This appeal stems from the refusal of the trial court to entertain a declaratory judgment action brought by the plaintiff. There is no dispute as to the facts. The defendant commission admitted the allegations of the complaint and the parties have stipulated to certain facts and exhibits as the only evidence in the case.
The plаintiff is a property owner and a builder of residential homes in the town of Redding where he owns an 11.6 acre parcel of land and certain other properties. In 1974, the Redding conservation commission, the town’s inland wetlands agency, adopted regulations which prohibited the installation of septic systems within fifty feet of a wetland or within *175 150 feet of а watercourse. Part of the plaintiff’s 11.6 acre parcel is designated as wetland and contains two watercourses.
In 1977, the plaintiff applied for a permit to build a residential dwelling on a portion of the 11.6 acre parcel. He was denied a building permit on the ground that the location of the proposed septic system was less than 150 feet from a watercourse and was therefore in violation of the town’s inland wetlands regulations. After the refusal, the plaintiff applied to the commission for an inland wеtlands permit, reserving by letter his right to challenge its jurisdiction over his application. When the plaintiff subsequently brought an action for mandamus the commission issued a permit for his seрtic system.
The plaintiff now seeks to construct a second dwelling on the 11.6 acre parcel. Because the second septic system will be within fifty feet of a wetland and within 150 fеet of a watercourse, the plaintiff will be unable to obtain a building permit until the commission has issued him a new inland wetlands permit. In this instance, however, the plaintiff has refused to аpply for such a permit on the ground that the commission lacks jurisdiction over the proposed septic system. Instead he has brought a declaratory judgment action сhallenging the jurisdiction of the commission and attacking the validity of certain of its regulations.
In his complaint the plaintiff alleges that he resides in Redding and intends to construct othеr dwellings in the town, that a significant portion of the town contains wetlands and watercourses, that *176 the commission’s enforcement of its regulations will affect him personally with resрect to his contracting business and with respect to other properties owned by him, and that the enforcement will also affect other persons with property similarly situаted.
The plaintiff then made the following claims: (1) activities outside of a wetland or watercourse do not require a permit from the commission and to the extent that the сommission’s regulations attempt to regulate such activities the regulations are illegal; (2) to the extent that the commission’s definition of a watercourse includes vernal or intermittent watercourses, such definition is illegal because it is attempting to regulate something which is not a body of water and thus exceeds the scope of the authority givеn by the General Statutes; (3) a septic system intended for use as part of a single family residence is a use incidental to the enjoyment of residential property and does not require a permit from the commission, even if located in a wetland, and such a septic system is not subject to the jurisdiction of the commission unless it is actually polluting a wеtland or a watercourse; and (4) exclusive jurisdiction over septic systems resides in the state health department and in the department of environmental protectiоn and the commission has no authority to regulate such systems except to the extent that such systems are located within a wetland or watercourse and constitute a “rеgulated activity” as defined by the state statute. In his prayer for relief the plaintiff sought a declaratory judgment, and an injunction restraining the commission (1) from interfering with the constructiоn of his proposed septic system and (2) from enforcing any section of its regulations which the court found to be invalid.
*177 Notice of the declaratory judgment action was givеn to all necessary and interested parties as required by the rules of practice. Practice Book, 1978, §390 (d). The trial court, however, declined to entertain the aсtion on the ground that the issues the plaintiff sought to have litigated could be more appropriately resolved by applying to the commission for an inland wetlands permit аnd, if rejected, by taking an appeal from such denial pursuant to § 22a-43 of the General Statutes. Prom that judgment the plaintiff has taken this appeal claiming that the trial court erred in refusing to entertain his action and in concluding that he should be left to seek redress by other forms of procedure.
The defendant commission, however, argues that when a party has a right of appeal from a decision of an administrative agency, he may not instead bring an independent action to test the very issue which the appeal was designed to test;

Declaratory judgment proceedings are appropriate for determining rights in connection with the regulations of an administrative agency.
Hartford Electric Light Co.
v.
Water Resources Commission,
As аlready noted, the plaintiff alleges that the commission lacks jurisdiction over septic systems, that the regulations of the commission attempting to regulate the location of such systems are invalid, and that the plaintiff does not need to apply for a wetlands permit before installing his proposed septic system. That these claims are jurisdiсtional in nature and appropriate for resolution by means of declaratory judgment is apparent. It is also apparent that these claims raise issues of statutory interpretation, which the expertise of the administrative agency would be of little value in resolving.

While exhaustion of administrative remedies is generally held to be applicable to prоceedings

involving judicial review of administrative agency action, there are certain exceptions to the rule. As already noted, one such exception is that resort to administrative agency procedures will not be required when the claims sought to be litigated are jurisdictional. See

Another exception is that exhaustion of administrative remedies will not be required when the remedies available are futile or inadequate.
Kosinski
v.
Lawlor,
In the present ease there is some question as to whether the plaintiff’s claims could properly be litigated by way of appeal because of the rule that a party who seeks some advantage under a statute or ordinance, such as a permit or a variance, is precluded from subsequently attacking the validity of the statute or ordinance.

v.
Darien,
In light of the above, this court is compelled to conclude that the trial court erred in declining to assume jurisdiction on the ground that the plaintiff should be left to seek redress by other forms of procedure.
There is error, the judgment is set aside and the case remanded for further proceedings according to law.
In this opinion the other judges concurred.
