Conclusion:
2017-2018
No development cases have been filed in opposition to pertinent construction ordinances, and ordinance has supported all upheld enforcement cases.  No reasons exist to update ordinance.



4.2: Stormwater Enforcement
Year Executed: 2011
Reference Regulation:
4.2.4.2, 4.2.4.2.1, 4.2.4.2.2
Target Pollutants:
Sediment, fugitive dust, cementitious material, trash, non-stormwater liquids, and nutrients.
Audiences:
Developers, Engineers, Architects, Contractors and MS4 Staff
Description:
Land Disturbance and Long-Term Stormwater Management activity is regulated by Riverton City Code Title 13.  The LDP Penalty and Fine Schedule below only applies to Land disturbance permit regulated activity.  Stormwater are also regulated by Titles; 8, 12, 15, 17 and 18 but to a lesser degree.  Generally, enforcement regulated by these Titles are managed by the Ordinance Enforcement Division.
Measure of Success:
Annually evaluate the issues related to program enforcement.  Make conclusions and recommendations to City.
Responsible Staff:
Public Works Director, City Engineer, Stormwater Manager, Stormwater Inspector, Ordinance Enforcement
Funding:  
Stormwater Utility, General Fund
Program Documents: 
Documentation:
Land Disturbance Permit Summary Report
Individual Land Disturbance Permit files also contain pertinate enforcement documentation.  These can be requested.
Conclusion:
2017-2018
Previous years including half of this report period stormwater enforcement primarily invoved Building Department holds and NOV's received less support.  This method had moderate success however, response to compliance was often inadequate.  NOV's use has received more support the later half of this period and the Stormwater Division personnel feels NOV application will improve compliance but it is still a little to soon to show a measure of program improvement.    
The Land Disturbance permit Summary Report contains the support data.
 

4.3: Land Disturbance Permit
Year Executed: 2011
Amended: 2015-09-29
Reference Regulation:
4.2.4.3, 4.2.4.3.1, 4.2.4.3.2, 4.2.4.3.3, 4.2.4.3.4, 4.2.4.4, 4.2.4.4.1, 4.2.4.4.2, 4.2.4.4.3, 4.2.4.4.4, 4.2.4.5, 4.2.4.6, 4.2.6.8
Target Pollutants:
Sediment, fugitive dust, cementitious material, trash, non-stormwater liquids, and nutrients.
Audiences:
Developers, Engineers, Architects, Planners, Contractors and MS4 Staff
Description:
The Land Disturbance Permit (LDP) program involves a traditional permitting process using a permit application form as its vehicle for creating a contractual relationship and establishing terms and conditions.  A LDP is required prior to any qualifying land disturbance.  The primary LDP application submittal requirement is the SWPPP and facilitates:
    1. A SWPPP review process resulting in a complete and coherent SWPPP prior to issuance.  
    2. Requires the SWPPP to be managed via an internet based system. 
    3. Ensures that the SWPPP is always available to all involved in the project, including Operators, their staff, subcontractors, suppliers, utility companies, MS4, EPA and the general public upon request.
    4. Requires other terms and conditions that are required by City ordinance that are not directly required by the GCP, CPoD and MS4 regulation.
There are four SWPPP templates written for the expected construction applications. These are; projects that are 1Acre and larger, residential Common Plans of Development, NOI Exempt Projects and Short Term Projects.
Measure of Success:
Success can be measured by reducing the number of public complaints pertaining to Land Disturbance Projects relative to the number of active Land Disturbance Permits.  When LDP enforcement actions are high and public complaints are low, the enforcement program can be viewed as successful.  However, when enforcement actions are low and public complaints are low then the Land Disturbance Program can be viewed as successfull because it has changed or controlled permit holders behavior which is a true measure of a successful Land Disturbance Permit Program.
Record the number of permits issued for the report period.
Record the number of enforcement actions for the report period.
Record the number of public complaints relating to Land Disturbance Permit projects.

Conclusion:
2016-2017
The program overall is functioning successfully.  Riverton staff focuses on education.  Most of the education is made through the SWPPP review process.  On average this year SWPPP reviews took 2-3 iterations before a LDP is issued, in past it took 4-5 iterations. This ensures the operator or at least the SWPPP preparer understands the SWPPP requirements.  Staff has found complete and coherent SWPPPs results in better compliance in addition to more meaningful documentation, however overall SWPPP implementation is still poor.  
Only 4 LDP holders stood out as making a genuine effort to maintain the SWPPP records, their sites were also well kept and City inspector oversight was minimal.  Three were small residential builders building a hand full of homes in developed subdivisions and one commercial builder.

However, most other residential home and commercial builders did not genuinely implement their SWPPPs and this was reflected by their site conditions and they received many warranted public complaints.  The City inspector reported non-compliance for more-less the same issues each month.  Many times the small residential and commercial builder Operator/SWPPP Manager was not on site and it appeared there was very little operator supervision of tradesmen and suppliers and the training records for tradesmen and suppliers were absent.  The big residential and commercial builders with full time inspectors were a step better, there was an increase in inspections and maintenance records which should be expected by companies with full time inspectors but far too often maintenance was inadequate and little effort if any was made to prevent the problems from reoccurring without City inspection and enforcement influence.  Even though an increase of issues and complaints is expected for large projects there were too many warranted public complaints and reoccurring non-compliance.  As with the small builder it appeared the tradesmen and suppliers of big builders were also not aware of the SWPPP requirements and training records were absent.




4.4 Right of Way Encroachment Permit
Year Executed: 2010
Reference Regulation:
4.2.4.3, 4.2.4.3.1, 4.2.4.4, 4.2.4.4.4, 4.2.4.5, 4.2.4.6, 4.2.6.4.5, 4.2.6.8
Target Pollutants:
Sediment, fugitive dust, cementitious material, trash, non-stormwater liquids, and nutrients.
Audiences:
Contractors, Utility Companies, City Staff
Description:
The Right of Way Encroachment Permit program involves a traditional permitting process using a permit application form as a vehicle for creating a contractual relationship and establishing terms and conditions that are supported by ordinance.  The Right-of-Way Encroachment Program has been practiced well before UPDES requirements to facilitate a safe project environment and infrastructure restoration satisfying Riverton Standards and other needs. The Right of Way Encroachment Program has been expanded to include requirements that will facilitate containment pollutants.  The program requires a pre-con where operational and structural BMPs relative to the unique construction project are determined and verbal instructions for BMP implementation are explained.  The program facilitates awareness and implementation of operational BMPs or installation of structural BMPs prior to disturbance of right of way for typical short term right of way encroachment projects.   The permitting process also facilitates obtaining a Land Disturbance Permit for longer term projects warranting Land Disturbance Permits.  The criteria for Land Disturbance permits are defined by the Right of Way Encroachment Permit SOP.
Measure of Success:
Success can be measured by comparing the number of clean vs unacceptable sites and the number of enforcement actions relative to the total number of permits issued.    
Record the number of permits issued for the report period.
Record the number of unacceptable site conditions for the report period.
Record the number of enforcement actions for the report period.
