the determination of the city council *315as to the singleness and unity of the project, as well as the selection of the property to be benefited thereby, is conclusive, except for fraud or demonstrable mistake. The rule has been thus applied and followed in numerous later decisions of the court. *Matthews*v. *Kimball,*70 Ark. 451; *Board of Improvement*v. *Offenhauser,*84 Ark. 257; *Freese*v. *Improvement District,*126 Ark. 172; *Bennett*v. *Johnson,*130 Ark. 507; *Tarvin*v. *Road Imp, Dist. No. 1 of Perry County,*137 Ark. 354; *Van Dyke*v. *Mack,*139 Ark. 524; *Booe*v. *Sims,*139 Ark. 595; *Easley*v. *Patterson,*142 Ark. 52; *Johns*v. *Road Imp. Districts of Bradley Co.,*142 Ark. 73; *White*v. *Ark. & Mo. Highway Dist.,*147 Ark. 160; *Arkansas Foundry Co.*v. *Stanley,*150 Ark. 127. The same principle was conversely applied in the case of *Bottrell*v. *Hollipeter,*135 Ark. 315, where we held that the action of the city council in separating projects into different districts, which might in some respects appear to be single, was conclusive, in the absence of demonstrable mistake. Applying that rule to the present case, it cannot be said that the action of the city council in grouping together into a single district. the improvement of the streets designated in the organization of this district is invalid. In other words, lack of unity in the project is not so apparent as to manifest a demonstrable mistake which renders the organization of the district void.

The enlargement of the area of improved territory, which is to be accomplished by adding the improvement of the streets included in the present district, and the fact that the new improvement now contemplated will be connected together by other improved streets, presents a situation which fails to demonstrate a mistake in joining together the different parts of this improvement as a single one. The situation is one, rather, which the city council might, or might not, have treated as containing either a single or as several separate projects, according to the judgment of the members of the council, and the determination of the council should not, *316under those circumstances, be disregarded by the court as an arbitrary and demonstrable mistake.

We are not dealing- now with the question of assessment of benefits, for that must be dealt with in the manner prescribed by statute, where many considerations may be included, such as the proximity to streets to be improved, the fact that property has already been taxed to pay for improvement of intervening streets, as well as other things which affect the question of amount of benefits and uniformity of taxation.

Our conclusion therefore is that the chancery court was correct in its decree, aud the same is affirmed.
