APPEAL OF NEW HAMPSHIRE
DEPARTMENT OF ENVIRONMENTAL SERVICES
(New Hampshire Wetlands Council)

Argued: November 6, 2019
Opinion Issued: May 22, 2020

Gordon J. MacDonald, attorney general (K. Allen Brooks, senior assistant
attorney general, and Joshua C. Harrison, assistant attorney general, on the
brief, and Mr. Brooks orally), for the petitioner.

Cronin, Bisson & Zalinsky, P.C., of Manchester (John G. Cronin and
Daniel D. Muller, Jr. on the brief, and Mr. Cronin orally), for the respondents.

HANTZ MARCONI, J. The petitioner, New Hampshire Department of
Environmental Services (DES), appeals a decision of the New Hampshire
Wetlands Council remanding an administrative order issued by DES that
directed the respondents, Bryan and Linda Corr, to cease and desist
unpermitted work on their lakefront property. We affirm in part, vacate in
part, and remand.

A. Underlying Facts

The following facts were found by the Council, or are otherwise derived
from the administrative record. The Corrs own property in Moultonborough
located on the shore of Lake Winnipesaukee. When they purchased the
property, it contained a dry boathouse, positioned approximately two feet from
the shore, which was partially collapsed as a result of snow load. The
boathouse was considered a “grandfathered” or nonconforming structure for
purposes of the Shoreland Protection Act, see RSA ch. 483-B, and DES
regulations. The height of the nonconforming structure was approximately
seventeen feet.

The Corrs made plans to replace the boathouse. They hired a land use
consultant to assist them with the process, which required approvals from the
Town of Moultonborough, as well as DES. First, the Corrs filed an application
for a Wetlands Permit By Notification (PBN) with DES.1 This permit was
accepted by DES with the following project description: “Replace an existing
shoreland structure which was collapsed by snow load with a new structure in
exact location and height.”

Prior to starting construction, however, the Corrs decided to set the
boathouse back from the shoreline approximately ten feet. They sought and
were granted a building permit from the Town based on plans that included the
ten-foot added distance from the shoreline, as well as an increased height
maximum of 27 feet for the structure. The Town zoning ordinance limits the
height of structures to 32 feet.

The Corrs next sought to amend their initial PBN filed with DES. DES
did not allow the amendment, and instead required the Corrs to file a new PBN,
which they did. This Shoreland PBN2 was accepted by DES with the following
project description:

A previously existing grandfathered structure collapsed from snow
load. A previous wetlands approval was granted . . . to replace the

1Pursuant to DES rules governing wetlands, the “repair of an existing docking structure,” such as
a boathouse, see N.H. Admin. R., Env-Wt 303.04(v), qualifies for the “permit by notification
process,” N.H. Admin. R., Env-Wt 506.01(a)(5), which allows an applicant to obtain a permit for a
minimum-impact project simply by notifying DES of the proposed project. N.H. Admin. R., Env-
Wt 303.04, 506.02.

2 Pursuant to the Shoreland Protection Act and DES rules governing water quality and quantity, a
project “that impacts less than 1,500 square feet and adds no more than 900 square feet of
impervious area within a protected shoreland” qualifies for the PBN process. RSA 483-B:5-b,
I(a)(1) (2013); N.H. Admin. R., Env-Wq 1406.05.

2
 structure in kind. This application is to replace the structure
moving it back 10’ as a result of a variance granted by the
Moultonborough ZBA. The project would involve 1,480 SF of
temporary disturbance but result in no additional impervious area
because the new structure will be the exact footprint of the original
structure. The result would be a more nearly conforming
structure.

The form an applicant must fill out to submit a Shoreland PBN application
does not require the applicant to submit any information regarding the
project’s height.

After obtaining the building permit from the Town and the PBN from
DES, the Corrs commenced construction. They spent over $100,000 on the
permitted structure. When the structure was framed and nearing completion,
DES visited the site to conduct an inspection, purportedly in response to a
complaint the department had received. Subsequently, DES issued a Letter of
Deficiency to the Corrs informing them that the structure was 27 feet tall, and
therefore not compliant with DES regulations.

After a series of communications between the Corrs and DES, the
department issued an administrative order declaring that the Corrs’ structure
was not compliant with Env-Wq 1405.03(b)(1) because it was taller than 12 feet
in height. See N.H. Admin. R., Env-Wq 1405.03(b)(1) (restricting the maximum
height to 12 feet for accessory structures located within the shoreline and the
primary building line). DES instructed the Corrs that, to be compliant with
DES regulations, the building needed to be no greater than 17 feet, the height
of the original boathouse. In addition, the order directed the Corrs to cease
and desist construction on their property. In compliance with the order, the
Corrs have not undertaken further work on the building and the structure
remains unusable.

B. Proceedings Before the Wetlands Council

The Corrs notified DES that they planned to challenge the department’s
authority to restrict the height of the structure, and subsequently appealed
DES’ administrative order to the Council. In their appeal, the Corrs raised four
alternative arguments as to how DES had acted unlawfully and unreasonably
in issuing its order: (1) DES lacks statutory authority to restrict the height of
buildings within the protected shoreland; should such authority exist, the lack
of a standard for determining the height of a building renders that authority
unenforceable; (2) DES’ authority to restrict height is limited to “small”
accessory structures, and the Corrs’ structure is not “small”; (3) DES erred in
applying its height restriction for small accessory structures to the Corrs’
structure, which should have been evaluated by DES as a nonconforming

3
structure under RSA 483-B:11, I (2013);3 and (4) DES’ order should have
applied a vested rights exemption or granted the Corrs a waiver of the rules.

After receiving notice of the appeal, the Council requested and received
the assignment of a hearing officer from the New Hampshire Attorney General.
Prior to a hearing before the Council, DES filed a motion to dismiss, in which it
argued that the Corrs had failed to demonstrate that the department had acted
unlawfully and unreasonably in restricting the height of the structure, and in
failing to apply a vested rights exemption or grant a waiver. DES requested
that the motion “be ruled on by the Hearing Officer pursuant to RSA 21-M:3,
IX(e).”4 The Corrs filed an objection to DES’ motion to dismiss, expanding upon
the arguments raised in their initial petition.

The hearing officer issued an order (dismissal order) granting in part and
denying in part DES’ motion to dismiss. Assuming the facts alleged by the
Corrs to be true, see Hobin v. Caldwell Banker Residential Affiliates, 144 N.H.
626, 627 (2000), and ruling on issues of law, see RSA 21-M:3, IX(d) (2012)
(stating that the hearing officer is to “[d]ecide all questions of law presented
during the pendency of the appeal”), the hearing officer determined that: (1) the
Corrs’ structure is an “accessory structure” as defined by RSA 483-B:4, II
(2013); (2) DES has the authority to restrict the height of accessory structures
pursuant to RSA 483-B:17, IV (2013); and (3) the Corrs’ structure was not
made “more nearly conforming” than the original nonconforming structure, see
RSA 483-B:11, I; N.H. Admin. R., Env-Wq 1408.05, because the height of the
structure was increased by ten feet. The hearing officer left the following
factual determinations for the Council: (1) whether DES’ methodology for
measuring height in this case is arbitrary and subject to unfettered discretion;
and (2) whether the Corrs were entitled to a vested rights determination or (3)
whether the Coors were entitled to a waiver of regulations.

3 RSA 483-B:11, I, states, in relevant part:

Except as otherwise prohibited by law or applicable municipal ordinance,
nonconforming structures located within the protected shoreland may be
repaired, replaced in kind, reconstructed in place, altered, or expanded. Repair,
replacement-in kind, or reconstruction in place may alter or remodel the interior
design or existing foundation of the nonconforming structure, but shall result in
no expansion or relocation of the existing footprint within the waterfront buffer.
However, alteration or expansion of a nonconforming structure may expand the
existing footprint within the waterfront buffer, provided the structure is not
extended closer to the reference line and the proposal or property is made more
nearly conforming than the existing structure or the existing conditions of the
property.

4 RSA 21-M:3, IX(e) provides that a hearing officer, when designated for a particular appeal, shall
“[p]repare and issue written decisions on all motions . . . .” RSA 21-M:3, IX(e) (2012).

4
 Following a hearing,5 the Council issued an order (initial order), signed
by the hearing officer, concluding that, once the Corrs’ structure was set back
from the shoreline, DES acted unlawfully in regulating it as a newly
constructed “accessory structure,” to which its 12-foot height restriction
applied, see RSA 483-B:17, IV; N.H. Admin. R., Env-Wq 1405.03, rather than
as a nonconforming structure replaced by a “more nearly conforming”
structure, to which its height restriction did not apply, see RSA 483-B:11
(2013). The Council stated that, given the new placement of the structure 10
feet back from the shoreline, as well as the storm water management features
detailed in the structure’s design plans, it was possible that the structure had
become “more nearly conforming than the existing structure” in compliance
with RSA 483-B:11. The Council remanded DES’ order to the department for
consideration of the structure’s compliance with RSA 483-B:11.

DES filed a motion to reconsider, contending that, in its initial order, the
Council had improperly overruled a legal determination made by the hearing
officer. DES argued that, by ruling that the Corrs’ structure should be
regulated by the department as a “nonconforming structure” rather than an
“accessory structure,” the Council had ignored the hearing officer’s legal
determination that DES has the authority to restrict the height of the Corrs’
structure as an “accessory structure.” DES also contended that the Council
had failed to decide the discrete factual issues reserved for it by the hearing
officer in his order on the department’s motion to dismiss. The Corrs filed an
objection to DES’ motion to reconsider, requesting that the Council deny the
motion, or, in the alternative, supplement the order with a finding that DES’
enforcement of a height limitation in this case is arbitrary, capricious, and
unenforceable.

In an order on DES’ motion to reconsider (reconsideration order), signed
by both the hearing officer and the Council chairman, the Council adopted
statements made by the hearing officer during the Council’s deliberations on
the motion to reconsider, specifically that “the Council’s consideration . . . of
the applicability of RSA 483-B:11 was tied to the question of height raised by
the appellants,” was not estopped by the hearing officer’s ruling on the motion
to dismiss, and, “being a question of applying fact to relevant law,” was “within
Council authority.” See RSA 21-M:3, IX(c) (2012) (stating that the hearing
officer shall “[d]eliberate with the council before reaching conclusions on mixed
questions of law and fact”). The Council also explained that its wording had
been “inexact” when it stated in its initial order that the Corrs’ structure was a
nonconforming structure “rather than an accessory structure.” The Council
clarified that “[t]he structure under consideration . . . is a nonconforming
accessory structure.” Maintaining that a “salient point” of its initial order was
that “[t]he structure is a nonconforming structure,” the Council reiterated that

5 At the hearing, the Council heard testimony from respondent Bryan Corr, a Town building code
official, a private storm water management consultant, and three employees from DES.

5
the department had “failed to consider that by moving the building back from
shore 10 feet, the building is more nearly conforming to RSA [chapter] 483-B.”

Turning next to DES’ argument that the Council had neglected to decide
the factual issues posed to it by the hearing officer, the Council concluded that
DES’ “height measurement method was unreasonable.” It also concluded that,
by accepting DES’ allegations of fact in its initial order that the Corrs had never
submitted documentation claiming a vested rights exemption or requested a
waiver, it had denied the Corrs’ arguments that they were entitled to the vested
rights exemption or a waiver of the rules. Nevertheless, the order stated that
“[t]he Hearing Officer noted, and the Council agreed, that in a situation like
this, DES is required to make a reasonable effort to consider all statutory
avenues and possible waivers to resolve the dispute.” This appeal followed.

II

We begin by addressing DES’ contention that the final order of the
Council is unlawful because it overrules a decision of the hearing officer on
matters of law. Our standard of review of the Council’s decision is set forth in
RSA 541:13 (2007). Appeal of Lake Sunapee Protective Ass’n, 165 N.H. 119,
124 (2013); RSA 21-O:14, III (Supp. 2019). Under this statute, the Council’s
findings of fact “shall be deemed to be prima facie lawful and reasonable.” RSA
541:13. DES, as the petitioner, has the burden of demonstrating that the
Council’s decision was “clearly unreasonable or unlawful.” Id. We must
uphold the Council’s decision except for errors of law, unless we are satisfied,
by a clear preponderance of the evidence before us, “that such order is unjust
or unreasonable.” Id.

The Council’s review of DES decisions is governed by RSA 21-O:14
(Supp. 2019). See RSA 21-O:5-a, V (2012). It is the Council’s role to
“determine whether the department decision was unlawful or unreasonable by
reviewing the administrative record together with any evidence and testimony
the parties to the appeal may present.” RSA 21-O:14, I-a. Hearings before the
Council “shall be conducted in accordance with the provisions of RSA 541-A
governing adjudicative proceedings by an administrative hearing officer
assigned by the department of justice,” and “[a]ll issues shall be determined as
specified in RSA 21-M:3, IX.” RSA 21-O:14, II.

Pursuant to the version of RSA 21-M:3, IX in effect at the time the Corrs’
appeal was before the Council, a designated hearing officer shall:

(a) Regulate all procedural aspects of a proceeding, including
presiding over the hearing and any prehearing conferences;

(b) Adopt all findings of fact made by the council except to the
extent any such finding is without evidentiary support in the

6
 record;

(c) Deliberate with the council before reaching conclusions on
mixed questions of law and fact;

(d) Decide all questions of law presented during the pendency of
the appeal; and

(e) Prepare and issue written decisions on all motions and on the
merits of the appeal within 90 days of the conclusion of the
hearing on the merits. The hearing officer shall provide the council
with a proposed written decision on the merits within 45 days of
the conclusion of the hearing on the merits. If requested to do so
by the members of the council participating in the discussion, the
hearing officer shall meet with those members within the 90 day
period to discuss the decision.

RSA 21-M:3, IX (2012).6

DES argues that the Council’s final order is unlawful because it
overrules the decision of the hearing officer on questions of law, determinations
of which are to be decided solely by the hearing officer. See RSA 21-M:3, IX(d).
DES contends that, in determining that the Corrs’ structure should be
regulated by DES as a “nonconforming structure,” see RSA 483-B:11, the
Council’s initial order contravened the hearing officer’s conclusion that,
because the building was an “accessory structure,” see RSA 483-B:17, IV, DES’
restriction of its height was proper. DES further contends that the Council’s
reconsideration order was similarly unlawful because it departed from the
hearing officer’s dismissal order, as well as the Council’s own initial order, by
(1) characterizing the issue presented by DES’ motion as a “mixed question of
law and fact,” and (2) applying applicable law to the facts presented, both in
violation of RSA 21-M:3, IX. In response, the Corrs assert, among other things,
that, to the extent the hearing officer and the Council were not compliant with
RSA 21-M:3, IX, DES’ procedural claim fails, as DES has not succeeded in
demonstrating material prejudice.

We will not set aside an agency’s decision for a procedural irregularity
unless the complaining party shows material prejudice. Ruel v. N.H. Real
Estate Appraiser Bd., 163 N.H. 34, 44 (2011). DES bears the burden of

6 The current version of RSA 21-M:3, IX, which went into effect on July 1, 2019, is substantially
similar but includes an additional requirement that the hearing officer, at the first prehearing
conference, “order the parties . . . to participate in mediation if the hearing officer concludes that it
is reasonably possible that mediation will result in the resolution of the issues in dispute in the
proceeding,” RSA 21-M:3, IX(b) (Supp. 2019), and substitutes “100” for “90” in the first and third
sentences of IX(e), see RSA 21-M:3, IX(f) (Supp. 2019).

7
showing that any such irregularities materially prejudiced it. Id. In making
such a showing, conclusory assertions of prejudice are insufficient. Id.

DES’ sole contention of prejudice is that, following the Council’s
reconsideration order, it was “left . . . in the impossible position of trying to
comply with two conflicting final orders.” We disagree with this
characterization. The transcript of the initial hearing deliberations evidences
the Council’s recognition and consideration of the hearing officer’s prior ruling.
Statements by council members made during those deliberations exhibit their
acknowledgment that the hearing officer had already determined that height
may be restricted by DES under RSA 483-B:17, IV, and that he had reserved
“three issues” for the Council’s consideration. The record also indicates that
the Council believed that, if it made an affirmative determination on the first
issue before it, i.e., that DES’ method for determining height in this case is
arbitrary and capricious, it would be unnecessary to address the two remaining
issues: whether the Corrs were entitled to (1) a vested rights determination or
(2) a waiver of regulations.

More importantly, the record supports the hearing officer’s acceptance of
the Council’s determinations in its initial order. Prior to issuance of the order,
the hearing officer e-mailed the Council appeals clerk with his corrections to
the order, evincing his approval of the order conditioned on his edits. In
addition, the Council’s initial order includes the signatory line, “By Order of the
hearing officer,” followed by the hearing officer’s signature. Thus, to the extent
the Council’s initial order conflicted with the hearing officer’s dismissal order,
the record indicates that the hearing officer expressly adopted those
inconsistencies.

The same is true with regard to the Council’s reconsideration order. In
its motion to reconsider, DES argued that the Council had failed to address, in
its initial order, the three issues reserved for it by the hearing officer. In the
Council’s reconsideration order, it explained that, based on comments made by
the hearing officer during deliberations on the motion to reconsider, the
Council understood that the applicability of the statute governing
nonconforming structures was “tied to the question of height raised by the
appellants,” was not estopped by the dismissal order, and, “being a question of
applying fact to relevant law,” was “within Council authority.” Although the
Council’s reconsideration order was signed by the Council chairman, like the
initial order, it included the signature of the hearing officer, indicating intent
on the part of the hearing officer to join in the reasoning of the Council’s order.
The record demonstrates a clear intent on the part of the hearing officer to join
in the Council’s subsequent orders to the extent they contradicted his earlier
rulings. Therefore, DES has failed to demonstrate material prejudice, and we
will not set aside the agency’s decision on procedural grounds. See Ruel, 163
N.H. at 44.

 III

We next consider DES’ argument that the Council’s decision was
unlawful and unreasonable because it ignored DES’ 12-foot height restriction,
see N.H. Admin. R., Env-Wq 1405.03(b)(1), and interpreted and applied RSA
483-B:117 in a manner that grants “seemingly unlimited expansion rights” to
the Corrs. In response, the Corrs contend, among other things, that the
Shoreland Protection Act, specifically RSA 483-B:17, IV, does not afford DES
the authority to restrict their structure’s height.8 They argue that, rather than
granting authority to DES to restrict the height of accessory structures
generally, RSA 483-B:17, IV confers on DES the limited authority to restrict the
height of “small accessory structures such as storage sheds and gazebos.” RSA
483-B:17, IV (emphasis added). The Corrs assert that, because their structure
is not a “small accessory structure,” DES does not have authority to restrict its
height pursuant to Env-Wq 1405.03(b)(1).

This issue requires us to interpret both state statutes and administrative
rules, and we use the same principles of construction when interpreting both.
Petition of Parker, 158 N.H. 499, 502 (2009). We ascribe the plain and
ordinary meanings to words used, looking at the rule or statutory scheme as a
whole, and not piecemeal. Id. Although we accord deference to an agency’s
interpretation of its own regulations, that deference is not total. Id. We still
must examine the agency’s interpretation to determine if it is consistent with
the language of the regulation and with the purpose which the regulation is
intended to serve. Id. Our review of the agency’s interpretation of state law
and administrative rules is an issue of law, which we review de novo. See
Appeal of Morton, 158 N.H. 76, 78 (2008); RSA 541:13.

The Shoreland Protection Act, RSA chapter 483-B, establishes
“standards for the subdivision, use, and development of the shorelands of the
state’s public waters” to “promote public health, safety, and the general
welfare.” RSA 483-B:2 (2013). The Act states that “[t]he shorelands of the
state are among its most valuable and fragile natural resources and their
protection is essential to maintain the integrity of public waters.” RSA 483-
B:1, I (2013). It also provides that “[t]he state has an interest in protecting [its

7 Because we conclude that DES did not have the authority to restrict the height of the Corrs’
structure under RSA 483-B:17, IV, we need not determine whether it was proper for the Council
to apply RSA 483-B:11 in considering the lawfulness of DES’ administrative order.
8
We note that this argument was presented by the Corrs in the form of a cross-appeal. DES filed
a motion to dismiss the Corrs’ cross-appeal, contending that it was barred due to the Corrs’
failure to file a motion to reconsider with the Council. The Corrs objected, and, prior to oral
argument, we denied DES’ motion to dismiss without prejudice to raising the argument in an
answering brief. We treat the Corrs’ argument not as a cross-appeal, but rather as a response to
DES’ argument that the Council erred in interpreting and applying RSA 483-B:11. Thus, DES’
motion to dismiss is moot.

public] waters and has the jurisdiction to control the use of the public waters
and the adjacent shoreland for the greatest public benefit.” RSA 483-B:1, II
(2013).

RSA 483-B:17, IV, a provision of the Act, authorizes the commissioner of
DES to adopt rules relative to “[p]rocedures and criteria for the size and
placement of small accessory structures such as storage sheds and gazebos,
which are consistent with the intent of [the Act], between the reference line9
and the primary building line.” RSA 483-B:17, IV. Under the authority
granted to it by RSA 483-B:17, IV, DES promulgated administrative rule Env-
Wq 1405.03, Limitations on Accessory Structures within the Waterfront Buffer,
which, according to DES, applies “to accessory structures located between the
reference line and the primary building line,” and includes a requirement that
accessory structures “[n]ot exceed 12 feet in height.” N.H. Admin. R., Env-Wq
1405.03(a), (b)(1).

“An administrative agency must comply with the governing statute, in
both spirit and letter.” Appeal of Rainville, 143 N.H. 624, 627 (1999) (quotation
omitted). “Even a long-standing administrative interpretation of a statute is
irrelevant if that interpretation clearly conflicts with express statutory
language.” Id. (quotation omitted). Agency regulations that contradict the
terms of a governing statute exceed the agency’s authority. Appeal of Gallant,
125 N.H. 832, 834 (1984).

DES would have us interpret RSA 483-B:17, IV to authorize the
department to restrict the height of all accessory structures between the
reference line and the primary building line. However, that interpretation
would ignore the plain language of the statute. See Appeal of Astro
Spectacular, 138 N.H. 298, 300 (1994) (stating that, when interpreting a
statute, the court “can neither ignore the plain language of the legislation nor
add words which the lawmakers did not see fit to include” (quotation omitted)).
In RSA 483-B:17, IV, the adjective “small” modifies the phrase “accessory
structure,” and thereby limits the scope of the provision. Reid v. N.H. Attorney
Gen., 169 N.H. 509, 522 (2016) (explaining that the adjectives in a statute
modify the words that follow them, and “thereby circumscrib[e] the provision’s
scope”). We decline to adopt DES’ interpretation, as it would render the word
“small” meaningless. See Marceau v. Concord Heritage Life Ins. Co., 149 N.H.
216, 219 (2003) (declining to interpret a statute in a manner that would render
a phrase within the statute “virtually meaningless”).

DES’ interpretation would also require us to overlook 483-B:4, II, which
defines “accessory structure” as “a structure . . . on the same lot and

9The “reference line” for lakes is “the surface elevation as listed in the Consolidated List of Water
Bodies subject to the shoreland water quality protection act as maintained by [DES].” RSA 483-
B:4, XVII(a) (2013).

10
customarily incidental and subordinate to the primary structure”; “or a use,
including but not limited to paths, driveways, patios, any other improved
surface, pump houses, gazebos, woodsheds, garages, or other outbuildings.”
RSA 483-B:4, II. See Petition of Parker, 158 N.H. at 502 (stating that we look
at the statutory scheme as a whole, and not piecemeal). In considering the
statutory scheme as a whole, the definition of accessory structure in RSA 483-
B:4, II is quite broad compared to the language used in RSA 483-B:17, IV.
DES’ authority to impose size10 restrictions under RSA 483-B:17, IV is limited
to “small accessory structures such as storage sheds and gazebos,” rather than
accessory structures generally, as DES contends. Furthermore, accepting
DES’ interpretation would also be at odds with the absence in the Act of height
limitations on primary structures.

Finally, we examine an agency’s interpretation of its own regulation to
determine if it is consistent with the purpose which the regulation is intended
to serve. Petition of Parker, 158 N.H. at 502. DES has failed to demonstrate,
particularly in the circumstances of this case, how height has any relation to
the protection of the public waters and the adjacent shoreland. See RSA 483-
B:1, II, :17, IV (limiting DES’ authority to adopt rules relative to the size of
small accessory structures to those that “are consistent with the intent” of the
Act). Indeed, the Council found that “[t]he height of the [Corrs’] structure has
no negative impact on water quality or wetlands,” and DES has not alleged any
violation of department rules other than the height requirement of Env-Wq
1405.03(b)(1). See RSA 483-B:5-b, I(a) (2013) (stating that projects qualify for
PBNs when they “have no impact on water quality” and “follow department
rules”).

We agree with the Corrs that DES did not have the authority to limit the
height of their structure. The plain language of RSA 483-B:17, IV does not
grant DES the authority to restrict the height of all accessory structures, only
those that are “small.” RSA 483-B:17, IV. The Council found that “[t]he
structure in dispute is not a small accessory structure such as a gazebo or a
shed,” and this finding is “deemed to be prima facie lawful and reasonable.”
RSA 541:13. Given our determination that DES is without such authority, it
necessarily follows that the height requirement set forth in Env-Wq
1405.03(b)(1) does not apply to the structure.

Contrary to DES’ assertion, this determination does not mean that
structures such as the Corrs’ are entirely outside the bounds of state regulation.
Accessory structures that are not considered small must still meet the provisions
of the Act that govern structures located within the protected shoreland. In

10Given our previous determination that “size” means “physical magnitude, extent, or bulk: the
actual, characteristic, normal, or relative proportion of a thing,” Cosseboom v. Town of Epsom,
146 N.H. 311, 315 (2001) (citing Webster’s Third New International Dictionary 2131 (unabridged
ed. 1961)), we interpret the plain meaning of “size” to encompass “height.”

addition, a structure’s height is subject to municipal zoning restrictions. The
Corrs were aware of these restrictions, which is why they hired a land use
consultant to assist them with the permitting process. They received approval
from the Town for their redevelopment plan, and stayed within the height
requirements prescribed by the Town: constructing a 27-foot building in
compliance with the Town’s 32-foot height restriction. Because we conclude that
DES did not have the authority to restrict the height of the Corrs’ structure
under RSA 483-B:17, IV, we need not determine whether it was proper for the
Council to apply RSA 483-B:11 in considering the lawfulness of DES’
administrative order.

In light of our determination that the Corrs’ structure is not governed by
Env-Wq 1405.03(b)(1), we affirm the Council’s decision to the extent that it
concluded that the rule’s 12-foot height restriction does not apply to the Corrs’
structure. However, we vacate all other aspects of the Council’s decision. We
remand the matter to the Council with instructions to grant the Corrs’ appeal
and to vacate DES’ administrative order, which relied solely on the alleged
height violation. In light of the result reached, we need not address any
additional arguments raised by the parties. See State v. Sargent, 144 N.H.
103, 106 (1999) (concluding that result obviated need to address remaining
arguments).

Affirmed in part; vacated in part;
and remanded.

HICKS, BASSETT, and DONOVAN, JJ., concurred.
