Planting Utility
2. Staff previously commented (#8) on the use of clump trees in the right-of-way and recommended large maturing
shade trees. The proposed Pyramidal Hornbeam is not acceptable street tree and shall be revised per one of the
approved street trees in Chapter 3 of the Design and Construction Standards large maturing tree category. Note
again the Ash is not acceptable. An Elm variety, any of the approved Oaks, Hackberry or an alternative as approved
by staff may be specified.
3. Staff previously commented (#2) that the grading plan did not protect the existing Pine on Aurora. Although a wall
may be a reasonable way to accommodate for the proposed grading around the tree, it may not be located as
currently shown. Relocate the wall to the outside edge of the tree's dripline or revise the proposed grading to eliminate
the need for a wall entirely. If a wall is needed, include the Design and Construction Standard Detail 3.04 Grade
Change Around Existing Trees on the plans.
4. Update the plan on sheet A8, Open Areas, to accurately reflect the stair alignment on Aurora and current site layout.

III. INFORMATIONAL COMMENTS
Drainage (Steve Buckbee, 303-441-3279)
1. Drainage easements are required over the detention ponds and in a width of 10 feet to connect the ponds to other
easements and right-of-way in cases where a pond is not located directly adjacent to city right-of-way or easement.
2. The location of the detention pond directly adjacent to the north foundation wall requires a letter from the structural
and/or soils engineer indicating that water storage and infiltration next to the foundation will not present any structural
problems. An engineer stamped copy of the letter provided will be required before the final engineering plans can be
Address: 900 28TH ST
approved. Additionally, the letter will need to address the wet soil conditions that the detention pond will create next to
the foundation. Any proposed foundation drain or water proofing systems will need to be finalized and included with
the technical document submittal.
3. Provide an engineer stamped copy of the soils report with the technical document submittal.
4. A construction storm water discharge permit is required from the State of Colorado for projects disturbing greater than
1 acre. The applicant is advised to contact the Colorado Department of Public Health and Environment.

Engineering (Steve Buckbee, 303-44'1-3279)
The applicant is notified that any groundwater discharge to the storm sewer system will require both a state permit and a
city agreement. The steps for obtaining the proper approvals are as follows:
Step 1 Identify applicable Colorado Discharge Permit System requirements for the site.
Step 2 Determine any history of site contamination (underground storage tanks, groundwater contamination,
industrial activities, landfills, etc.) If there is contamination on the site or in the groundwater, water quality
monitoring is required.
Step 3 Submit a written request to the city to use the municipal separate storm sewer system (MS4). This submittal
should include a copy of the Colorado Department of Public Health and Environment (CDPHE) permit
application. The written request should include the location, description of the discharge, and brief
discussion of all discharge options (e.g., discharge to MS4, groundwater infiltration, off-site disposal, etc.)
The request should be addressed to: City of Boulder, Stormwater Quality, 4049 75th St, Boulder, CO 80301
Fax: 303-413-7364
Step 4 The city's Stormwater Quality Office will respond with a DRAFT agreement, which will need to be submitted
with the CDPHE permit application. CDPHE will not finalize the discharge permit without permission from
the city to use the MS4.
Step 5 Submit a copy of the final discharge permit issued by CDPHE back to the City's Stormwater Quality Office so
that the MS4 agreement can be finalized.
For further information regarding stormwater quality within the City of Boulder contact the City's Stormwater Quality
Office at 303-413-7350. All applicable permits must be in place prior to building permit application.
Utilities (Steve Buckbee, 303-441-3279)
1. The private sewer service and associated easement serving 910 28th must be abandoned before this final engineering
can be approved.
2. The applicant is advised that any proposed street trees along the property frontage may conflict with existing utilities,
including without limitation: gas, electric, and telecommunications, within and adjacent to the development site. It is
the applicant's responsibility to resolve such conflicts with appropriate methods conforming to the Boulder Revised
Code 1981, the City of Boulder Design and Construction Standards, and any private/franchise utility specifications.
3. Maintenance of sand/oil interceptors and all private wastewater and storm sewer lines and structures shall remain the
responsibility of the owner.
4. Floor drains internal to covered parking structures, that collect drainage from rain and ice drippings from parked cars
or water used to wash-down internal floors, shall be connected to the wastewater service using appropriate grease
and sediment traps.
5. All water meters are to be placed in city R.O.W. or a public utility easement, but meters are not to be placed in
driveways, sidewalks or behind fences.
6. Trees proposed to be planted shall be located at least 10 feet away from existing or future utility mains and services.
