61 Marine & Sports — Expansion of Non -Conforming Uses
December 17, 2018
Proposal
61 Marine & Sports located at 11730 Point Douglas Drive South is requesting a conditional use
permit (CUP) to expand the existing nonconforming use of indoor and outdoor sales of recrea-
tional vehicles and equipment to allow for additional outdoor storage and sales of recreational
vehicles and boats on a leased plot of land that is 2 acres in size and is located adjacent to and
directly to the east of the existing facility. Access to the site is via State Highway 10/61. A detail
of the expansion area is identified in yellow below.

Location Map 2018 Proposed Expansion Area
Background
An expansion of a service building on the site was approved by City Council on October 17,
2018 (Resolution 2018-130).
The site currently has a variety of outdoor storage areas, sales and service buildings, and a
large surface water management pond. Expansions on the site were completed over the years,
which required CUP amendments for the expansion of the non -conforming uses. It should be
noted that the City Council Resolution 2015-118 that approved a 2015 CUP amendment re-
quires that any additional building construction or site improvements must meet the City's
Zoning Ordinance performance standards for site development. The current proposed parking
construction materials and design does not meet the referenced City's Zoning Ordinance
performance standards for site development.

Planning Considerations
Land Use and Zoning
The applicant's property and the proposed expansion property are both guided for Commercial
in the 2030 and 2040 comprehensive plans and are zoned B-2, Retail Business. The existing
indoor and outdoor sales of recreational vehicles is a non -conforming use in the B-2 Zoning
District and requires a CUP for the expansion of a non -conforming use.

Conditional Use
The applicant currently sells and services recreational vehicles, boats, motors, trailers, and re-
lated equipment and parts. This use is conducted inside and outside of buildings on the site.
The applicant wishes to expand the existing exterior storage yard, which was last expanded in
2015.

Ordinance Criteria
When reviewing CUP applications, the Planning Commission must review the application for
conformance with the following criteria established by City code: Title 11-2-9F.
Title 11-2-9F Criteria For Issuance Of Permit:
1. The use will be in conformity with the City's Comprehensive Plan and with the purpose, intent
and applicable standards of this Title.
2. The use shall be located, designed, maintained and operated to be compatible with the existing
or intended character of that zoning district in which it is located.
3. The use shall not depreciate values of surrounding property.
4. The use shall not be hazardous, detrimental or disturbing to present and potential surrounding
land uses due to noises, glare, smoke, dust, odor, fumes, water pollution, vibration, general
unsightliness or other nuisances.
5. The use shall generate only minimal vehicular traffic on local streets as defined by the trans-
portation element of the Comprehensive Plan. The use shall not create traffic congestion,
unsafe access or parking needs that will cause inconveniences to the adjoining properties.
6. The use shall be served adequately by essential public services, such as streets, police, fire
protection and utilities.
7. The use shall not create excessive additional requirements at public cost for public facilities
and services and shall not be detrimental to the economic welfare of the City.
Planning Staff Report — Planning Case No. CUP18-051
61 Marine & Sports Expansion of Non -Conforming Use
December 17, 2018
Page 4 of 7
8. The use shall preserve and incorporate the site's important natural and scenic features into the
development design.
9. The use shall cause minimal adverse environmental effects.
10. The use shall not adversely affect the potential development of adjacent vacant land.
The City's Technical Review Committee reviewed the application based on the above. None of
the attending City Department representatives had any comments or recommendations for the
application.
Minor Subdivision
The proposed expansion area is located on leased property not owned by the applicant. Fee
title acquisition of the leased area will require a minor subdivision application to be processed
before the City prior to release of a deed for recording the deed with Washington County.
Site Plan
The area highlighted in yellow is the proposed site expansion location. The improvements to the
site include ponding and storage/parking areas. Prior to the item going before the City Council, a
revised site plan must be submitted that details required setbacks, landscaping, approved pond-
ing, and parking/storage locations.

Architecture
There are no buildings proposed for construction within the proposed expansion area or existing
site.
Access
The access to the site will not require modification to the site for the addition of the new storage
area, and no additional traffic generation that is negative to the site or adjacent highway is antic-
ipated.
Parking
The proposed expansion area does not require additional parking on the site. The surface of the
expansion area is proposed to be finished with reclaimed bituminous material consistent with
material approved for the site with the two previous Council approved expansions.
Grading and Stormwater Management
Grading in the propose expansion area was recently completed without a grading permit. Based
on this action, a grading permit must be obtained, and the issuance fee shall be doubled.
The applicant's engineer has submitted a surface water management report for the site. The fi-
nal surface water calculations and grading modifications will need to be reviewed and approved
by the City Engineer. The final grading plan and site grading of the property must be consistent
with the approved plan.

Setbacks
The existing ordinance criteria requires a 10 -foot wide side yard setback area from side property
lines for parking and drive aisles. These setback areas are typically landscaped as a component
of required landscaping and screening site performance standards. It is recommended that this
requirement be reiterated in the listed conditions related to this CUP amendment.
Fencing
The applicant is proposing to relocate the existing perimeter fence to the new expansion area.
Tree Preservation
The trees on the site were removed by the current property owner as a component of the ongo-
ing agricultural use of the site. There is no tree removal proposed with this application.
Landscaping
There are no landscaping modifications planned for the proposed expansion.
Summary
• The site does not meet current site development and landscaping standards.
• Grading in the requested expansion area was recently completed without a grading permit.
• The operation of the current nonconforming use on the site has been conducted without any
negative consequences, and the proposed expansion is expected to operate in the same
fashion.
• The proposed commercial expansion is consistent with the designated land use.
• The proposed commercial expansion has been found to be consistent with the balance of
the criteria for issuing a conditional use permit.
Recommendation
That the Planning Commission recommends that the City Council approve a conditional use
permit to expand the existing nonconforming use of indoor and outdoor sales of recreational ve-
hicles and equipment to allow for additional outdoor storage and sales of recreational vehicles
and boats on a leased plot of land that is two acres in size, subject to the following conditions:
1) All conditions of Resolution 2015-118 and Resolution 2018-130 shall be conformed with.
2) A grading permit must be obtained by January 4, 2019, and the issuance fee shall be
doubled.
3) A 10 -foot wide side yard setback area from the east side property line shall be required
for parking and drive aisles.
4) Maintain 20 -foot fire access lanes between boats, vehicles, and equipment.

5) Landscaping and screening shall be included in the required setback areas. A revised
landscaping plan shall be submitted to the City prior to the application being placed on a
City Council agenda.
6) A revised site plan which details required setbacks, landscaping, approved ponding, and
parking/storage locations is required prior to the item being placed on the City Council
agenda.
7) All applicable permits (i.e.; building, electrical, grading, mechanical, right-of-way) must be
completed, submitted, and approved by the City prior to the commencement of any
construction activities. Detailed construction plans must be reviewed and approved by the
Building Official and City Engineer.
8) Prior to the release of the grading permit, a bona fide cost estimate of the landscaping im-
provements must be submitted in conjunction with a letter of credit approved by the City in
the amount of 150 percent of such estimate. Upon completion of the landscaping require-
ments, the applicant must inform the City in writing that said improvements have been com-
pleted. The City will retain the financial guarantee for a period of one year from the date of
notice of completion to insure the survival of the plantings and that the required as -built sur-
vey has been submitted. No building or right -of way permits will be issued until the required
financial guarantee has been received and accepted by the City.
9) Landscaping on the site must be maintained in good health at all times, and dead plantings
shall be replaced in a timely manner.
10) Address all comments in the Bolton & Menk letter dated December 6, 2018.
11) Fee title acquisition of the leased area will require a minor subdivision application to be
processed by the City prior to release of a deed for recording with Washington County.

MEMORANDUM
Date: December 6, 2018

From: Brent Johnson, PE
Subject: 61 Marine & Sports, East Storage Lot Expansion Development
City of Cottage Grove
Project No.: N14.117813

A civil and site design package submittal for 61 Marine & Sports, East Storage Lot Expansion (October 30,
2018) including Civil and Site Design Plan Sheets 1 through 7 of 7; Stormwater Management Plan
Narrative for East Storage Lot Expansion (dated October 30, 2018), and Hydro CAD reports for Existing
and Proposed Conditions (10-30-2018) submitted by Emmons & Olivier Resources, Inc. The following
comments relating to stormwater are provided:
1. The applicant will need to execute a stormwater maintenance agreement with the City related to
the new stormwater BMPs that will be constructed.
2. Volume Control
a. Two infiltration basins are proposed on the site. One existing infiltration basin is to be
reconstructed on site and one new infiltration basin will be built.
b. The project site is not located within a Drinking Water Supply Management Area
(DWSMA) so infiltration appears to be allowable provided it is not prohibited by other
constraints such as depth to bedrock or water table or potential hotspots.
The City and Watershed District require soil borings in the vicinity of proposed volume
control BMPs. The NPDES Construction Stormwater permit also requires that:
"...Permittees must provide at least one soil boring, test pit or infiltrometer test in the
location of the infiltration practice for determining infiltration rates. " Borings are
needed to identify soil conditions and the presence of groundwater or bedrock. Soil
borings should extend a minimum of 3 feet below the lowest constructed elevation of
proposed BMPs. The applicant used an infiltration rate of 0.3 inches per hour for both
the new infiltration basin and the reconstructed basin in the HydroCAD models, this
value needs to be verified once the soil borings are available.
d. The City requires adequate pretreatment of stormwater runoff from development and
redevelopment activities prior to discharge into all waterbodies. Grassed side slopes are
shown in the plans for pretreatment of the infiltration basins. The existing and
proposed gravel parking lots are intended to sheet flow to the infiltration basins. It
seems likely that runoff may be concentrated and erosive as it flows into the basins.
Dedicating part of the basins to a pretreatment sediment basin seems like a better
method of pretreatment and a more long-term solution. Please change the infiltration

basin plans to include pretreatment cells or explain how the turf slope will provide a
long-term pretreatment solution.
e. The City requires runoff volume control for new development equal to 1 -inch of runoff
from new impervious surfaces. 0.6 acres of existing impervious surfaces drain to the
South basin. An additional 1 acres of new impervious surfaces will drain to the South
basin and 0.51 acres of new impervious surfaces will drain to the North Basin.

The proposed void space volume of the North and South Basins are 3935 cubic feet and
7124 cubic feet, respectively; with a combined void space volume of 11,059 cubic feet. This
proposed infiltration volume exceeds the volume control requirement. The design
infiltration rate of 0.3 inches per hour needs to be verified with the soils borings. The basin
designs include a 48-hour drawdown time.
The infiltration basins include a 3 -foot thickness of soil media with a composition listed as 20%
MNDOT Grade 2 Compost, 80% Coarse Washed Sand. For a more successful vegetation
establishment, the City recommends providing a Filter Topsoil Borrow (MnDOT 3877.2G)
consisting of 70% sand (meeting the gradation requirements of 3126 "Fine Aggregate for
Portland Cement Concrete") and 30% Grade 2 Compost (MnDOT 3890).
4. Stormwater Modeling: A HydroCAD model was prepared of existing and proposed conditions.
a. The HydroCAD model does not include the existing infiltration basin within the Existing
Conditions model. Please include the existing basin in the model, or explain why it is
not included.
b. Atlas 14 precipitation depths were used in the analyses. The precipitation depth used
for the 100 -year analyses is 7.2 inches. This value is lower than the Atlas 14 100 -year
value of 7.4 inches in 24 hours. Please correct the HydroCAD models for the 100 -year
precipitation depth.
c. The HydroCAD model includes existing conditions pervious area curve numbers (based
on HSG B) of 65 and 78 for Woods/Grass and Row Crops. These values are higher than
the acceptable range of the South Washington Watershed District, so please correct
the curve numbers in the model. The South Washington Watershed District Standards
Manual specifies: "For predevelopment conditions, the allowable range for a CN to
reflect undeveloped conditions should fall within values of 52 — 62 and must not exceed a

value of 62." Please adjust the existing conditions curve numbers to comply with the
watershed standards.
5. Rate Control.
a. The HydroCAD model and stormwater narrative indicate that rate control is met and
the peak flow rates after development do not exceed pre -development peak flow rates
for the critical 1 -year, 2 -year, 10 -year, and 100 -year recurrence interval precipitation
events.
6. The Stormwater Management Plan Narrative indicates that the infiltration BMPs will remove a
minimum 80% TSS and 50 %Total Phosphorus prior to leaving the site. Please document the
water quality treatment provided within a water quality model such as P8 or MIDS.
a. Include in the water quality narrative a discussion of whether the total phosphorus load
meets the Watershed allowable rate of 0.22 lbs./acre/year for drainages to the
Mississippi River or existing loading rates, whichever is less.
7. Freeboard standards: For stormwater facilities with emergency overflows, the low entry
elevation for all structures must be a minimum of 3 feet above both the peak surface water
elevation for the 100 -year precipitation event and 2 feet above the emergency overflow
elevation of any immediately adjacent new stormwater basin. Please include a description of
the low entry elevations for on-site structures in relation to the expected high-water elevations
and emergency overflows and show the building low entry elevations on the plans.
8. Basin outlet structure: The plan sheets 3 and 5 show the North infiltration basin with an Agri -
Drain water level control structure. Please provide drawing details of this proposed outlet
control structure.
9. NPDES Construction Stormwater Permit: As this project disturbs more than 1 acre, an NPDES
Construction Stormwater Permit and SWPPP will be required.
