This packet is for the Centreville Planning Commission meeting on November 20, 2024 at 7:00 p.m. and includes the agenda items: approval of prior meeting minutes, citizen comments, and a scheduled appearance on a Final Site Plan for a proposed mixed-use development by Hillside Liquors, LLC on the lands of Corsica Creek Commons, LLC at 425 S. Commerce Street presented by Brandon A. Davis of DMS & Associates. The submitted final site plan converts a previously reviewed preliminary set into a construction-ready set, with architectural and site details: a two-level building (Level 1 liquor store ~6,048 SF; Level 2 apartments ~6,048 SF; stairs add 308 SF per level; a 735 SF roof deck; total building area 13,755 SF), parking at the side and rear with one-way counterclockwise circulation designed to accommodate semi-trailer deliveries, sidewalks along the parking area, and a 735 SF roof deck for residents. The compliance checklist and drawings describe prominent covered storefront entries with canopies, a blank brick-faced north wall to enclose a walk-in cooler with belt coursing and decorative recesses, proposed buffer plantings and a 6-foot privacy fence along the north property line, building materials (brick veneer, aluminum siding panels, aluminum storefront, clad wood windows, galvanized railings, aluminum fascia and louvers, internally lit box signs), and a note that a stair tower may exceed the 35-foot height limit by up to 25% (to 43'-9"). The packet also lists agenda zoning discussion of draft Traditional Neighborhood Development / Complete Neighborhood PUD language, a letter from Centreville Town Council about Development Design Standards, and the approved building permit list issued October 2024.

Introduction: The site is located at 425 S. Commerce Street, Centreville, Maryland 21617 (the “Property”), across Mill Stream from the existing Hillside Liquor store. The Property is designated as Tax Map 44B, Parcel 1085. Hillside Liquors and Deli, LLC (“Applicant”), proposes to construct a new commercial retail building with a liquor store on the first floor and apartments on the second floor (the “Project”). The Project will have associated parking, pedestrian connectivity, landscaping, utility connections, and stormwater management, all of which are compliance with State and local design requirements and codes as proposed by the Applicant. The Property is currently vacant and is zoned C-2 and within the Intensely Developed Area of the Chesapeake Bay Critical Area. The Property is designated as a Buffer Modified Area and is located within the FEMA floodplain zone, AE designation, and floodway. The Property was formerly improved with a large industrial building that was demolished pursuant to an agreement with the Town of Centreville. The preexisting building and agreement with the Town makes the site eligible for redevelopment. Site Plan Criteria: The criteria for approval of a site plan are set forth in § 170-47 of the Code of the Town of Centreville. A site plan must also satisfy the Development Design Standards which are incorporated into the Code at § 170 as Attachment 6; because the proposed development is for retail and commercial apartments, the commercial design standards at Chapter 4 are applicable to the Project. Each of the criteria are addressed as follows, noting as appropriate where variances or exemptions to the criteria or standards are sought from the Commission. CODE OF THE TOWN OF CENTREVILLE, § 170-47C (Site Plans) 1. An area or vicinity map at a scale of not smaller than one inch equals 2,000 feet and showing such information as the names and numbers of adjoining roads, streams, bodies of water, railroads, subdivisions, election districts, or other landmarks sufficient to clearly identify the property. Please see Site Plan at Exhibit 1, which has a vicinity map on the cover sheet. 2. A boundary survey plat of the entire site at a scale not smaller than one inch equals 100 feet unless otherwise specified by the Planning and Zoning Commission showing the following:…[a-f.] Please see Site Plan and Existing Conditions, Pre-Existing Conditions and Demolition Plan, Exhibit 1, which comply with these requirements. The site plan and design are based on field survey data provided by Fink, Whitten & Associates. 1 3. A detailed drawing showing: …[a-r.] Please see Site Plan at Exhibit 1, which complies with this requirement. We will continue to develop the site plan based on agency comments and the progression to the final site plan approval and permit phases. 4. Computations of: …[a-k.] Please see Site Plan at Exhibit 1. The current proposal provides thirty-three (33) parking spaces. Pursuant to the Code, the two-bedroom apartments on the second floor of the building require 2.25 parking spaces each. There are six apartments, requiring a total of 13.5 spaces. The first floor has 6,356 square feet, for which, pursuant to the general category in the Code, must provide one space for each 250 square feet, or 25.4 spaces. Together, the entire building requires 38.9 – 39 rounded up – parking spaces. A reduction or variation from this requirement is sought from the Planning Commission pursuant to § 170- 32B of the Code. The parking required by the Code is more than what is needed for the building’s proposed and intended uses, which imposes unnecessary costs and dedicates space to parking “that could more desirably be used for valuable development or environmentally useful open space.” To support this request for a parking reduction, the Applicant represents that is has substantial experience with the proposed liquor- store use within the Town and elsewhere. This experience informs that 25 or 26 spaces for the proposed use at one parking space for 250 square feet – which includes the 308 feet of the store’s stairwell and 1,344 square feet of storage area that are not accessible by patrons – is excessive, creating underutilized parking areas and unnecessary impervious surfaces within the critical area. It is not realistic and an overestimation to assume that 25 to 26 patrons will be in the store at one time. The 308 feet of the stairwell does not create a parking demand and should not be accounted for in the calculation. The storage area of the store is for loading and delivery, and as such it is reasonable to apply the parking requirement for storage areas that is used by Queen Anne’s County and other jurisdictions — one space per 6000 square feet. Applying that to the 1,344 square feet of storage results in a parking requirement of only 0.2 spaces for the storage portion. Applying the 250-square-foot standard to the remaining 4,704 square feet of retail area produces a requirement of 18.8 parking spaces. That is a total of 19 parking spaces for the first floor that, when added to the 13.5 spaces required by the second-floor apartments, produces a total requirement for the building of 33 parking spaces, in accordance with the current site plan and design. This is a much more reasonable number that the Applicant believes will still provide a parking overage than what will be utilized. 5. Commercial or industrial uses must include:…[a-f.] The proposed commercial uses of the property are retail and commercial apartments. Light poles are proposed across from the driveway at the southwest corner, on an island in the rear, and against the far end of the parking strip to the south of the building. Building-mounted lighting is also proposed to light the drive on the north side of the building, the sidewalk on the southside, and under all the canopies. The light layout and fixture selection are designed to not exceed minimums established by the IESNA Recommended Practices and Design Guidelines Latest Edition and as necessary for safety. The fixtures proposed are dark-sky compliant. Lighting design has been updated and a lighting plan prepared by Torchio Architects has been submitted with this narrative (Sheet 6 of 6). 6. In addition to the information above, site plans shall be accompanied by the following: …[a-g.] Please see the Site Plan at Exhibit 1, the Stormwater Management Report attached to this narrative as Exhibit 2, and the Schematic Design, dated October 29, 2024 (the “Schematic Design”) attached to this narrative as Exhibit 3. All requirements cited above are met by the project and building design. The project team will continue to work with applicable State and Town agencies and approving authorities through 2 building permitting, stormwater design, floodplain approvals, and other permitting requirements following final site plan approval. CODE OF THE TOWN OF CENTREVILLE, § 170, ATT. 6, § 4A (Parking) 1. Commercial parking lots shall be located behind buildings. Commercial parking lots shall only be allowed to remain in front of or beside buildings as permitted by the Planning Commission. Permission from the Planning Commission is sought for placement of parking both in the rear and on the side of the Building. The need for parking on the side of the Building is a result of the irregular, elongated shape of the property; desire to retain wooded areas in the rear and maximize the distance between the building and Mill Stream; need for adequate access by emergency vehicles; and the minimization of additional unnecessary impervious surfaces in the critical area. The proposed site layout utilizes the existing site entrance as was established by the State Highway Administration when the Route 213 bridge was replaced and the taking of the associated right-of-way occurred. Parking lots shall provide a minimum 10 foot wide planting area between the parking lot and street right-of-way to include: A year-round sight barrier, Evergreen shrubs, Evergreen ground cover, Shrub material maintained at maximum height of 3 feet for visibility and maintain year- round color and interest. Landscaping of the open areas on the property will provide for the required sight barrier and evergreen and shrub cover and material. See Site Plan, Landscaping Plan, at Exhibit 1. Two trees and three shrubs in a 25-foot landscape buffer, in combination with eleven (11) parking lot screening shrubs and landscaping canopy trees, will be visible, provide a sight barrier of the parking lot, and contribute to the year-round landscaping appearance. 2. Drive-thru windows shall not be located between the building and major roadways unless permitted by the Planning Commission. Drive through areas shall be separated from parking areas and provide safe access to building entrances as approved by the Planning Commission. There are no proposed drive-through windows or areas. 3. Parking lots shall provide clear, logical, and well defined vehicular circulation within and through the lot. The vehicular circulation is arranged in a one-way, counterclockwise direction around the building that will be apparent and understandable to residents, visitors, and other motorists with the placement of traffic-flow arrows and other pavement markings throughout, as well as a one-way directional sign placed on a monumental entrance with an area of depressed curb. Planting islands and curbing shall be used to clearly define and separate travel lanes and parking areas. A triangular entrance and exit curb with signage will separate incoming and outgoing traffic. Curbs are placed at the southern and rear corners of the building to delineate parking areas apart from the travel lanes. An island is also placed in the rear of the building to set off four spots from the travel lane. Pull in or back out parking spaces are prohibited on primary vehicular travel lanes within parking lots with fifty (50) or more spaces. 3 The proposed parking lots do not have 50 or more spaces. Parking spaces are prohibited in the vicinity of the driveway entrance and/or exit. The driveway entrances and exits have no parking spaces attached or in the vicinity. Cross access easements shall be provided between commercial parcels to allow for interconnection of parking areas. There are no adjacent commercial parcels or related parking areas. Provisions shall be made to connect to future development and planned or existing adjacent parking lots by dedication of easements for future connections. There are no plans for future development or adjacent parking lots. Accommodation for loading and unloading shall be designed to provide adequate space for efficient maneuvering into and out of loading position at properly constructed docks located either within a building or in the yard on the same lot. The parking and circulation are designed to accommodate both cars, semi-trailer delivery trucks that will service the liquor store, and emergency vehicles. Trucks will park in a travel aisle in the rear that may be bypassed on the outer loop so as not to interfere with car traffic. The pavement in that delivery aisle can be striped to designate a loading zone. In response to the Planning Commission’s comments at preliminary site plan review, a “LOADING AREA” has been identified immediately adjacent to the dumpster enclosure. The loading area as proposed in 10’ by 55’ and exceeds the requirements of the subdivision regulations, which do not apply to this project but have been addressed by reference. Applicant’s design team revisited the turning radiuses coming from Commerce Street and widened the entrance and exit lanes by approximately three feet (3’) at turning areas and the drive aisles around the site have been widened from twelve feet (12’) to fourteen feet (14’). The proposed building has been shifted to the east 5’ to allow additional maneuvering space for large vehicles. 4. The number of trees required in the internal planting areas in parking lots shall be dependent on the location of the parking lot in relation to the building and public right-of-way: Where the parking lot is located between the building and the right-of-way, one tree for every five spaces shall be provided (1:5). Where the parking lot is located to the side of the building and partially abuts the right-of- way, one tree for every seven spaces shall be provided (1:7). Where the parking lot is located behind the building and is not visible from the public right- of-way, one tree for every ten spaces shall be provided (1:10). Internal Planting areas shall break up long rows of parking, and to aid and facilitate vehicular circulation through the parking lot. The Planning Commission may allow extensively landscaped storm water facilities to be counted toward the required landscaping. The parking areas are not between the building and a public right-of-way, nor abut a right-of-way. There are ten (10) parking spaces in the rear of the building, for which one tree must be provided and 23 spaces to the side of the building, for which 3.3 trees must be provided. The rate is one (1) tree per seven (7) spaces. A total of five (5) trees and 38 shrubs are provided in the parking areas to address this requirement. Landscaped areas and parking separation will further reduce the visible impact of the parking areas. 5. Parking lots that abut the public right-of-way shall be screened with one or a combination of the following treatments: 4 Low walls made of masonry, or other similar permanently affixed materials, and not exceeding a maximum height of 3 feet. Raised planter walls planted with a minimum 80% evergreen shrubs not to exceed a total height of 3 feet, including planter wall and landscape planting. Landscape plantings consisting of trees of which at least 80% are deciduous. Shrubs and groundcover materials of which at least 80% are evergreen. Walls, fencing, and architectural details shall compliment the materials used in adjacent architectural styles. Walls and raised planters shall not exceed a maximum height of 3 feet, unless a screen treatment is provided that does not create a safety hazard. Where walls are provided, landscape planting areas shall be a minimum width of 5 feet and shall be located adjacent to the public right-of-way. Fencing around parking lots shall be in conformance with the existing Town Code. All plant material used for parking lot screening shall be managed and/or selected to provide clear views between 3 and 8 feet above the ground surface, for surveillance purposes. The parking areas are not adjacent to a public right-of-way. Chain link fencing, with or without coating, shall not be used on any street frontage, adjacent to a public sidewalk or adjacent to a residential designation. Chain-link fencing is not proposed for any street frontage or area adjacent to a public sidewalk or residential designation. Board-on-board fencing is proposed to be placed between the adjacent lot that has a residential designation. 6. For parking lots that contain greater than 50 parking spaces, pedestrian connections shall be clearly defined in a combination of 2 or more of the following ways: a. Special paving, such as colored concrete, pavers, etc. in an asphalt area. b. A continuous landscape area minimum 3 feet wide on at least one side of the walkway (where walkways abut a public right-of-way and/or driving aisles, the landscape area shall be provided between the walkway and the public right-of-way or driving aisle). c. Surfacing materials must be safe and conducive for navigation by strollers, wheel chairs, walkers and carts. The parking lots do not contain greater than 50 parking spaces. ADA complaint connections shall be provided from ADA parking stalls to the main pedestrian walking routes and building entrances. Parking space striping, an ADA compliant curb, a detectable warning surface, an ADA compliant concrete sidewalk at the front, south, and east of the building, and ADA accessible ramps at the ADA parking stalls and in the rear of the building shall create access to walking routes and building entrances. Each of the two ADA compliant parking spots will be designated with ADA compliant accessible parking signate. See Site Plan, Site and Stormwater Management Profiles, at Exhibit 1. Pedestrian walkways within parking areas shall be a minimum of 5 foot width of clear, unobstructed passage. There are no pedestrian walkways within the parking areas. 5 Pedestrian walkways shall provide a distinct linkage between a main entrance to the building and a concentration of vehicle parking spaces in order to encourage its use by pedestrians. There is a sidewalk the entire length of the parking area that provides direct access to the entrance to the building. When buildings are not located directly adjacent to the sidewalk, pedestrian walkways shall connect the public sidewalk in the right-of-way to the main building entrance in a clear and direct manner, regardless of the number of parking spaces. A pedestrian walkway across the driveway entrance is five feet (5’) in width and allows for clear, direct, unobstructed passage from the public sidewalk in the right-of-way to the main building entrance. Where transit stops or pedestrian drop off sites occur in the public right-of-way (if applicable), pedestrian walkways shall provide a direct and clear connection from the building’s main entrance to the transit stop/pedestrian drop off site. There are no transit stops or pedestrian drop off sites in the public right-of-way. Night lighting shall be provided where stairs, curbs, ramps, abrupt changes in walk direction, and cross vehicle lanes occur. Lighting must be ground-affixed lighting only the area of concern. Light poles are proposed in the vicinity of the public walkway across the driveway entrance. Canopy- and building-mounted lighting will also be placed at the stairs, curbs, and ramps at the main entrance to the building. A lighting plan has been provided as Sheet 6 of the Schematic Design, see Exhibit 3. Pedestrian drop off areas shall be designated by signage or markings and not be located near high volume travel lanes. There is no proposed pedestrian drop off area however there is a large island with sidewalk at the bend between side and rear parking areas. 7. Complexes totaling 100,000 square feet or more are required to provide a mass transit bus drop off/pick up area. Location of the bus service area shall be centrally located. A designated parking pull off from existing roadways to allow traffic to continue to move in a safe manner shall be provided. The parking area shall be next to a weather protected shelter/facility while customers wait for the bus service. This facility shall be located in a safe and well lit area. The roadway network shall be designed so that buses can maneuver easily and have clear view of bus stops and pedestrian walkways. The proposed facility shall also be built so that customers awaiting pick up can sit and see the bus arriving. The building will not total more than 100,000 square feet. No bus service area is proposed, and no designated parking pull off is needed for users of bus service. CODE OF THE TOWN OF CENTREVILLE, § 170, ATT. 6, § 4B (Sidewalk and Pedestrian) 1. Sidewalks shall be provided along all street frontages with appropriate connections to adjacent parcels and developments There is an existing concrete walk along the street frontage; an ADA compliant sidewalk is proposed on the south side of the entrance to connect the existing walk to the building through a marked crosswalk traversing a driveway and connects to a sidewalk on the southwest corner of the building. 6 All sidewalks must be installed using the requirements and specifications determined by the State Highway Administration (SHA). All sidewalks are to be installed in accordance with SHA requirements and specifications. See Site Plan, Site and Stormwater Management Profiles, at Exhibit 1. Any site work planned within State Roadways shall obtain approvals from the State Highway Administration (SHA). Any approvals from SHA will be obtained before permitting. Any new development or redevelopment shall provide for pedestrian connections between all internal commercial and residential uses. Internal commercial and residential uses are within the same building. There is a sidewalk beginning in the southwest corner of the building and continuing across the south and east sides of the building. See Schematic Design at Exhibit 3. Provisions shall be made to connect to future development and planned or existing sidewalks or pedestrian trails by dedication of easements for future connections. No future development is planned. There is an existing easement to a pedestrian trail. As discussed at preliminary site plan review, the proposed easement area provided satisfies the requirements of the Public Works Agreement in place with the Town and any approvals or review necessary for that easement, should it ever by utilized by the Town are in the purview of the Town Council. Crosswalks shall be required to create a visual and tactile connection between barrier free access curb ramps for the purpose of demarcation of appropriate pedestrian street-crossing locations in the following instances: At points of intersection between local residential streets or State maintained streets. At all signalized intersections adjoining the development site. At key locations to provide safe street crossing access to active or passive parkland and open space areas, schools, playgrounds, neighborhood shopping centers and similar pedestrian destinations within and adjoining the development The locations and criteria for curb ramps must meet SHA design and construction standards and the ADA Accessibility Guidelines for Buildings and Facilities (ADAAG) which gives requirements under the Americans with Disabilities Act (ADA) of 1990. Crosswalks that create visual and tactile connections between barrier-free access curb ramps and demarcate pedestrian street-crossing locations are located across the main entrance to the property and across an entrance driveway. The crosswalks will be appropriately marked with additional striping at the site entrance, which will align with detectable warning strips. The crosswalk at the site entrance will combine with the existing Commerce Street crosswalk. At the crosswalk at the main entrance, the curb will be sawcut for a smooth transition and an ADA compliant ramp will be made. An ADA compliant curb will also be made at the driveway crosswalk. See Site Plan, Site and Stormwater Management Profiles, at Exhibit 1. Sidewalks and trails shall be integrated with the overall landscaping design. The sidewalks and trails are integrated with the landscaping design. See Site Plan, Landscaping Plan, at Exhibit 1. 7 Pedestrian connections shall be clearly defined in a combination of 2 or more of the following ways: a trellis, special railing, bollards, and/or other architectural features to accent the walkway at key points. The walkways will be clearly defined through use of concrete, contours, markings, and other architectural features. Continuous landscape areas shall be a minimum of 3 feet wide on at least one side of the walkway, except as walkways cross vehicular travel lanes (where walkways abut a public right of-way and/or driving aisles, the landscape area shall be provided between the walkway and the public right-of way driving aisle). Continuous landscape areas that abut the walkways are at least 3 feet wide. See Site Plan, Landscaping Plan, at Exhibit 1. Pedestrian connections shall be reinforced with pedestrian scale lighting, bollard lighting, accent lighting or a combination thereof to aid in pedestrian way-finding. A light pole in the vicinity of the main entrance will keep the walkways lit, and accent lighting alongside the deck of the building will keep the sidewalks alongside the building additionally lit. Pedestrian walkways shall include clear sight lines to building entrances and should not be less than 5 feet wide. The pedestrian walkways have clear sight lines to the building entrances and are all at least five feet wide. CODE OF THE TOWN OF CENTREVILLE, § 170, ATT. 6, § 4C (Structures) 1. Visual prominence — the principal entry to the building shall be marked by at least one element from each of the following groups or any other combination of elements as approved by the Planning Commission: Group A (a) Recess (b) Overhang (c) Canopy (d) Portico (e) Porch Group B (a) Clerestory (b) Ornamental lighting fixtures (c) Large entry door(s) Group C (a) Stone, masonry or tile paving in entry (b) Ornamental building name or address (c) Pots or planters with flowers (d) Seating The two building entrances are marked with a large canopy that covers them and the abutting elevated walkways. The large storefront opening is marked with ornamental lighting fixtures and signs that display the ornamental building name. The street-facing façade has a prominent covered porch and large storefront glazing as well. 8 No permanent or non-permanent element that is attached to the principle building shall project or extend over the walkway with the exception of standards for inclement weather protection. The covered porch and canopy provide inclement weather protection and do not extend over the street. 2. Buildings shall have a distinct “base” at the ground level using articulation and materials, such as stone, masonry, or decorative concrete. Distinction may also occur through the following: (a) Windows (b) Architectural details (c) Canopies (d) Overhangs (e) Masonry strips and cornice lines The building has a distinct base created by large storefront windows, canopies, and numerous architectural details such as metal louvers that conceal the foundation piers. The northern façade has been revised to add additional metal paneling to break up monotony as requested by the Planning Commission at preliminary site plan review. The “top” of the building shall emphasize a distinct profile with elements such as projecting parapet, cornice, upper level step back, or pitched roofline. The top of the building is delineated and given a distinguishing profile by cornices; two stair towers, one of which is elevated, that extend from building; lines of windows; and the separating canopy and overhang. 3. Ground-floor, street-facing facades of commercial and mixed use buildings shall incorporate at least five of the following elements: (a) Medallions (b) Belt courses (c) Plinths or columns (d) Kickplate for storefront window (e) Projecting sills (f) Tilework (g) Pedestrian scale sign(s) or sign(s) professionally printed on windows (h) Planter box (i) Front porches or stoops (j) Water table line (k) Decorative panels (l) Any element not listed here that meets the intent, as approved by the Planning Commission Building facades not facing a street shall incorporate at least three of the above mentioned items. The building incorporates, at the ground level, belt courses, canopy columns, brick pilasters, projecting sills, porches, and decorative metal panels. 4. Structures greater than 30 or more feet in length facing streets or public areas including parking lots where windows are not provided shall have architectural treatment. At least four of the following elements shall be incorporated in the façade: (a) Masonry (b) Concrete or masonry plinth at the base of the wall (c) Belt courses of a different texture and color (d) Projecting cornice (e) Projecting canopy (f) Medallions 9 (g) Trellis containing planting (h) Decorative woodwork or tile work (i) Opaque or translucent glass (j) Artwork (k) Vertical articulation (l) Lighting standards (m) Recesses (n) Window walls (o) An architectural element not listed above that meets the intent, as approved by the Planning Commission The façade of the structure that lacks windows — which is necessary to provide a wall-length walk-in cooler in the store — does not face the street but is publicly visible. This façade was designed with masonry, is divided vertically with belt courses of different texture and color between the base and second floor, and features a projecting cornice. The façade further features bays that are accentuated with louvered openings and window recesses with projecting sills and heads that mimic the second-floor window openings to provide vertical articulation. Lastly, buffer planting is proposed along the boundary line on that side of the property. Common spaces shall be visible and/or accessible to the public. The proposed open areas of the site are unrestricted. 5. Plazas, courtyards and other pedestrian spaces shall include at least three of the following: (a) Special interest planting with a wide range of plant materials including perennials and flowering shrubs. Approximately 65% plant material used shall provide seasonal flower and/or foliage color. (b) Pedestrian scale, bollard, or other accent lighting (c) Special paving, such as colored/stained concrete, brick or other unit pavers. The use of low impact development materials, if appropriate to the site conditions, is encouraged. (d) Seating, such as benches, tables, or low seating walls (e) Water feature, such as fountain, etc. (f) Decorative trash receptacle (g) Bicycle racks An area with a picnic table and trash receptacle has been added on the southeast corner of the development site for use by residents and retail patrons. A bicycle rack and one or more decorative trash receptacles will also be provided adjacent to the southern façade of the proposed building. The applicant is, in response to comments by the Planning Commission, proposing a rooftop deck amenity for residential tenants. The rooftop deck will include easting and sitting areas and a grilling area. 6. Permanent site furnishings, such as benches, tables, and other pedestrian amenities shall be made of durable, weather-resistant and vandal-resistant materials. A picnic table, bicycle rack, and trash receptacle will be of durable, weather-resistant, and vandal-resistant materials. Permanent site furnishings shall be consistent with the overall character and appearance of the development. The proposed site furnishings would be incorporated into the overall design and landscaping of the development, as reflected on drawings and plans as appropriate. 10 Site furnishings shall not block pedestrian access to main walkways, open space areas and/or building entrances, bus or pedestrian loading, or drop off areas. The proposed site furnishings would not block pedestrian access to main walkways or the building entrances, and would be placed in a location reachable by but not intruding upon appropriate sidewalks. There is no proposed open space or area for bus or pedestrian loading or drop-off. 7. Buildings, along with trees and landscaping, shall be predominant rather than parking lots and free-standing signs. The parking lot must be placed in the rear and side of the building because of the irregular, elongated shape of the property. Such placement of the parking lot will help maintain forested areas of the property. Architectural design elements of the structure and robust landscaping plans will make the building and plantings predominant rather than the parking lots regardless of where the lots are placed. There is no proposal for free-standing signs. Pedestrian access to the building shall be visually and functionally clear and should offer a convenient alternative to walking through driveway entrances and exits. There is a sidewalk the entire length of the parking area, along with steps and ramps to an elevated walkway, that provides visually and functionally clear access to the building. Pavement markings will further direct pedestrians to the appropriate building access. 8. Setbacks: Encouraged Guidelines The streetside of the property is mostly adjacent to the entry driveway and there is no additional space there for a pedestrian area. 9. Overhead protection providing shelter from inclement weather at the main building entrance shall be required. Any method used to provide said protection shall be combined with the method used to achieve visual prominence. All the building entrances are covered with ample canopies that further achieve visual prominence and distinguish the base and top of the building. Where buildings are adjacent to a sidewalk, weather protection shall be provided. The minimum depth of any weather protection must be five feet (5’) unless limited by the building code. The vertical dimension between the underside of weather protection and the sidewalk must be at least 8 feet and no more than twelve feet (12’). Sidewalks, elevated walkways, and ramps, are protected from the weather by the canopies. The canopies will be at least 8 feet, and not more than 12 feet, above the sidewalks, walkways, and ramps. 10. Commercial buildings shall be designed to promote a pedestrian scale. To attain the continuation of a pedestrian scale, the use of sloping elements shall be required. Any alternative roofline not utilizing sloping elements must be approved by the Planning Commission. The approval of the Commission is sought for alternative means of achieving pedestrian scale. As currently designed, the roof is concealed with a parapet wall that is capped with an aluminum cornice trim above a solider course of brick, which is sufficient to continue pedestrian scale and fulfill the intent of the standard. 11. Mechanical equipment shall be screened from public areas by extended parapet walls or other roof forms that are integrated with the architecture of the building. 11 All outdoor mechanical equipment will be located on the roof and will be screened with a 5-foot-high parapet wall that is integrated with the architecture of the building. Because the property is in a floodway, the equipment cannot be located at grade. Communication equipment shall be blended in with the design of the roofs, rather than being merely attached to the roof deck. No communication equipment is proposed to be located on the roof of the building. Due to the nature and need for exposure of solar panels it may be difficult to conceal solar panel equipment. Should it not be possible to conceal the panel equipment, the location and placement of such equipment must be approved by the Planning Commission. No installation of solar panels is proposed. Painting mechanical equipment and erecting fences are not acceptable methods of screening. Screening of mechanical equipment shall be provided by the parapet wall rather than a fence, and there are no plans to paint the equipment. CODE OF THE TOWN OF CENTREVILLE, § 170, ATT. 6, § 4D (Lighting) Lighting design and layout have been provided in Sheet 6 of the Schematic Design, see Exhibit 3. 1. Pole-mounted fixtures in vehicular use or pedestrian areas shall not exceed a mounting height of 12 feet, and such poles shall be located so as not to be a hazard in the path of travel for pedestrian or vehicular access. The pole-mounted fixtures in vehicular-use or pedestrian areas will meet height requirements and be situated at driveways and on a curbed island to avoid posing a hazard in the path of travel for pedestrians or vehicles. All lighting shall be glare free and shielded from the sky (full cut-off) and adjacent residential properties and structures, either through exterior shields or through optics within the fixture. The proposed lighting will be glare-free and shielded from the sky and the second-story residential apartments. Safety lighting shall be provided at building entrance and doors sufficient to illuminate the doorway. Safety lighting will be mounted on the building near the entrance and doors. Outdoor lighting may exceed 12 feet in height if it meets one or more of the following criteria: Building mounted lighting directed back at a sign or building façade; or lighting on above- grade decks or balconies which shall be fully shielded. Additional lighting needed for highway or intersection safety as required by the State Highway Administration. Approved by the Planning Commission. Outdoor lighting will not exceed twelve feet (12’) in length. Lighting levels shall not exceed minimums established by the IESNA Recommended Practices and Design Guidelines Latest Edition and/or the American National Standards Institute (ANSI) and as necessary for safety. 12 The proposed lighting levels will meet safety minimums. 2. All lighting shall be glare-free and shielded from the sky and adjacent residential properties and structures, either through exterior shields or through optics within the fixture. The proposed lighting will be glare-free and shielded from the sky and the second-story residential apartments. Lighting shall not be used to attract attention to a business, but to provide reasonable levels of lighting for safety and identification. Proposed lighting is intended for safety and to sufficiently illuminate the name of the commercial enterprise and building for identification, not promotion, purposes. Lighting levels shall comply with Illuminating Engineering Society of North America’s Recommended Practices and Design Guidelines latest edition and/or the American National Standards Institute (ANSI) and as necessary for safety. The proposed lighting levels will meet safety minimums. Safety lighting shall be provided at building entrance and doors sufficient to illuminate the doorway. Safety lighting will be provided at the building entrance and doors. 3. Lighting styles of both poles and fixtures shall be of a style compatible with the design and architectural style of the buildings and facilities illuminated. Lighting fixtures shall be appropriate for the type of development proposed. As demonstrated in Schematic Design at Exhibit 3, the lighting fixtures and poles are appropriate for the design and architectural style of the building and site development. Pedestrian scale lighting shall also be accomplished with fixtures that are mounted on buildings or located to accent architectural or landscape features. Such fixtures shall be designed to enhance the overall architecture of the building, provide lighting for pedestrians and not damage historic materials. Pedestrian-scale lighting is to be accomplished in part with lighting that is mounted on the building and enhance the overall architecture. Prohibited Lighting Flashing lights — Any lights that flash, move, revolve, rotate, scintillate, blink, vary in intensity or color, or use intermittent electrical pulsation. Outdoor string of lights, including but not limited to those outlining lot lines, or outdoor display or sales lots as approved by the Planning Commission. Luminous colored tube lighting. The following lighting fixtures are prohibited in all new or re-development projects: o Cobra style fixtures o Open bottom fixtures o Mongoose fixtures o Other non-fully shielded fixtures Colored lighting unless specifically approved by the Planning Commission. 13 None of the types of prohibited lighting are proposed. The following lighting is exempt from lighting standards: (a) Holiday decorations (b) Construction or emergency lighting (c) Additional lighting needed for highway safety, and state approved traffic control devices (d) Industrial lighting shall be exempt from these standards; however, illumination from lighting on site shall not traverse or leave the site. Any use of the exempted lighting would be temporary, and no industrial lighting is proposed. CODE OF THE TOWN OF CENTREVILLE, § 170, ATT. 6, § 4E (Service Areas) 1. All service, loading and trash dumpsters areas shall be screened by a combination of masonry, wood, or vinyl walls and planting areas. The proposed trash area will be enclosed on three sides by a fence. The side used for service of the dumpsters will be enclosed with a gate. See Site Plan, Exhibit 1. Dumpsters shall be screened by walls, fences, gates and plantings and placed on a concrete pad. The dumpsters will be screened, have a gate, and be placed on a concrete pad. Loading and service areas shall not face any residential district, unless no other location is possible as deemed by the Planning Commission. The loading and service areas do not face any residential district. Loading areas shall be connected to the building or immediately adjacent to the building which the loading area services. The loading area is a delivery aisle that is immediately adjacent to the building. The pavement in that aisle can be striped to more clearly delineate it as a loading area. 14 Floodplain Narrative HILLSIDE LIQUORS AND DELI, LLC 2640 Centreville Road Centreville, MD 21617 Request: Approve a site plan pursuant to § 170-47 of the Code of the Town of Centreville, and, following approval, issue of a permit from for development or construction within the floodplain pursuant to § 66-14 of the Code. Introduction: The site is located at 425 S. Commerce Street, Centreville, Maryland 21617 (the “Property”) across Mill Stream from the existing Hillside Liquor store. The Property is designated as Tax Map 44B, Parcel 1085. Hillside Liquors and Deli, LLC (“Applicant”), proposes to construct a new commercial retail building with liquor store on the first floor and apartments on the second floor (the “Project”). The Project will have associated parking, pedestrian connectivity, landscaping, utility connections, and stormwater management. The Property is currently vacant and roughly stabilized in grasses with remnant gravel from historic uses. Mill Stream bounds the southwestern side of the subject Property. There are nontidal wetlands abutting the stream and are also present on the neighboring northern property with their associated 25-foot buffers. The rear of the site has wooded areas. The Property was rezoned to General Commercial C- 2 in 2015 pursuant to Town Council Ordinance 05-2015. The Property is in the Intensely Developed Area designation of the Chesapeake Bay Critical Area. The Property has a 100-foot stream buffer from Mill Stream but is mapped in the Buffer Modified Area (“BMA”). The Property used to have a large industrial and manufacturing building with a footprint of approximately 10,100 square feet. That structure was demolished pursuant to an agreement with the Town of Centreville. That preexisting site included the large building and surrounding impervious surfaces that extended to the bank of Mill Stream, making the Property eligible for redevelopment because it is mapped in the BMA. Prior to this application, a 16-unit condominium project was approved for this site. A portion of the property frontage was obtained by the State Highway Administration for right of way associated with Rt 213 bridge replacement. The site was also extensively used for staging when the State Highway Administration replaced that Rt 213 bridge spanning Mill Stream. The Property is located within the FEMA floodplain, zone AE area, and FEMA floodway. The existing floodplain mapping and floodway are modeled with the preexisting building included in that floodplain model. The base flood elevations across the existing open area of the Property range approximately from elevation 6.0 to 6.2 (NAVD88). Upstream portions of the Property have a base flood elevation of approximately 7.0 (NAVD88). This project began its planning in early 2022. Wetlands delineation and field survey were conducted. Preliminary architectural design commenced in early 2023. A joint permit application for wetlands disturbance was submitted to Maryland Department of the Environment (“MDE”) in March 2023. Per comments from MDE and coordination with the Town, a floodplain study was commissioned with Sustainable Science, LLC (“Sustainable Science”). Sustainable Science 1 conducted floodplain analysis based on the effective FEMA floodplain model, existing conditions survey data, and the proposed grading and building design. Proposed conditions floodplain analysis found that the proposed project does not cause a rise in the floodplain elevations. Phone and email coordination was conducted with the National Flood Insurance Program coordinator (the “NFIP Coordinator”) at MDE regarding whether the floodplain study was to normal modeling standards. The Applicant received a favorable response and recommendation to keep the MDE permit valid with inclusion of the floodplain “no-rise” study from Sustainable Science. The project was submitted for TAC review at its July 2024 meeting. Since that TAC meeting the Applicant and its representatives have met with staff, submitted to the Critical Area Commission and received comments, and reviewed and considered other comments and input provided by staff and Planning Commission representatives. The proposed building is designed, in accordance with floodplain and floodway considerations, to be on piers and well above the floodplain elevations. The proposed finished first floor elevation of the liquor store use is a 9.0 with floodplain elevations along the span of the proposed building in the 6.0-to-6.2 elevation range. All apartments are on the 2nd story. Only stairs and ramping will go to ground in addition to the piers. The site layout proposes to place the building along the northerly property line and setback to maximize distance from Mill Stream. Proposed parking is sited behind and to the side of the proposed building. Street site parking is available along Commerce Street approximately 100 yards north of the site in the event of a rare and extreme anticipated flood event. Permit Criteria: The criteria for issuance of a permit are set forth in Chapter 66, “Floodplain Management,” of the Code of the Town of Centreville. Each of the criteria are addressed as follows to demonstrate the compliance necessary for issuance of the permit. CODE OF THE TOWN OF CENTREVILLE, § 66-14 (Permits Required; And Expiration) A. It shall be unlawful for any person to begin any development or construction which is wholly within, partially within, or in contact with any flood hazard area establishing in § 66-5, including, but not limited to: filling; grading; construction of new structures; the substantial improvement of buildings or structures, including repair of substantial damage; placement or replacement of manufactured homes; erecting or installing a temporary structure, or alternation of a watercourse until a permit is obtained from the Town of Centreville. No such permit shall be issued until the requirements of these regulations have been met. Following approval of the site plan for the proposed development, the Applicant will apply for the permit to construct the building in the floodplain. No work will be performed in or out of the floodplain without first obtaining the permit. B. In addition to the permits required in Subsection A, applicants for permits in nontidal waters of the state are advised to contact MDE. Unless waived by MDE, pursuant to Code of Maryland Regulations 26.17.04, Construction on Nontidal Waters and Floodplains, MDE regulates the “one- hundred-year frequency floodplain of free-flowing waters,” also referred to as nontidal waters of the state. To determine the one-hundred-year frequency floodplain, hydrologic calculations are based on the ultimate development of the watershed, assuming existing zoning. The resulting flood hazard areas delineated using the results of such calculations may be different than the special 2 flood hazard areas established in § 66-5 of these regulations. A permit from Town of Centreville is still required in addition to any state requirements. Joint permit review has been sought from MDE to consider wetlands, stream, and floodplain disturbances within its jurisdiction. That permit application will continue to be pursued and processed, and it is understood that such MDE authorization must be obtained. C. A permit is valid provide the actual start of work is within 180 days of the date of permit issuance. Requests for extension shall be submitted in writing and justifiable cause demonstrated. The Floodplain Administrator may grant, in writing, one or more extensions of time, for additional periods not exceeding 90 days each, and provided there has been no amendment or revision to the basis for establishing special flood hazard areas and BFEs set forth in § 66-5. The Applicant will only engage in work with a valid permit and shall follow the established processes should any extensions be required. CODE OF THE TOWN OF CENTREVILLE, § 66-15 (Application Required) A. At a minimum, applications shall include: 1. Site plans drawn to scale showing the nature, location, dimensions, and existing and proposed topography of the area in question, and the location of existing and proposed structures, excavation, filing, storage of materials, drainage facilities, and other proposed activities. 2. Elevation of the existing natural ground where buildings or structures are proposed, referenced to the datum on the FIRMs. 3. Delineation of flood hazard areas, designated floodway boundaries, flood zones, base flood elevations, and flood protection setbacks. Base flood elevations shall be used to delineate the boundary of flood hazard areas and such delineations shall prevail over the boundary of SFHAs shown on FIRMs. 4. Where floodways are not delineated or base flood elevations are not shown on the FIRMs, the Floodplain Administration has the authority to require the applicant to use information provided by the Floodplain Administrator, information that is available from federal, state, or other sources, or to determine such information using accepted engineering practices or methods approved by the Floodplain Administrator. 5. Determination of the base flood elevations, for development proposals and subdivision proposals, each with at least five acres, whichever is the lesser, in special flood hazard areas where base flood elevations are not shown on the FIRM; if hydrologic and hydraulic engineering analyses are submitted, such analyses shall be performed in accordance with the requirements and specifications of MDE and FEMA. 6. Hydrologic and hydraulic engineering analyses for proposals in special flood hazard areas where FEMA has provided base flood elevations but has not delineated a floodway; such analyses shall demonstrate that the cumulative effect of proposed development, when combined with all other existing and anticipated development will not increase the water surface elevation of the base flood by more than one foot, or a lower increase if required by MDE. Please see the Site Plan for a Mixed Use Building in the Town of Centreville, Third Election District, Queen Anne’s County, Maryland (the “Site Plan”), attached hereto as Exhibit 1; the Stormwater Management Report, attached hereto as Exhibit 2; the Schematic Design, dated October 29, 2024 (the “Schematic Design”), attached hereto as Exhibit 3; and a flood study commissioned by the Applicant and previously provided to the Town (the “Flood Study”), attached hereto as Exhibit 4. The entire Property is within the 3 100-year floodplain but, as determined in the Flood Study, the proposed development results in no increase in the base flood elevation. 7. For encroachments in floodways, an evaluation of alternatives to such encroachments, including different uses of the site or portion of the site within the floodway, and minimization of such encroachment. The entire site is within the floodplain, and most of the site including the developable portion is within the floodway, and therefore encroachment cannot be avoided. The building is sited to maximize the distance from Mill Stream — it is farther from the stream than the previous building on the site — while maintaining necessary vehicular access. Further, the architecture and site engineering are designed and intended to minimize the risks and effects of the encroachment. For example, the building is elevated on piers and the site is graded to result in no increase in the base flood elevation. See Flood Study at Exhibit 4. 8. If fill is proposed to be placed for a purpose other than to elevate structures, the applicant shall indicate the intended purpose for the fill. No fill will be used to elevate structures. Elevating the building shall be achieved by piers to minimize obstruction of flood flow and result in no increase in the base flood elevation. 9. For proposed buildings and structures, including substantial improvement and repair of substantial damage, and placement and replacement of manufactured homes, including substantial improvement and repair or substantial damage: a. The proposed elevation of the lowest floor, including basement, referenced to the datum on the FIRM and a signed agreement to submit an elevation certificate. b. The signed declaration of land restriction (nonconversion agreement) that shall be recorded on the property deed prior to issuance of the certificate of occupancy, if the application includes an enclosure below the lowest floor or a crawl/underfloor space that is more than four feet in height. c. A written evaluation of alternative methods considered to elevate structures and manufactured homes, if the location is in nontidal waters of the state and fill is proposed to achieve the elevation required in § 66-34A or § 66-35A. Please see the Site Plan at Exhibit 1 and Schematic Design at Exhibit 3. There is no proposed enclosure below the lowest floor, nor a crawlspace or other underfloor area of more than four feet in height. The elevation of the structure will be achieved with piers to minimize obstruction of flood flow and result in no increase in the base flood elevation. 10. For accessory structures that are 300 square feet or larger in area (footprint) and that are below the base flood elevation, a variance is required as set forth in Article VII. If a variance is granted, a signed declaration of land restriction (Nonconversion Agreement) shall be recorded on the property deed prior to issuance of the certificate of occupancy. No accessory structures are proposed. 11. For temporary structures and temporary storage, specification of the duration of the temporary use. No temporary structures or temporary storage is proposed. 12. For proposed work on existing buildings, structure, and manufactured homes, including any improvement, addition, repairs, alterations, rehabilitation, or reconstruction, 4 sufficient information to determine if the work constitutes substantial improvement or repair of substantial damage, including but not limited to: a.

CODE OF THE TOWN OF CENTREVILLE, § 66-31 (General Requirements) In addition to the general requirements of Article IV the requirements of this section shall: A. Apply in flood hazard areas, including special flood hazard areas along nontidal waters of the state. B. Apply to all development, new construction, substantial improvements (including repair of substantial damage), and placement, replacement, and substantial improvement (including repair of substantial damage) of manufactured homes. The proposed development and construction will be designed to comply with both Articles IV and V. 10 CODE OF THE TOWN OF CENTREVILLE, § 66-32 (Flood Protection Setbacks) Within areas defined by flood protection setbacks along nontidal waters of the state: A. No new buildings, structures, or other development shall be permitted unless the applicant demonstrates that the site cannot be developed without such encroachment into the flood protection setback and the encroachment is the minimum necessary after consideration of varying other siting standards such as side, front, and back lot line setbacks. The entire site is within the floodplain and therefore encroachment cannot be avoided. To meet other applicable design and siting standards, and minimizing the effects of encroachment on nontidal waters, the building is sited to maximize distance from Mill Stream — it is further from the stream than the previous building on the Property — while maintaining vehicular access. The building will be elevated on piers and the site graded to result in no increase in the base flood elevation. B. Disturbance of natural vegetation shall be minimized and any disturbance allowed shall be vegetatively stabilized. Vegetative stabilization will be provided for during construction, and permanent stabilization will be provided at the completion of construction. The majority of the project is sited in open areas of the site that have historically been developed. Clearing will be kept to a minimum to provide the required parking and stormwater management. C. Public works and temporary construction may be permitted. The proposed development does not include public works or temporary construction. CODE OF THE TOWN OF CENTREVILLE, § 66-33 (Development That Affects Flood-Carrying Capacity of Nontidal Waters of the State) A. Development in designated floodways. 1. For proposed development that will encroach into a designated floodway, § 66-15A(7) requires the applicant to submit an evaluation of alternatives to such encroachment including different uses of the site or the portion of the site within the floodway, and minimization of such encroachment. This requirement does not apply to fences that do not block the flow of floodwaters or trap debris. The entire portion of the site that is open from wooded areas — which is the majority of the property — is within the floodway. As was the previous building on the site, the proposed building will be in the floodway. However, the proposed building will be elevated on piers to minimize the obstruction of flood flow and result in no increase in the base flood elevation. See Flood Study at Exhibit 4. The previous building was not elevated. 2. Proposed development in a designated floodway may be permitted only if: a. The applicant has been issued a permit by MDE; and b. The applicant has developed hydrologic and hydraulic engineering analyses and technical data prepared by a licensed professional engineer reflecting such changes, and the analyses, which shall be submitted to the Floodplain Administrator, demonstrate that the proposed activity will not result in any increase in the base flood elevation; or c. If the analyses demonstrate that the proposed activities will result in an increase in the base flood elevation, the applicant has obtained a Conditional Letter of Map Revision and a Letter of Map Revision from FEMA upon completion of the 11 project. Submittal requirements and fees shall be the responsibility of the applicant. The Applicant is currently making a joint permit application to MDE for the appropriate permitting. According to the Flood Study attached hereto as Exhibit 4, the proposed activity will not result in any increase in the base flood elevation. The Flood Study has previously been provided to the Town and will be submitted to MDE for review by the NFIP Coordinator. The previous building on the site had been included in the effective FEMA floodplain. B. For proposed development that includes the placement of fill in nontidal waters of the state, other than development that is subject to Subsection D, a hydraulically-equivalent volume of excavation is required. Such excavations shall be designed to drain freely. The proposed development elevates the building on piers to — as concluded in the Flood Study attached hereto as Exhibit 4, minimize obstruction of flood flow, mimic existing flood-carrying capacity, and result in no increase in the base flood elevation, such that current drainage shall be maintained. C. For development in special flood hazard areas of nontidal waters of the state with base flood elevations but no designated floodways: 1. The applicant shall develop hydrologic and hydraulic engineering analyses and technical data reflecting the proposed activity and shall submit such technical data to the Floodplain Administrator as required in § 66-15A(6). The analyses shall be prepared by a licensed professional engineer in a format required by FEMA for a conditional letter of map revision and a letter of map revision upon completion of the project. Submittal requirements and fees shall be the responsibility of the applicant. 2. The proposed development may be permitted if the applicant has received a permit by MDE and if the analyses demonstrate that the cumulative effect of the proposed development, when combined with all other existing and potential flood hazard area encroachments will not increase the base flood elevation more than one foot at any point. The Property is within a designated floodway. D. Construction of roads, bridges, culverts, dams and in-stream ponds in nontidal waters of the state shall not be approved unless they comply with this section and the applicant has received a permit from MDE. The proposed development does not include construction of roads, bridges, culverts, dams, or in-stream ponds. A permit is being sought from MDE for the entire project. E. Alteration of a watercourse. 1. For any proposed development that includes alteration of a watercourse not subject to Subsection C, unless waived by MDE, the applicant shall develop hydrologic and hydraulic engineering analyses and technical data reflecting such changes, including the floodway analysis required in § 66-15A, and submit such technical data to the Floodplain Administrator and to FEMA. The analyses shall be prepared by a licensed professional engineer in a format required by MDE and by FEMA for a conditional letter of map revision or letter of map revision. Submittal requirements and fees shall be the responsibility of the applicant. 2. Alteration of a watercourse may be permitted only upon submission, by the applicant, of the following: a. A description of the extent to which the watercourse will be altered or relocated; 12 b. A certification by a licensed professional engineer that the flood-carrying capacity of the watercourse will not be diminished; c. Evidence that adjacent communities, the U.S. Army Corps of Engineers, and MDE have been notified of the proposal, and evidence that such notifications have been submitted to FEMA; and d. Evidence that the applicant shall be responsible for providing the necessary maintenance for the altered or relocated portion of the watercourse so that its flood-carrying capacity will not be diminished. The Floodplain Administrator may require the applicant to enter into an agreement with the Town of Centreville specifying the maintenance responsibilities; if an agreement is required, the permit shall be conditioned to require that the agreement be recorded on the deed of the property which shall be binding on future owners. The proposed development does not include alteration of a watercourse. CODE OF THE TOWN OF CENTREVILLE, § 66-34 (Residential Structures and Residential Portions of Mixed Use Structures) A.

BOX 80 CENTREVILLE, MD 21617 DMS & ASSOCIATES JOB # 2022071 DATE: JUNE 2024 STORMWATER MANAGEMENT NARRATIVE FOR HILLSIDE The site is located at 425 S. Commerce Street, Centreville MD 21617 across Mill Stream from the existing Hillside Liquor store. The property is designated as Tax Map 44B, Parcel 1085. The property is currently vacant with poor soils roughly stabilized in grasses. Existing soils consist of Longmarsh and Indiantown soils of a hydrologic soil group “D” classification. The property is zoned C-2 and within the Intensely Developed Area (IDA) of the Chesapeake Bay Critical Area. The property is designated Buffer Modified Area (BMA). The property used to host a large industrial building that current owners demolished under agreement with the Town of Centreville. That preexisting site included the large industrial building and surrounding impervious surfaces that went right up to the top of the stream bank of Mill Stream. The property is located within the FEMA floodplain zone AE designation and floodway. The preexisting building and agreement with the town leaves the site grandfathered for redevelopment. The developer proposes to construct a new commercial retail building with liquor store on the first floor and apartments on the second floor. The building is designed with floodplain and floodway considerations to be on pilings and elevated. Only stairs and ramping will go to ground in addition to the pilings. The existing floodplain mapping and floodway are modeled with the preexisting building included in that floodplain model. The proposed building is substantially smaller in footprint than the preexisting building and will be elevated to a higher elevation. The site layout proposed the above mentioned building with associated parking, sidewalks, and other typical improvements. The project results in a limits of disturbance (LOD) of 1.299 acres and proposed impervious of 0.711 acres or 54.7%. Proposed grading will direct water in a similar fashion to existing drainage patters. Runoff for the site eventually will make it into Mill Stream. Stormwater management is designed to collect and treat the development’s new impervious area with Environmental Site Design (ESD) to the maximum extent possible (MEP) using new development criteria even though the site has historically hosted an industrial facility. The preexisting facility had no SWM treatment. The runoff from the proposed project will be collected, treated, and responsibly discharged to Mill Stream. Target ESD calculations have been prepared using the site imperviousness, soils, and LOD area. resulting in a site target rainfall (Pe) of 1.8”. The target ESD volume (ESDv) is 4,606 c.f. and target recharge volume of 179 c.f. Given the property is within the IDA designation of the Critical Area, the project must also address 10% pollutant reduction requirements. Using the calculation spread sheet provided by the Critical Area Commission, the target pollutant reduction is 1.14 lbs of Phosphorus per year (lbs P/yr). The project proposes to utilize a submerged gravel wetland (SGW) to provide ESD treatment to address SWM requirements. The proposed SGW is sited between the parking areas and Mill Stream to capture runoff and avoid direct discharge to the stream. The SGW will have two forebays for pretreatment that can overflow to a treatment cell. The treatment cell will have wetland soils, stone media, and an overflow inlet with controlling outfall pipe to provide the saturated environment needed for an SGW to property function. The volumetric combination of the forebays, treatment cell, and freeboard provide a total ESD volume of 9,423 c.f. The SGW is sized to address its respective drainage area, address the sites ESD and recharge requirements, and provide runoff storage and attenuation of even larger storm events and discharge it to Mill Stream. The SGW also provides a pollutant reduction of 1.23 lbs P/yr to address the IDA Critical Area pollutant reduction requirement. The proposed site design and SWM design address all SWM requirements.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

Commerce Street, Centreville, Maryland Prepared for: Davis, Moore, Shearon & Associates, LLC (DMS) FEMA Map Number: 24035C0212D I. Introduction This No‐Rise Certification is provided in compliance with the National Flood Insurance Program regulations. The following documentation supports the certification that the proposed project located at 425 S. Commerce Street, Town of Centreville, Queen Anne’s County, Maryland will not result in any increase in flood levels within the FEMA designated floodway. II. Description of the Proposed Work Project Purpose and Nature: The proposed project aims to develop a commercial retail liquor store with second‐floor apartments, including necessary access, parking areas, and other site improvements. The development is designed to enhance local commercial amenities while providing residential options, adhering to the Town of Centreville and Queen Anne's County floodplain ordinances and codes. The civil engineering site design is being performed by DMS, classified as job number 2022071. Project Location: The project site is located within the 100‐year floodplain and the floodway of the Mill Stream Branch. Specifically, it is located within cross‐section B of effective FIRM #24035C0212D. Specific attention has been given to the site's sensitivity to flood‐related impacts, ensuring compliance with local and federal regulations. Building Design and Construction: The main structure will be a commercial retail liquor store with second‐floor apartments. The building will be constructed on piers to elevate the finished floor to an elevation of 9.0 feet. This design is intended to place the structure 2 feet above the 100‐year floodplain elevation, which is at 7.0 feet.

Parking Lot and Site Improvements: The parking lot will be constructed close to the existing ground elevations to minimize the addition of fill within the floodplain. This approach is aimed at reducing potential impacts on the floodway's natural flow. Site improvements will include necessary utilities, stormwater management facilities, and access roads, designed to have minimal impact on the floodplain and floodway dynamics. Compliance with Regulations: The project will adhere strictly to all relevant local, state, and federal regulations governing construction and development within flood‐prone areas. This includes compliance with FEMA guidelines and the National Flood Insurance Program standards. III. Methodology Base Model Development The current effective 1‐dimensional HEC‐RAS model was used as the foundational tool for hydraulic analysis. The base model was updated to reflect existing conditions, particularly focusing on Cross Section B where the proposed work is taking place. A recent topographical survey, conducted by an external team, provided the necessary data to update Cross Section B. This survey ensured that the model would accurately represent the current physical conditions of the floodplain and floodway. Data Integration The updated base model incorporated the latest topographical data, ensuring that the analysis would be based on the most current and precise information available. This integration was crucial for establishing a reliable benchmark against which the impacts of the proposed project could be measured. Development of the Proposed Model A separate model, termed the 'proposed model', was created to incorporate the planned project features. The layout and grading details provided by DMS were used as the basis for including the proposed commercial retail liquor store, parking areas, and other site improvements in the model. The proposed model was designed to simulate how these new structures and alterations would interact with the existing floodway dynamics.

Commerce Street/Hillside - Mixed Use Building X FOR YOUR USE Introduction The Applicant seeks Final Site Plan Review (§170-22 A. (10) in accordance with the provisions of §170-47, especially §170-47 E.3 to “…approve, conditionally approve, or reject a site plan.” Staff recommends that the Planning Commission at a minimum review and discuss the issues identified in this memo along with any further follow up to previous Planning Commission issues identified through the Concept and this request for final site plan review consideration. The Planning Commission should work to establish findings of fact as you make any motions or decisions for approval, conditional approval of rejection of this site plan. The Concept Site Plan Review Application was reviewed by the Planning Commission at the October 16, 2024, Meeting, and Town of Centreville Technical Advisory Committee (TAC) on Monday, July 15, 2024. The site plan at 425 S. Commerce Street is a proposed Mixed-Use Development of an approximately 12,712 square foot 2 story building. The first-floor retail use (liquor store) is approximately 6,356 square feet and the second floor consists of six two-bedroom apartment units in 6,356 square feet. Currently, this property is proposed for a Future Land Use Map Amendment to redesignate the Future Land Use from Resource, Conservation and Open Space to Commercial. It is currently under State and Local review, with comments expected mid to late December 2024. Future public hearings for consideration of this proposed amendment are anticipated to be held in early 2025. Issues Please refer to the October 16, 2024, Site Plan Concept Review Memo dated October 11, 2024, for background. 1 1. Trail Easement – PWA Agreement – update or modification of the Public Works Agreement regarding the trail easement still needs to be addressed. As reviewed by TAC July 2024 and Planning Commission October 2024 during Concept Site Plan, this site was the subject of two Public Works agreements and a rezoning approved by the Town of Centreville. The 2009 PWA establishes a fifteen-foot trail easement, noted in Ordinance 05-2015. Currently, this trail easement is still in effect. The Millstream trail extension is also included in the Town of Centreville’s Greenway and Trail Plan in the Town of Centreville Comprehensive Plan: 2040. 2. Entrance design and standards – While the updated entrance design may provide for improved access than originally proposed, the proposed entrance was discussed by Planning Commission with the applicant during Concept review at the October 16, 2024, meeting. Prior review comments notified the applicant, and they acknowledged that coordination and review is required with MDOT SHA. No additional information has been provided, other than a response (several 8/16/24 TAC responses included in October Concept Review Documents) that they will coordinate with MDOT SHA District 2, referring in several places about obtaining SHA permits after final site plan approval. From Applicant’s August 2024 submittal (October 2024 Planning Commission Concept review documents) “TAC Comment: 10. Sheet C‐3. I recommend modifying the entrance to a monumental split (see photo sketch attached) this provides the required entrance width on Commerce, takes unneeded impervious asphalt cover out, allows the project “one‐way directional sign” (note 17) to be moved to a more readable place…” Applicant Response: “We have added a monumental entrance with area of depressed curb that will host a one-way directional sign.” 3. Mitigation – Modified Buffer Area – This application is subject to required mitigation re the Modified Buffer Area as identified by TAC, Planning and Critical Area Commission Staff. Critical Area Commission staff recently provided this confirmation for Planning Commission and Town’s consideration: Mitigation is required per the Town of Centreville's Critical Area Program: https://centreville.municipalcodeonline.com/book?type=ordinances#name=170- 31.13_Buffer_Management_Area_(BMA)_Provisions 4. Parking and Permeable surfaces- Site Plan Review process issues re Stormwater (County Stormwater Review) - The applicant proposes a reduction in square footage considered for parking due to “storage as well as the exclusion of a stairwell from the square footage.” Research 2 on parking rates for an approved site plan in Centreville (2016) with storage (of sales inventory) was based on total square footage of the building. • While reduced amount of parking/pervious surface in this location (floodplain/ IDA Critical Area Modified Buffer area) may be appropriate, the parking area should considered be porous or permeable surface to help further facilitate stormwater goals, significantly reduce the amount of impervious cover, provide water quality and groundwater recharge benefits. • The Planning Commission discussed concern for dedicated parking for the apartments and may wish to ensure that dedicated parking is signed noticed and available to residents. o Reduction in Required Parking – Reduction of six spaces. ▪ Reduction requested – from 39 required spaces to 33. • Parking Standards (Gross Square feet of floor area) o The Apartments: the §170-32(A) standard of 2.25 spaces each for 2- bedroom apartments (6) which equals 13.5 spaces (application notes 13). o Retail Liquor Store §170-32(A) is 1 space per 250 square feet. o Based on the §170-32(A) standard using gross square feet of floor area, 6,356 square feet ÷ 250 = 25.4 spaces o Assuming the 2 ADA spaces noted are required as well, the parking provided on the site should be 40.9 (13.5 (apartments) + 25.4 (retail) + 2 ADA) or 39 (without the ADA spaces) ▪ The application utilizes only 6,048 of ground floor square footage (versus 6,356) reduced by 308 square feet of stairwell and seeks to allow the modification of parking to be reduced for 1,344 square feet of retail to provide for the storage areas within the liquor store requiring only 19 spaces for the ground floor (reduction from 39 spaces overall to 33, reduction of approximately 6 spaces). ▪ Pervious – permeable surfaces • Centreville Code 170-32 D. 4 -Off Street Parking: Design standards for parking areas. “Parking areas associated with public, semipublic, commercial, or industrial uses and residential structures with more than two units shall be surfaced and maintained with a paved material in conformity with Town 3 Design Specifications to form a durable surface. Use of porous or permeable paving is encouraged to achieve stormwater management goals.” • From a recent share from Critical Area Commission Staff: Pervious Pavers: We support the consideration and use of alternative surfaces. Per the MDE Stormwater Design Manual, "An effective method to reduce imperviousness in residential, commercial, and industrial applications is to use more permeable alternatives." Example shared from CAC below re MDE Stormwater Design Manual items regarding Permeable pavers, pervious concrete, or reinforced grass pavement: Link: MDE Stormwater Design Manual Site Plan Review process issues re permeable surface Stormwater (County Stormwater Review) o Queen Annes County (QAC) Department of Public Works (DPW) provided the following regarding permeable surfaces: QAC DPW prefers the use of permeable pavers or permeable concrete surfaces and discourages the use of permeable asphalt. For any infiltration practice, we recommend a site-specific geotechnical investigation be performed as part of the design. In this specific case, permeable pavements may not be suitable, however until infiltration testing is performed it is 4 still unknown. DPW also noted (see comment below re stormwater) that considers their application as “preliminary” as “the plans are still in a preliminary design phase and many of the technical comments made will be addressed by the consultant when the plan moves to the final site plan phase.” o Town Engineer Whitehill provided the following: “…the soils on site may not be conducive at all to under-draining pervious surfaces. The MSHA work gave us an opportunity to see those soils when installing sewer and water trenches and the jack and bore pit. When the soils do not drain, the permeable portions get clogged and provide no benefit for water quality.” o Additionally, QAC Planning, in their review of site plans that involve the implementation of 10% water quality improvement requirements for CA IDA projects, defers to DPW on appropriate implementation of such suggested BMPs. Together, County plan reviewers would talk through the site conditions (soil, water table, drainage, and so on) and explore the appropriate SWM maintenance agreements. 5. Stormwater potential for pollution of Millstream – Planning Commission should consider this important review in the consideration of this site plan final approval request. QAC DPW staff Eric Miller provided the following “Based on my initial (and only) comment memo dated July 12, 2024 and the response memo you provided from DMS dated August 16, 2024 the plans are still in a preliminary design phase and many of the technical comments I made will be addressed by the consultant when the plan moves to the final site plan phase.” From the September 16, 2024 Critical Area Commission staff memo, Town of Centreville asked the applicant to address the Stormwater issue raised by CAC staff, regarding the location and the vulnerability of the site, it appears likely that the SGW, including the forebays, will be flooded during storm events and could potentially export pollutants to Mill Stream. CAC Staff updated comment re Stormwater management: Our letter notes the location of the SWM BMP in the floodplain/floodway and asks if alternative locations were considered to reduce vulnerability to flooding and to ensure that the facility continues to function as designed. Ultimately, the SWM plan is reviewed/approved by the Town of Centreville. The Applicant replied verbally and now in written response: “The project proposes to utilize a submerged gravel wetland (SGW) to provide ESD treatment to address SWM requirements. The proposed SGW is sited between the parking areas and Mill Stream to capture runoff and avoid direct discharge to the stream. The SGW will have two forebays for pretreatment that can overflow to a treatment cell. The treatment cell will have wetland soils, stone media, and 5 an overflow inlet with controlling outfall pipe to provide the saturated environment needed for an SGW to property function. The volumetric combination of the forebays, treatment cell, and freeboard provide a total ESD volume of 9,423 c.f. The SGW is sized to address its respective drainage area, address the sites ESD and recharge requirements, and provide runoff storage and attenuation of even larger storm events and discharge it to Mill Stream.
